Triglycerides
Synopsis
Triglycerides: A Nutrition and Natural-Health Reference
1. Definition and Basic Biology
Triglycerides consist of three fatty acids linked to glycerol. They are critical lipids, providing an energy source that is both compact and efficient; due to their hydrophobic nature, triglyceride molecules can pack together densely and so be stored in adipose tissue. Triglyceride molecules represent the major form of storage and transport of fatty acids within cells and in the plasma.
Fats, or triglycerides, within the body are ingested as food or synthesized by adipocytes or hepatocytes from carbohydrate precursors. When glucose levels are plentiful, the excess acetyl CoA generated by glycolysis can be converted into fatty acids, triglycerides, cholesterol, steroids, and bile salts. This process, called lipogenesis, creates lipids from the acetyl CoA and takes place in the cytoplasm of adipocytes and hepatocytes.
To be transported in the aqueous medium of plasma, triglycerides must be incorporated into lipoprotein particles along with other components such as cholesterol, phospholipid, and associated structural and regulatory apolipoproteins. Plasma triglyceride levels partially reflect the concentration of the triglyceride-carrying lipoproteins (TRL): very low-density lipoprotein (VLDL), chylomicrons, and their remnants.
2. Body Systems Involved
2.1 Liver
The liver is the central organ for fatty acid metabolism. Fatty acids accrue in the liver by hepatocellular uptake from the plasma. Under normal circumstances the liver stores only small amounts of fatty acids as triglycerides. In the setting of overnutrition and obesity, hepatic fatty acid metabolism is altered, commonly leading to the accumulation of triglycerides within hepatocytes, and to a clinical condition known as non-alcoholic fatty liver disease (NAFLD).
2.2 Adipose Tissue
Triglycerides serve as the primary storage form of energy in the body; they are stored in adipose tissue and can be mobilized when energy is required. This process is essential for maintaining energy homeostasis, particularly during periods of fasting or intense physical activity.
2.3 Intestinal Absorption
Lipid metabolism begins in the intestine, where ingested triglycerides are broken down into smaller chain fatty acids and subsequently into monoglyceride molecules by pancreatic lipases, enzymes that break down fats after they are emulsified by bile salts. When food reaches the small intestine in the form of chyme, a digestive hormone called cholecystokinin (CCK) is released by intestinal cells in the intestinal mucosa.
2.4 Cardiovascular System
Both moderate and severe hypertriglyceridemia are associated with a substantially increased long-term total mortality and cardiovascular risk. Furthermore, hypertriglyceridemia commonly leads to reduction in HDL and increase in atherogenic small dense LDL levels. Triglycerides themselves do not directly cause the fatty deposits that accumulate in atherosclerosis, but the cholesterol inside triglyceride-rich particles called very low-density lipoproteins (VLDLs) may add to the formation of plaques.
2.5 Pancreas
As well as affecting the heart and blood vessels, hypertriglyceridemia also increases the risk of pancreatitis or inflammation of the pancreas, the gland that produces insulin to control blood glucose level. Pancreatitis can cause problems with digestion, stomach pain, pancreatic damage, and eventually diabetes.
3. Reference Ranges and Classification
A triglyceride level is considered normal if it is below 150 mg/dL, while borderline ranges from 150 to 199 mg/dL, high from 200 to 499 mg/dL, and very high is 500 mg/dL or above. Some testing protocols require fasting, or not eating, for several hours before the blood is drawn. A lipoprotein profile, which includes a triglycerides test, should be done every five years for healthy adults.
Based on findings from the National Health and Nutrition Examination Survey (NHANES), serum triglycerides are usually higher in men than in women, especially until 70 years of age, and levels increase with age in both genders.
4. Hypertriglyceridemia: Etiology and Contributing Factors
4.1 Multifactorial Nature
Hypertriglyceridemia in many cases is multifactorial, resulting from the combination of genetic factors and other causes of increased production and/or impaired clearance of triglyceride-rich lipoproteins (TRLPs). Studies using stable isotope kinetic methods have shown that impaired lipid metabolism in obese subjects is caused by dual mechanisms: increased secretion of triglyceride-rich VLDL1 from the liver and delayed clearance of TRLs from the circulation. In contrast to the synthesis pathway, the clearance pathway explains 50% of the variation in total plasma triglycerides, making impaired catabolism of VLDL1-triglycerides the most important determinant of elevated plasma triglycerides.
4.2 Primary (Genetic) Causes
Hereditary lipid disorders can affect both triglycerides and cholesterol. These include familial combined hyperlipidemia, characterized by high triglycerides, high LDL cholesterol, and low HDL cholesterol; and familial hypertriglyceridemia (type IV familial dyslipidemia), characterized by high triglycerides alone.
4.3 Secondary Causes: Medical Conditions
Hypertriglyceridemia, defined as fasting serum triglyceride levels of 150 mg per dL or higher, is associated with increased risk of cardiovascular disease. Common risk factors include obesity, metabolic syndrome, and type 2 diabetes mellitus. Metabolic syndrome refers to a cluster of risk factors that includes high blood pressure, high triglycerides, high blood sugar, excess fat around the waist, and abnormal cholesterol levels.
4.4 Secondary Causes: Medications
Certain medications can cause elevated triglycerides, including second-generation antipsychotic drugs such as clozapine and olanzapine, antiretroviral protease inhibitors to treat HIV, non-selective beta-blockers, corticosteroids, cyclophosphamide, and oral estrogen.
4.5 Secondary Causes: Lifestyle
Less common risk factors include excessive alcohol use, physical inactivity, being overweight, and the use of certain medications. Hypertriglyceridemia has many causes including familial and genetic syndromes, metabolic disease, and drugs. Risks also appear to include diet, stress, physical inactivity, and smoking.
4.6 Cardiovascular Risk Debate
The main difficulty in isolating the effect of hypertriglyceridemia on cardiovascular risk is the fact that elevated triglyceride levels are commonly associated with concomitant changes in HDL, LDL, and other lipoproteins. As a result of this problem, its significance as a plausible therapeutic target was underestimated for many years. The totality of evidence suggests that elevated triglyceride levels likely contribute independently to increased risk of cardiovascular disease, although there is no consensus about appropriate target levels. Severely elevated triglyceride levels (500 mg per dL or higher) increase the risk of pancreatitis.
5. Dietary and Lifestyle Factors
5.1 Carbohydrates and Added Sugars
After people eat, the body turns any calories that have not been used up into triglycerides, which are stored in fat cells. If people regularly consume more calories than they need, they may develop high blood triglyceride levels. Increased added sugars are associated with important cardiovascular disease risk factors, including lower HDL-C levels, higher triglyceride levels, and higher ratios of triglycerides to HDL-C. It has been known for some time that carbohydrates can increase the risk of cardiovascular disease by altering lipid profiles.
The Framingham Heart Study found that frequent consumers of sugar-sweetened beverages had significantly increased liver fat and dysbiosis, including decreased HDL and increased triglyceride and cholesterol levels. When saturated fats are replaced with refined carbohydrates, and specifically with added sugars such as sucrose or high fructose corn syrup, the end result is not favorable for heart health. Such replacement leads to changes in LDL, HDL, and triglycerides that may increase the risk of coronary heart disease.
An umbrella review of sugar and health evidence published in The BMJ found that among meta-analyses of randomized controlled trials, evidence for postprandial triglycerides as an outcome was downgraded to "low" or "very low" quality owing to risk of bias, inconsistency, indirectness, or imprecision, indicating that the overall quality of the evidence base in this area is preliminary.
5.2 Fructose and High-Fructose Corn Syrup
In the National Health and Nutrition Examination Survey (NHANES, n=6,113), higher fructose consumers had more unfavorable lipid levels, including significantly lower HDL cholesterol, higher triglycerides, and a high ratio of triglycerides to HDL, whereas women also had higher LDL cholesterol levels. In the Framingham study, daily soft drink consumers had higher incidence of elevated triglycerides and low HDL cholesterol than non-consumers (relative risk: 1.22 for each).
5.3 Mediterranean Diet
The Mediterranean diet is characterized by high intake of olive oil and plant foods (fruits, vegetables, legumes, nuts, and non-refined cereals), low-to-moderate intake of dairy products, fish, and poultry, moderate intake of alcohol, and low intake of red meat and sweets. A 2018 systematic review and meta-analysis of RCTs found that compared to a control condition, there was strong evidence (p < 0.001) of a beneficial effect of promoting the Mediterranean diet and physical activity on triglycerides (β18.47 mg/dL, 95% CI β20.13, β16.80), as well as body weight, blood pressure, blood glucose, total cholesterol, and HDL-cholesterol.
A more recent systematic review of RCTs aimed to synthesize evidence on the combined effect of Mediterranean diet and physical activity on metabolic syndrome components in adults, including 22 RCTs published between 2018 and 2024, involving 11,478 participants. Improvements in HDL cholesterol, triglyceride levels, and insulin sensitivity were observed.
5.4 Physical Activity
Maintaining an active lifestyle decreases lipid disorders such as high plasma triglycerides and low HDL cholesterol. High levels of physical activity decrease type 2 diabetes mellitus, metabolic syndrome, and NAFLD. Research supports three to five sessions per week of moderate or vigorous physical activity, an equivalent of 150β200 min per week, for decreasing the development of NAFLD. The decrease in triglycerides associated with combined diet and exercise interventions may be mediated by enhanced fatty acid oxidation induced by exercise, along with lower availability of refined carbohydrates.
5.5 Alcohol
Excessive alcohol use β defined as more than two standard drinks daily in men and more than one standard drink daily in women β is considered a recognized risk factor for hypertriglyceridemia.
6. Nutrients, Herbs, and Natural Ingredients
The following sections strictly separate traditional use from scientific evidence. Evidence strength (e.g., in-vitro only, animal study, small RCT, large meta-analysis, GRADE rating) is stated explicitly for each ingredient.
6.1 Omega-3 Fatty Acids (EPA and DHA)
Traditional Use
Coastal and Arctic populations, including Inuit and Scandinavian communities, have consumed fatty fish as a dietary staple for centuries. Fish oil was historically pressed and used as a nutritional and topical remedy in Northern European folk medicine, though historical records did not frame its use in terms of blood lipids.
Scientific Evidence
Omega-3 fatty acids, specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), may reduce the risk of atherosclerotic cardiovascular disease events through various mechanisms, including triglyceride lowering, membrane stabilization, and antithrombotic, anti-inflammatory, or antiarrhythmic properties.
A systematic review of RCTs covering 1994β2003 found that ten studies reported long-chain omega-3 fatty acids to be effective in the treatment of hypertriglyceridemia, with an average decrease in triglycerides of 29%, total cholesterol 11.6%, and VLDL 30.2%. Eligible studies evaluated effects of long-chain omega-3 fatty acids (EPA or DHA) at doses of 3 g per day or more, for people with total triglyceride levels over 150 mg/dL or total cholesterol over 200 mg/dL.
A 2025 systematic review and dose-response meta-analysis of 23 RCTs encompassing 2,061 patients with coronary heart disease found that omega-3 fatty acid supplementation significantly reduced circulating levels of triglycerides (standardized mean difference [SMD] = β0.25, 95% confidence interval [CI] = β0.38 to β0.11) and total cholesterol (SMD = β0.12, 95% CI = β0.23 to β0.02), with no significant impact on HDL-C, LDL-C, or arterial plaque volume. The GRADE assessment indicated that the quality of evidence for improvements in triglycerides and total cholesterol was moderate, supporting the use of omega-3 fatty acids as adjunctive therapy for lipid management in patients with coronary heart disease.
Evidence from large cardiovascular outcome trials is mixed. Two recent negative trials of EPA + DHA β STRENGTH and OMEMI β have put under discussion the utility of omega-3 fatty acids in preventing atherosclerotic cardiovascular events. The triglyceride-lowering effect is considered among the most robust findings; however, whether this translates uniformly to reduced cardiovascular events remains contested.
6.2 Niacin (Vitamin B3)
Traditional Use
Niacin deficiency (pellagra) was recognized and treated with dietary sources such as brewer's yeast and liver in early 20th-century nutritional medicine. Its use specifically for lipid management is a pharmacological development of the mid-20th century, not rooted in pre-modern herbal traditions.
Scientific Evidence
Niacin is indicated to reduce elevated total cholesterol, LDL cholesterol, apolipoprotein B, and triglycerides, and to increase HDL cholesterol in patients with primary and mixed dyslipidemia. When used as an adjunct to diet, niacin reduces elevated total cholesterol. Studies indicate that niacin inhibits the production of very-low-density lipoprotein (VLDL) in the liver. VLDL transports both triglycerides and cholesterol, and once in circulation, VLDL is broken down in capillary beds, releasing triglycerides for energy utilization or storage in adipose tissue.
Despite well-documented biochemical activity, clinical utility is limited in practice. People who take niacin in addition to common cholesterol medicines see very little additional benefit, and niacin can cause uncomfortable and sometimes dangerous side effects. Many clinicians use nicotinic acid (niacin or vitamin B3) in patients who are statin-intolerant in the management of hypertriglyceridemia, despite it no longer being recommended for LDL-C reduction. Evidence strength for triglyceride lowering is established but clinical benefit as an add-on is currently considered weak to moderate based on large outcome trials.
6.3 Berberine
Traditional Use
Berberine (BBR) is a protoberberine isoquinoline alkaloid isolated from many species of plants such as Berberis aquifolium or Coptis chinensis, which has been extensively used in traditional medicine. In Traditional Chinese Medicine (TCM), berberine-containing plants such as Coptis chinensis (Huanglian) have been used for thousands of years for conditions including diarrhea, infections, and metabolic complaints. Its use specifically for blood lipids is a modern pharmacological framing.
Scientific Evidence
Several recent meta-analyses of randomized clinical trials have provided compelling evidence for the lipid and lipoprotein-modulating effects of berberine alone and combined with statins. Compared with statins alone, berberine plus statins was more effective in lowering triglyceride and total cholesterol.
A systematic review and meta-analysis of placebo-controlled trials found that berberine significantly reduced triglycerides, with an average decrease of approximately 0.37 mmol/L (roughly 33 mg/dL). Study doses ranged from 300 to 1,500 mg per day, typically split into two or three doses, over periods of 84 to 140 days. Proposed mechanisms include activating the AMPK pathway, improving insulin sensitivity and glucose metabolism, regulating mitochondrial function, reducing inflammation and oxidative stress, and regulating the intestinal microenvironment.
A meta-analysis of animal studies on NAFLD found that 31 studies involving 566 animals were included, and results showed that total cholesterol, triglycerides, ALT, AST, HDL-C, LDL-C, fasting blood glucose, fasting insulin, and free fatty acids in the berberine-treated group were significantly restored compared to the model group. This preclinical evidence is strong but cannot be directly extrapolated to humans; human RCT data are promising yet most clinical treatment strategies and meta-analyses for metabolic disorders have studied berberine in combined-medicine protocols, and evidence to disclose the therapeutic effect of berberine treatment alone is limited. Overall, evidence strength in humans is moderate, limited by trial quality and size.
6.4 Turmeric and Curcumin (Curcuma longa)
Traditional Use
Turmeric (Curcuma longa) has been used for approximately 4,000 years in Ayurvedic and traditional South Asian medicine, primarily for its anti-inflammatory properties. It has been used topically for wound healing and internally for digestive complaints, liver support, and metabolic conditions. Traditional Ayurvedic formulations typically involved dried rhizome powder in food or milk preparations. Its use for blood lipids is not explicitly documented in classical Ayurvedic texts but falls within the broader category of its recognized effects on kapha-related imbalances.
Scientific Evidence
A 2023 systematic review and dose-response meta-analysis including 64 RCTs found that turmeric/curcumin supplementation exerts statistically significant improvements on blood levels of total cholesterol (WMD = β3.99 mg/dL), triglycerides (WMD = β6.69 mg/dL; 95% CI = β7.93, β5.45), LDL-C (WMD = β4.89 mg/dL), and HDL-C (WMD = +1.80 mg/dL). Between-study heterogeneity was significant, which tempers these conclusions.
An earlier meta-analysis of RCTs in patients with cardiovascular risk factors found that turmeric and curcumin significantly reduced serum LDL-C and TG levels compared to control groups. Turmeric and curcumin appeared safe, with no serious adverse events reported in the included studies. They may protect patients at risk of CVD through improving serum lipid levels, and curcumin may be used as a well-tolerated dietary adjunct to conventional drugs.
Evidence is complicated by significant heterogeneity across formulations. RCTs investigating turmeric, curcumin, and curcuminβpiperine combinations have produced inconsistent findings. Some studies report clinically meaningful reductions in LDL-C (>20 mg/dL) and triglycerides, while others show neutral or modest results. Variability in study populations, intervention duration, formulations, and methodological quality contribute to these discrepancies. Overall, evidence is preliminary to moderate, particularly hampered by bioavailability challenges with standard curcumin formulations.
6.5 Garlic (Allium sativum)
Traditional Use
Garlic has been used medicinally for over 5,000 years across ancient Egyptian, Greek, Roman, Chinese, and Indian traditions. In Ayurveda and TCM it has been used for cardiovascular complaints, infections, and digestive issues. In European folk herbalism, garlic preparations β including raw cloves, macerated oil, and vinegar extracts β were employed for what would today be described as circulatory conditions. The active constituent allicin was not identified until the 20th century.
Scientific Evidence
A 2024 meta-analysis of 21 RCTs in patients with dyslipidemia found that garlic consumption significantly reduced total cholesterol (WMD = β0.64 mmol/L), triglycerides (WMD = β0.17 mmol/L, 95% CI = β0.26 to β0.09, P < 0.001), and LDL-C, while slightly increasing HDL-C. The GRADE approach was used to evaluate the overall certainty of the evidence.
The triglyceride-lowering effect of garlic is statistically significant across multiple meta-analyses but the absolute magnitude is modest. Evidence quality is rated as moderate by recent GRADE assessments. Heterogeneity across garlic preparations (raw, aged, powder, oil, allicin-standardized extracts) contributes to variability across trials.
6.6 Soluble Dietary Fiber (Psyllium, Beta-Glucan, Pectin)
Traditional Use
Psyllium (Plantago ovata) husk has been used in Ayurvedic and Unani medicine as a bulk laxative and for general digestive health. Oats and barley have been dietary staples in Northern and Central Europe for millennia. Traditional use did not frame these foods in terms of lipid modulation; their use as specific cholesterol or triglyceride remedies is a 20th-century development.
Scientific Evidence
A 2023 systematic review and dose-response meta-analysis of RCTs found that soluble fiber supplementation resulted in significant reductions of total cholesterol and LDL cholesterol, without a significant reduction in triglyceride levels in one pooled analysis. However, more specific data on psyllium show a different picture: in a clinical comparison at six months, only the psyllium group (not the guar gum group) exhibited a significant improvement in plasma triglyceride concentration (β13.3%), as well as systolic and diastolic blood pressure. A meta-analysis of 8 RCTs on the effect of psyllium consumption in people with type 2 diabetes reported significant reductions in triglycerides and LDL cholesterol.
The U.S. Food and Drug Administration, in 2006, authorized a health claim that psyllium husk, beta-glucan in oats, and beta-glucan in barley can reduce the risk of heart disease. This claim specifically pertains to LDL cholesterol rather than triglycerides. The evidence for triglyceride reduction with soluble fiber is mixed and weaker than that for LDL cholesterol. Overall evidence strength for triglyceride lowering specifically is preliminary to moderate, being more consistent in populations with concomitant metabolic disorders such as type 2 diabetes.
6.7 Fenugreek (Trigonella foenum-graecum)
Traditional Use
Fenugreek seeds have a long history of use in Ayurvedic medicine for digestive ailments, blood sugar regulation, and postpartum recovery. In the traditional medicine of South Asia, North Africa, and the Middle East, fenugreek seeds were consumed directly, ground into pastes, or decocted in water. Their lipid-modulating potential was not a primary traditional indication, though their use for metabolic and digestive function overlaps conceptually.
Scientific Evidence
In animal studies, diabetic rats given a fiber-rich fraction of fenugreek showed condensed triglycerides, total cholesterol, and LDL. In clinical trials, however, the picture is less consistent. A systematic review and meta-analysis of clinical trials in patients with type 2 diabetes revealed that fenugreek supplementation did not significantly affect triglycerides. Significant effects were found for fasting plasma glucose, HbA1c, HOMA-IR, total cholesterol, LDL-C, HDL-C, and BMI; however, the effect on fasting insulin, triglycerides, and weight was not statistically significant.
Most fenugreek trials have been of low methodological quality, and the evidence base for triglyceride lowering specifically is currently weak. Its more robustly supported effects in humans relate to glycemic control.
7. Associated Metabolic and Health Conditions
The complexities of triglyceride metabolism extend beyond energy production, influencing various aspects of health including obesity, diabetes, cardiovascular diseases, and fatty liver disease.
- Non-Alcoholic Fatty Liver Disease (NAFLD): In the setting of overnutrition and obesity, hepatic fatty acid metabolism is altered, commonly leading to the accumulation of triglycerides within hepatocytes, and to a clinical condition known as NAFLD.
- Metabolic Syndrome: Metabolic syndrome refers to a cluster of risk factors that includes high blood pressure, high triglycerides, high blood sugar, excess fat around the waist, and abnormal cholesterol levels.
- Type 2 Diabetes: Part of the difficulty in providing specific clinical recommendations for hypertriglyceridemia has been the frequent coexistence of elevated triglycerides with other conditions that affect cardiovascular disease risk, such as depressed HDL-cholesterol, obesity, metabolic syndrome, proinflammatory and prothrombotic biomarkers, and type 2 diabetes.
- Pancreatitis: Severe hypertriglyceridemia is associated with an increased risk of acute pancreatitis.
8. Summary of Evidence Strength by Intervention
- Omega-3 fatty acids (EPA/DHA): Strong to moderate evidence for triglyceride lowering from multiple meta-analyses of RCTs; GRADE-assessed as moderate for adjunctive use. Cardiovascular outcome evidence is mixed across large trials.
- Niacin (vitamin B3): Established biochemical and pharmacological evidence for triglyceride and VLDL reduction; clinical utility as an add-on to statins has been questioned by large outcome trials. Side-effect profile limits use.
- Berberine: Moderate human evidence from meta-analyses of RCTs; preclinical (animal) evidence is strong. Human trial quality and sample sizes remain limiting factors.
- Turmeric/Curcumin: Preliminary to moderate evidence from large numbers of RCTs; significant heterogeneity and bioavailability concerns. Effect sizes on triglycerides are modest.
- Garlic: Moderate evidence from multiple RCT meta-analyses; absolute triglyceride reduction is modest. Variation across preparations limits direct comparisons.
- Soluble fiber (psyllium, beta-glucan): Mixed to moderate for triglycerides specifically; strongest effect is on LDL cholesterol. Most consistent triglyceride benefit seen in populations with type 2 diabetes.
- Fenugreek: Weak evidence for triglyceride lowering in humans from RCTs; animal data are more supportive. Evidence is stronger for glycemic outcomes.
- Mediterranean diet + physical activity: Strong evidence from multiple systematic reviews of RCTs, with pooled reductions in triglycerides reaching β18.47 mg/dL in meta-analysis.

Natural Remedies
Ingredients
- acaciaScientific
Multiple clinical trials demonstrate that acacia gum significantly reduces serum triglycerides. A case-control trial in hyperlipidemia patients found 30 g/day for 4 weeks reduced triglycerides by 38.2%. A trial in type 2 diabetic patients found a 10.95% reduction in triglycerides with 30 g/day over 3 months. A trial in sickle cell anemia patients also confirmed triglyceride reductions.
- adzuki beanScientific
Adzuki bean extract significantly reduced triglycerides in spontaneously hypertensive rats in a dose-dependent manner. A human RCT showed a non-significant trend toward triglyceride reduction. GABA-enriched adzuki bean diets inhibit triglyceride synthesis via AMPK/SREBP1c downregulation in animal models.
- agrimonyScientific
In the only published human RCT on agrimony (Cho et al., J Med Food 2018), agrimony aqueous extract produced a statistically significant reduction in serum triglycerides (P=0.020) versus placebo at 8 weeks in subjects with elevated liver enzymes. This is the primary human-level evidence for agrimony's triglyceride-lowering effect.
- ajwainScientific
Animal studies in rabbits and rats have documented significant reductions in serum triglycerides with ajwain seed powder supplementation, with one study reporting a 53% reduction at 2 g/kg. This lipid-lowering property is consistently cited in peer-reviewed pharmacological reviews. Human clinical data are absent.
- akkermansia muciniphilaScientific
Human observational data show A. muciniphila abundance inversely correlates with plasma triglycerides. In the Depommier et al. 2019 RCT, triglycerides trended lower in treated groups versus placebo, though this did not reach statistical significance in the small pilot. Animal studies robustly show A. muciniphila reduces hepatic triglyceride synthesis and serum triglycerides. A. muciniphila metabolites inhibit lipogenic gene expression and enhance fatty acid oxidation.
- ALA (alpha-linolenic acid)Scientific
Alpha-linolenic acid (ALA) is an essential plant-derived omega-3 fatty acid found in flaxseed, walnuts, and chia seeds. Whole flaxseed supplementation (the primary dietary source) has been shown in multiple RCTs and meta-analyses to significantly reduce triglycerides. ALA's conversion to EPA and DHA in the body is limited but contributes to the lipid-lowering effect.
- ALA (alpha-lipoic acid)Scientific
A systematic review and meta-analysis of 10 RCTs (2019) found ALA supplementation significantly reduced serum triglycerides by a weighted mean difference of β29.2 mg/dL versus placebo. An RCT in metabolic syndrome patients (600 mg/day, 12 weeks) found significant TG reductions of β36.8 mg/dL in the ALA group versus +6.2 mg/dL in placebo.
- alfalfaScientific
Multiple animal studies and at least one human trial show alfalfa extracts lower serum triglycerides alongside total cholesterol and LDL. Saponins and flavonoids appear to mediate lipid-lowering effects through hepatic gene regulation. Human clinical data are limited but directionally consistent.
- algal oilScientific
Algal oil is a vegetarian/vegan source of DHA (and sometimes EPA) derived from marine microalgae. It provides the same long-chain omega-3s as fish oil at equivalent doses and has comparable triglyceride-lowering bioavailability, making it an evidence-based alternative for individuals who avoid fish products.
- almondScientific
Evidence for almond-specific triglyceride reduction is inconsistent. Some earlier studies and traditional use attributed triglyceride-lowering effects to almonds, but a 2025 RCT specifically in adults with metabolic syndrome found almond consumption did not significantly alter triglyceride concentrations. Meta-analyses show variable and population-dependent effects.
- aloe veraScientific
Multiple RCTs and a systematic meta-analysis of five RCTs (415 participants) demonstrate that aloe vera supplementation significantly reduces serum triglycerides in pre-diabetic and early diabetic patients. A double-blind RCT in 72 pre-diabetic subjects found triglyceride levels significantly decreased after four weeks with 500 mg aloe vera extract.
- amaranthScientific
Several clinical and preclinical studies report that amaranth consumption reduces serum triglyceride levels. A randomized trial of amaranth seed oil in obese patients showed significant triglyceride reduction. An A. caudatus extract study also found triglyceride reductions alongside blood glucose improvements. Animal data and in vitro studies support a hypolipidemic effect on triglycerides.
- anchoviesScientific
EPA and DHA from anchovies are among the most robustly evidence-supported nutrients for lowering elevated triglycerides. A dose-response meta-analysis in JAHA found a mean TG reduction of ~43 mg/dL at 2 g/day and ~69 mg/dL at 3 g/day EPA+DHA. A separate meta-analysis specifically in metabolic syndrome patients confirmed significant TG reduction (SMD=β0.39) with n-3 PUFA supplementation.
- andrographisScientific
A clinical study in 60 patients with modest hypertriglyceridemia found that andrographolide extract at 120 mg/day improved serum triglyceride levels. Animal studies further corroborate hypolipidemic effects on triglycerides, and clinical trial data in T2DM patients has also assessed triglyceride outcomes.
- annattoScientific
Clinical trials consistently show annatto delta-tocotrienol reduces serum triglycerides. In hypercholesterolemic patients, 250 mg/day lowered triglycerides by 14% within 4 weeks. In a 24-week T2DM RCT (n=110), triglycerides fell 10.3%. An RCT in metabolic syndrome (n=82) combining tocotrienol with resveratrol reduced triglycerides by 16%.
- appleScientific
Apple polyphenols and pectin have shown triglyceride-lowering effects in preclinical models and some human RCTs, attributed to modulation of hepatic lipid metabolism and gut microbiota-mediated SCFA production. The RCT meta-analysis data on triglycerides are inconclusive overall but favorable trends are observed in metabolic subgroups.
- apple cider vinegarScientific
Meta-analyses of RCTs show ACV consumption is associated with modest but statistically significant reductions in serum triglycerides. An 18-week RCT in obese subjects found reductions in triglycerides alongside modest weight loss. Mechanisms are attributed to acetic acid's effects on lipid metabolism and hepatic fatty acid oxidation.
- apricotScientific
Human clinical data on apricot seeds and triglycerides are mixed: a 12-week study found a significant increase in triglycerides, while a 42-day study found no significant change. Animal studies with apricot kernels show reductions in triglycerides in diabetic models.

- hesperidinScientific
Clinical RCTs and meta-analyses demonstrate that hesperidin significantly reduces serum triglyceride (TG) levels. A 2024 meta-analysis of nine RCTs found significant TG reduction (p=0.03). A randomized double-blind trial in 80 post-coronary artery bypass graft (CABG) patients showed 200 mg/day hesperidin for 12 weeks significantly reduced TG vs. placebo. Mechanistically, hesperidin activates LPL and reduces hepatic TG synthesis.
- hibiscusScientific
Several RCTs and a 2022 meta-analysis found that Hibiscus sabdariffa at doses of 500β1000 mg/day produced improvements in lipid profiles including triglycerides in adults. An 8-week RCT of a hibiscus-inulin formulation significantly reduced the triglyceride-glucose (TyG) index versus placebo. Results across RCTs are mixed for isolated triglyceride lowering.
- HMR lignanScientific
In a high-fat diet mouse model, HMRlignan (TEP form) reduced serum triglycerides by approximately 15%. The metabolites enterolactone and enterodiol also reduced TAG uptake in hepatoma cells in vitro by ~10%. These findings are preclinical only, with no human RCT data on triglyceride endpoints.
- honeyScientific
Clinical trials show that honey consumption reduces serum triglycerides, particularly in individuals with elevated baseline values. The Al-Waili RCT (n=55) found 70 g/day honey for 30 days reduced triglycerides by 11% in normal individuals and 19% in those with elevated levels versus sucrose. GRADE-assessed meta-analyses confirm honey's modest triglyceride-lowering effect.
- huckleberryScientific
RCT meta-analyses confirm that Vaccinium anthocyanin supplementation produces modest but statistically significant reductions in serum triglycerides. Huckleberry's anthocyanin composition is consistent with the Vaccinium genus compounds responsible for these effects. A dedicated Vaccinium RCT confirmed triglyceride-lowering in hyperlipidemic patients.
- hydroxycitric acidScientific
Because HCA inhibits ATP-citrate lyase, it directly curtails the acetyl-CoA supply for hepatic triglyceride synthesis. Human clinical trials and a 2024 meta-analysis of RCTs have reported modest but statistically significant reductions in serum triglycerides with HCA supplementation.
- indian baelScientific

- isomalto-oligosaccharideScientific
IMO supplementation has been shown to reduce fasting triglyceride levels in hemodialysis patients and in hyperlipidemic subjects consuming IMO-fortified foods. Animal studies corroborate reduced hepatic lipid accumulation. SCFA production from IMO fermentation may inhibit hepatic triglyceride synthesis.
- jiaogulanScientific
Jiaogulan has been shown to lower serum triglycerides in multiple studies, achieving this by improving hepatic fat metabolism and redirecting carbohydrates toward muscle energy rather than triglyceride synthesis. A 2022 systematic review of 22 RCTs in 2,407 dyslipidemia patients supports its lipid-lowering efficacy.
- jujubeScientific
An RCT in T2D patients (n=48, 12 weeks, 30 g/day dried jujube) reported a significant ~14% reduction in serum triglycerides versus baseline and versus control. Animal studies show consistent lipid-lowering effects. A meta-analysis of RCTs found generally favorable TG trends but noted the limited number of qualifying trials.
- kaleScientific
Animal studies consistently show kale supplementation reduces plasma triglycerides, and the Kyushu University kale powder trial found improved overall lipid metabolism including triglycerides in metabolic syndrome subjects. Sulforaphane analogue research implicates the Nrf2/PPARΞ± axis in triglyceride reduction. Clinical evidence is preliminary but mechanistically grounded.
- kelpScientific
Kelp-derived fucoidan and alginate have shown triglyceride-lowering effects in animal and some clinical studies. PMC data confirm fucoidan from Laminaria japonica reduced total cholesterol and triglycerides in high-fat-fed mice. Preclinical and limited clinical trial data support this effect, though large human RCTs are lacking.
- kidney beansScientific

- knotweedScientific
A 2025 meta-analysis of 7 RCTs (n=337) published in Clinical and Experimental Medicine found resveratrol significantly reduced triglycerides, though it showed no significant effects on total cholesterol, LDL, or HDL. Emodin from knotweed promotes lipid metabolism via AMPK and PPAR pathways. Polydatin from PC demonstrated hypolipidemic activity in clinical trials.
- krill oilScientific
Krill oil delivers EPA and DHA in phospholipid form, which may offer enhanced bioavailability compared to standard fish oil. Clinical studies and a systematic review/meta-analysis support its ability to reduce plasma triglycerides in humans, consistent with the known omega-3 triglyceride-lowering mechanism.
- kudzuScientific
Puerarin has been shown in animal models to reduce hepatic and serum triglyceride levels, and a 2026 preclinical systematic review confirmed significant triglyceride-lowering effects across multiple NAFLD animal studies. Clinical data in humans show puerarin as part of diabetes management reduces lipid parameters. Traditional use does not specifically address triglycerides.
- L-arginineScientific
A 2019 meta-analysis of 12 RCTs demonstrated that L-arginine supplementation leads to a significant reduction in serum triglyceride (TAG) levels, while not significantly affecting total cholesterol, LDL, or HDL. A separate meta-analysis of 13 trials confirmed a borderline significant triglyceride-lowering effect (WMD: β6.03 mg/dL; P=0.04). Higher doses (β₯8 g/day) appear most effective.
- l-carnitineScientific
L-carnitine supplementation has been shown to modestly reduce triglyceride levels in dyslipidemic and diabetic populations, though some meta-analyses show inconsistent results. A WebMD clinical review states oral or IV L-carnitine improves cholesterol and triglyceride levels by a small amount. A NIH ODS review found mixed triglyceride effects.
- L-carnosineScientific
An RCT in T2D patients found that 1 g/day L-carnosine for 12 weeks significantly attenuated serum triglycerides alongside fasting glucose and AGEs. A meta-analysis of carnosine RCTs included triglycerides as an endpoint. Human evidence is limited to a small number of trials in metabolic disease populations.
- L-glycineScientific
A PubMed review of glycine's effects on metabolic syndrome components concludes that glycine supplementation improves hyperlipidemia, including elevated triglycerides, alongside other components of metabolic syndrome. Lower plasma glycine is consistently found in metabolic syndrome patients, and supplementation partially reverses this defect.
- lactobacillus bulgaricusScientific
A randomized pilot trial (n=36 overweight adults, 12 weeks) found that L. bulgaricus supplementation at 10^8 CFU/day produced a notable decrease in blood triglyceride (TG) levels and reduced TG proportions in large VLDL and HDL fractions, despite no significant effect on body weight or BMI.
- lactobacillus gasseriScientific
Animal model studies show multiple L. gasseri strains reduce triglyceride levels in high-fat diet contexts, and a human study using L. gasseri CHO-220 combined with inulin reported reductions in total cholesterol and LDL in hypercholesterolemic subjects. Direct evidence for triglyceride lowering by L. gasseri monotherapy in large human RCTs is still limited.
- lactobacillus plantarumScientific

- lactobacillus salivariusScientific
The same RCT demonstrating cholesterol-lowering effects of L. salivarius UBL S22 also found significant triglyceride reductions after 6 weeks versus placebo in 45 healthy volunteers. Both the probiotic-alone and synbiotic groups showed significant (P < .05) triglyceride decreases.
- lecithinScientific
Soy lecithin (phosphatidylcholine) has been used as a lipid-lowering supplement with evidence from clinical studies for modest triglyceride reduction via enhanced VLDL-TG processing and transport. It is listed among natural treatments for high cholesterol by evidence-based complementary medicine databases.
- lemonScientific
Citrus extracts, including lemon-derived flavonoids, have clinically demonstrated triglyceride-lowering effects. A double-blind RCT in hypercholesterolemic subjects found citrus extract plus vitamin C significantly lowered triglycerides versus placebo. A citrus flavonoid RCT showed 24β34% reductions in triglycerides over 12 weeks.
- lemon balmScientific
A 2024 meta-analysis of 5 RCTs (n=302) found that lemon balm supplementation significantly lowers triglycerides. Earlier clinical trials and a 2020 meta-analysis showed mixed results for triglycerides alone, but the more recent and larger synthesis supports a significant effect. Mechanistic data from animal studies suggest inhibition of SREBP-1c-dependent fatty acid synthesis.
- lemongrassScientific
Lemongrass extract and essential oil have repeatedly been shown to reduce triglycerides in animal diabetes and metabolic models. Studies showed significant decreases in triglyceride levels at dosages of 400β800 mg alongside reductions in glucose and insulin. The effect is corroborated across multiple independent animal studies, though human RCTs are absent.
- lentinula edodes myceliaScientific
Multiple preclinical studies show LEM and L. edodes mycelial preparations significantly reduce serum triglycerides, with reductions up to 44.5% in diabetic rat models. The active compound eritadenine appears to suppress lipid synthesis and alter hepatic fatty acid metabolism. Human clinical evidence is currently lacking.
- lignansScientific
Studies of flax lignan supplementation during exercise training in individuals aged 50+ showed reductions in triacylglycerols as part of metabolic syndrome risk factor improvements. Sesamin supplement trials also indicated possible lipid-lowering associations including triglycerides. Evidence comes primarily from flaxseed-based trials where lignans are one of multiple active components.
- limeScientific
Clinical evidence from citrus trials, including one RCT using lime and cumin capsules, shows significant triglyceride reductions. A meta-analysis of citrus RCTs found an average triglyceride reduction of ~62 mg/dL. Lime's flavonoids and limonoids are the proposed active components.
- limoneneScientific
Animal studies consistently demonstrate D-limonene lowers serum triglycerides in high-fat diet and obese rodent models, alongside reductions in LDL cholesterol and improvements in HDL. A 2025 PMC review confirmed that D-limonene consistently improves lipid profiles by decreasing LDL and triglycerides while raising HDL across multiple diabetic animal models. No human clinical trials have specifically examined triglyceride-lowering effects.
- lion's maneScientific
Animal studies consistently show Lion's Mane extracts lower serum triglycerides. A polysaccharide fraction reduced triglycerides by 34.3% in a hyperlipidemic animal model. A diabetic rat model also showed improved triglyceride levels with 28-day aqueous extract treatment. Human-specific triglyceride data remain absent.
- lotus seedScientific
Lotus plant extracts including lotus seed-related preparations consistently reduce serum triglycerides in animal models of obesity and dyslipidemia. A clinical reference reports triglyceride reductions with lotus leaf water extract in hyperlipidemia patients. Lotus seed-specific human trials are absent.
- luteolinScientific
Luteolin-containing nutraceuticals reduced triglycerides in human RCT subjects, and preclinical data show luteolin modulates hepatic triglyceride synthesis via PPAR and SREBP pathways. Animal evidence shows mixed triglyceride effects depending on dose and model.
- lycheeScientific
A 12-week RCT in overweight/obese women found that oligonol (lychee-derived polyphenol) supplementation produced lower triglyceride levels compared to placebo. Multiple in vitro and animal studies further support lychee extracts' hypolipidemic properties, including regulation of fat metabolism. This makes triglyceride reduction one of the better-evidenced clinical endpoints for lychee-derived supplements.
- macadamiaScientific
Meta-analyses of tree nut RCTs including macadamia nuts show reductions in fasting triglycerides, particularly in individuals with hypertriglyceridemia. A meta-analysis of 47 RCTs found ~2 oz/day of tree nuts decreased triglycerides by 0.06 mmol/L over ~8 weeks in metabolic syndrome subjects. However, controlled feeding trials specific to macadamia nuts did not consistently show triglyceride-lowering effects.
- magnesiumScientific
The relationship between magnesium supplementation and triglycerides is clinically studied but results are mixed. Some systematic reviews report a trend toward triglyceride reduction with magnesium, particularly in diabetic or hypomagnesemic populations, while a 2017 meta-analysis of RCTs found no statistically significant effect on triglyceride concentrations. Mechanistically, magnesium influences lipid-metabolizing enzymes including lipoprotein lipase and HMG-CoA reductase.
- maitake mushroomScientific
Multiple preclinical studies in hyperlipidemic and diabetic animal models demonstrate maitake supplementation significantly reduces serum triglycerides. A PMC systematic review on mushroom consumption found limited experimental evidence supporting triglyceride reduction. Human-specific RCT data for maitake and triglycerides are sparse.
- mangoScientific
Human trial evidence for mango's effect on triglycerides is mixed. A 12-week study in overweight/obese adults found that mango consumption prevented the significant triglyceride rise seen in the low-fat cookie control group. However, several other RCTs found no significant change in triglycerides with mango intake.
- mangosteenScientific
Clinical RCTs using a mangosteen/Sphaeranthus indicus combination in obese subjects found significant reductions in serum triglycerides. Animal studies consistently show mangosteen extract lowers triglycerides via AMPK activation and pancreatic lipase inhibition. A human prospective study in cardiovascular-risk patients provided supporting biomarker evidence.
- marjoramScientific
In a high-fat diet hepatosteatosis rat model, both doses of hydroalcoholic marjoram extract (150 and 450 mg/kg/day) produced statistically significant reductions in serum triglycerides compared to untreated high-fat diet controls (P<0.001).
- MCT (medium chain triglycerides)Scientific
A systematic review and meta-analysis of randomized trials (Journal of Nutrition, 2021) found that MCT oil (C6βC10) does not significantly affect total cholesterol or LDL but causes a small increase in serum triglyceride concentration compared to unsaturated fat controls. The effect on triglycerides is context-dependent: excess MCT consumed beyond caloric needs can increase de novo hepatic lipogenesis and raise fasting plasma triglycerides.
- milk thistleScientific
Milk thistle (Silybum marianum) and its active complex silymarin have been studied in RCTs and meta-analyses for lipid effects including triglyceride reduction, particularly in patients with fatty liver disease (NAFLD/NASH) and T2D. The combination of berberine with silymarin shows significant TG reduction in multiple RCTs.
- millet seedScientific
A meta-analysis of 19 studies demonstrated a 9.5% reduction in triacylglycerol levels with millet consumption over as little as 21 days to 4 months. Four studies showed triglyceride levels normalizing to below 150 mg/dL. These effects are attributed to dietary fiber, PUFAs, and phytosterol content of millet seeds.
- momordicaScientific
Momordica charantia has been evaluated for triglyceride-lowering effects in both animal models and human RCTs. Preclinical studies consistently show TG reduction; RCT data in humans are inconsistent and the Frontiers in Nutrition meta-analysis did not find a statistically significant effect. Animal and in vitro evidence is robust.
- morindaScientific
The same randomised double-blind placebo-controlled clinical trial (n=132 heavy smokers) that documented cholesterol-lowering effects of M. citrifolia noni juice also found significant triglyceride reductions. Animal models consistently confirm triglyceride-lowering activity across fruit, leaf, and root extracts.
- morusScientific
Human RCTs demonstrate that Morus preparations significantly reduce serum triglycerides. A 2024 randomised crossover clinical trial in obese individuals found concentrated mulberry drink significantly lowered triglycerides versus placebo. Meta-analysis data corroborate this benefit.
- mulberryScientific
Human RCT evidence and a pooled meta-analysis show mulberry supplementation significantly reduces serum triglycerides. A crossover trial in obese adults found significant triglyceride reduction vs. placebo. The 2025 meta-analysis (15 RCTs) reported a significant pooled TG-lowering effect.
- mustardScientific
Animal studies with mustard seed phytosterol extracts demonstrate significant reductions in serum triglycerides. The omega-3 fatty acids and plant sterols in mustard seeds mechanistically support triglyceride lowering. The Cardiff pre-diabetic human pilot and animal pharmacology suggest clinical relevance, though dedicated human RCTs for triglycerides specifically are lacking.
- myrobalanScientific
TC aqueous extract significantly reduced serum triglyceride levels in diabetic animal models. Preclinical data show dose-dependent reduction at 1,000 mg/kg body weight, with TG levels falling from 216 to 135 mg/dL in diabetic rats.
- naringinScientific
Naringin and naringin-containing bergamot extracts reduce triglycerides in human clinical studies. A 6-month open-label trial with 80 hypercholesterolemic subjects found bergamot flavonoids (containing 37% naringin) reduced triglycerides from 159 to 133 mg/dL. A 237-subject 30-day study with naringin-containing bergamot extract also significantly decreased triglycerides.
- nattokinaseScientific
Human RCT data on nattokinase and triglycerides are mixed and dose-dependent. A 2023 meta-analysis of six RCTs (n=546) found no statistically significant effect of nattokinase on triglyceride levels at low-to-moderate doses. However, a large clinical study (n=1,062) at 10,800 FU/day found a 15.3% reduction in triglycerides over 12 months, and a 90-day RCT in CAD patients found NK combined with red yeast rice reduced triglycerides by 0.39 mmol/L. NK is proposed to activate lipoprotein lipase, enhancing triglyceride catabolism.
- neem treeScientific
Both RCTs measuring lipid profiles in T2DM and metabolic syndrome patients included triglyceride (TG) assessment; neem supplementation produced measurable reductions. Animal studies report up to 32% reduction in triglycerides with single-dose neem extract administration. Hypolipidaemic mechanisms include inhibition of HMG-CoA reductase and interference with lipid absorption.
- NMN (Ξ²-nicotinamide mononucleotide)Scientific
A human clinical study (n=10 healthy volunteers) using intravenous NMN (300 mg) found a significant reduction in blood triglyceride levels alongside increased NAD+ without adverse effects on blood cells or organ markers. Oral NMN trials have shown variable effects on lipid profiles in meta-analyses.
- nobiletinScientific
Nobiletin is a polymethoxylated flavone from citrus peel with evidence for triglyceride-lowering via PPAR-alpha activation and inhibition of hepatic lipogenesis. Animal and in vitro studies are strong; emerging clinical data supports its lipid-metabolic effects in humans, particularly from its presence in Bergamot and Chen Pi (aged tangerine peel).
- nopalScientific
Human trials and meta-analyses show nopal supplementation reduces serum triglycerides in individuals with metabolic syndrome and dyslipidemia. A 2-month RCT (N=67) with a nopal-containing formula in metabolic syndrome subjects showed significant triglyceride reductions. A 2023 meta-analysis (N=1670) of ancestral Mexican foods reported significant triglyceride reductions. Short-term juice supplementation has also produced decreases in triglycerides.

- oatScientific
The evidence for oat Ξ²-glucan reducing triglycerides is mixed. A large meta-analysis of 126 studies found a small but statistically significant reduction in triglycerides with oat/barley Ξ²-glucan, while another meta-analysis of RCTs found no significant effect. Some individual studies show no change.
- oleanolic acidScientific
OA consistently reduces triglyceride levels in animal models of hyperlipidemia, metabolic syndrome, and atherosclerosis. Effects occur alongside reductions in total cholesterol and LDL, and appear mediated through PPARΞ³ and lipase activity modulation.
- oleic acidScientific
OEA, synthesised from oleic acid, is established to reduce serum triglycerides through PPAR-Ξ± activation. A 2025 systematic review and meta-analysis of RCTs on OEA supplementation found significant triglyceride-lowering effects. High-oleic oil dietary interventions also show reductions in serum triglycerides compared to saturated fat diets.
- oliveScientific
OLE supplementation significantly reduces circulating triglycerides in human RCTs. A 2022 meta-analysis found OLE reduced triglycerides by a WMD of β9.51 mg/dL overall and by β14.42 mg/dL in hypertensive patients. These effects are consistent across subgroup analyses in normal-weight individuals and those with elevated baseline lipids.
- olive oilScientific
Olive oil, a cornerstone of the Mediterranean diet, reduces triglycerides through its high MUFA content (oleic acid) and polyphenols. Multiple RCTs and meta-analyses confirm TG reduction with regular olive oil consumption. The PREDIMED trial (n=7,447) confirmed lipid benefits of olive oil in high-cardiovascular-risk individuals.
- omega-3 fatty acidsScientific
Omega-3 fatty acids (EPA and DHA from marine sources; ALA from plant sources) have strong scientific evidence for lowering triglycerides. Marine omega-3s at 2β4 g/day reduce serum triglycerides by 20β50% in clinical trials. This is recognized by the American Heart Association and multiple clinical guidelines.
- omega-6 fatty acidsScientific
Omega-6 PUFA, particularly linoleic acid substituting for carbohydrates or saturated fats, reduces triglyceride levels in controlled feeding trials. However, Cochrane meta-analyses of supplementation trials find that increasing omega-6 intake alone makes little or no independent difference to serum triglycerides compared to control diets. The triglyceride-lowering effect is context-dependent and weaker than that of omega-3 PUFAs.
- omega-7 fatty acidsScientific
Purified palmitoleic acid has been shown in at least one randomized placebo-controlled trial to reduce serum triglycerides. The Bernstein et al. (2014) RCT reported approximately 15% triglyceride reduction with 210 mg/day over 30 days in hyperlipidemic adults. Interventional studies using macadamia nut oil (a dietary omega-7 source) have also reported LDL reductions and HDL increases, though not all trials replicate these findings.
- omega-9 fatty acidsScientific
Diets enriched with oleic acid (omega-9) are associated with lower triglyceride levels compared to high-saturated-fat or high-refined-carbohydrate diets. OA reduces hepatic VLDL triglyceride secretion and promotes fatty acid oxidation. Evidence comes primarily from Mediterranean dietary intervention studies rather than isolated OA supplementation trials.
- onionScientific
Meta-analysis of 10 RCTs found that onion supplementation did not significantly lower triglyceride levels overall, though individual studies show reductions in animal models and some human contexts. The experimental evidence in diabetic animal models is more consistently positive. The overall clinical picture for triglyceride lowering is mixed.
- ophiopogonScientific
Multiple preclinical studies show that O. japonicus polysaccharides and oligosaccharides reduce serum triglyceride levels in diabetic animal models alongside their hypoglycemic effects. MDG-1 at 300 mg/kg significantly decreased triglycerides in KKAy diabetic mice over 12 weeks.
- ophiopogon rootScientific
MDG-1 polysaccharide from ophiopogon root significantly reduced serum triglycerides in diabetic KKAy mice in a 12-week study. Oligosaccharides of O. japonicus have also shown hypolipidemic effects including triglyceride reduction in preclinical models. These are peer-reviewed animal findings without human clinical trial confirmation.
- orangeScientific
Orange-derived hesperidin and blood orange anthocyanins have been associated with reductions in serum triglycerides in pre-clinical models and some clinical studies. The 2019 hesperidin meta-analysis found no significant pooled effect on triglycerides, but animal and certain human data show triglyceride-lowering activity, particularly in metabolically compromised individuals.
- oryzaScientific
Gamma-oryzanol from Oryza sativa rice bran has been shown to lower serum triglycerides in clinical and preclinical studies. Black rice extract, pigmented rice varieties, and rice bran oil have all demonstrated triglyceride-lowering effects in rodent models.
- oyster mushroomScientific
Human trials, including a 2020 systematic review of 8 studies, show that oyster mushroom intake reduces serum triglycerides. Reductions of 9β28% were observed across feeding periods, with partial reversal during washout. A dedicated GLP-1/IGT RCT found lower postprandial NEFA concentrations (a triglyceride-linked lipid marker) after oyster mushroom powder fortification.
- palm oilScientific
Meta-analyses of clinical trials consistently find that palm oil consumption has no significant effect on serum triglyceride concentrations compared to both unsaturated fatty acids and trans fats. Palm TRF supplementation in animal models has also shown triglyceride-lowering effects, though robust human-specific triglyceride data from supplementation trials remain limited.
- palmitic acidScientific
Palmitic acid is both a major constituent of circulating triglycerides and a driver of de novo lipogenesis-derived triglyceride production. Clinical studies show that diets enriched in palmitic acid can alter postprandial triglyceride-rich lipoprotein profiles, increasing proatherogenic remnant particles. Palmitic acid's role in hepatic triglyceride accumulation underpins its central involvement in NAFLD pathogenesis.
- palmitoleic acidScientific
Human RCTs and meta-analyses of macadamia/POA-rich supplement interventions consistently show significant reductions in serum triglycerides. A 30-day RCT with 220 mg/day purified POA produced a β30.2 mg/dL reduction in triglycerides versus placebo.
- pantethineScientific
Pantethine is a derivative of pantothenic acid (vitamin B5) used clinically to reduce plasma triglycerides and increase HDL cholesterol. Multiple clinical studies and a well-cited use as a pharmacological lipid agent support its TG-lowering efficacy via inhibition of hepatic acetyl-CoA carboxylase and fatty acid synthesis.
- papayaScientific
In multiple animal models of hyperlipidemia, papaya extracts (seed, leaf, juice) significantly reduced serum triglycerides. A rat study with papaya leaf extract showed a significant reduction in triglyceride plasma concentrations at 0.75 and 1.5 g/100 mL doses. Proposed mechanisms include inhibition of lipid-hydrolyzing enzymes in the small intestine and AMPK activation.
- peaScientific
Pea-derived bioactive peptides and pea protein isolate have been shown to reduce plasma triglycerides and VLDL in animal studies. A 2025 review confirmed triglyceride-lowering as part of pea's lipid-modulating profile. Human-specific RCT evidence is emerging.
- peachScientific
Peach leaf extract and polyphenol-rich peach juice by-products significantly lowered serum triglycerides in multiple animal models. The hypolipidemic effect is attributed to phenolic compounds including chlorogenic acid and flavonols. Human evidence is absent.
- peanutScientific
Multiple RCTs and a meta-analysis of 9 studies demonstrate that peanut consumption reduces blood triglyceride levels. The effect is greater in healthy subjects than in those at high metabolic risk. Reductions are most consistent with regular peanuts and peanut butter rather than high-oleic variants.
- pearScientific
Animal studies using pear pomace soluble dietary fiber demonstrate significant reductions in serum and hepatic triglycerides in high-fat-diet models. Pear fiber improves lipid metabolism via gut microbiota modulation and regulation of hepatic lipid-metabolizing pathways. Human evidence is indirect, from dietary fiber and polyphenol research.
- pectinScientific
Pectin supplementation has shown significant reductions in serum triglycerides in multiple human and animal trials. The mechanism involves reduced VLDL secretion, decreased intestinal fat absorption, and microbiota-mediated lipid metabolism improvements.
- perillaScientific
Perilla seed oil, high in alpha-linolenic acid (~57%), significantly reduced triglyceride levels in hyperlipidemic animal models. A 12-month human RCT with perilla seed oil in Japanese seniors showed significant reductions in plasma triglycerides as part of its cognitive/metabolic effects. ALA from perilla oil modulates hepatic lipid metabolism.
- phellodendron amurenseScientific
Multiple clinical trials show berberine from P. amurense significantly lowers serum triglycerides in diabetic and osteoarthritic populations. A 2025 meta-analysis of RCTs confirmed a weighted mean difference of β0.367 mmol/L for triglyceride reduction. An 8-week RCT with P. amurense plus citrus extract found significant triglyceride reductions in both overweight and normal-weight subjects.
- phytosterolsScientific
Multiple RCTs and meta-analyses show phytosterol supplementation significantly reduces serum triglycerides. A 2024 meta-analysis found a mean TG reduction of approximately 6.34 mg/dL, and a 2025 systematic review of RCTs in metabolic syndrome patients reported TG drops of 19β24%. Mechanistically, phytosterols reduce hepatic TG production and promote TG breakdown via lipoprotein lipase.
- picrorhiza kurroaScientific
A pilot clinical study (PMC, 2022) and a preclinical NAFLD model both show P. kurroa reduces elevated serum triglycerides. The clinical pilot treating dyslipidemia patients with 500 mg Kutaki tablets twice daily for 60β106 days showed up to 52% maximum reduction in serum triglycerides.
- plant sterolsScientific
Plant sterols demonstrate a modest but documented triglyceride-lowering effect, particularly in individuals with elevated baseline triglycerides or metabolic syndrome. A meta-analysis of 12 studies found a significant 6% TG reduction at intakes of 1.6β2.5 g/day, with more pronounced effects in those with hypertriglyceridemia. The mechanism involves reduced hepatic VLDL secretion.
- plantagoScientific
Soluble fiber from Plantago ovata (psyllium) can reduce triglycerides, particularly when consumed as part of a high-fiber diet. The 2024 meta-analysis of 29 RCTs found soluble fiber intake from Plantago specifically lowered triglycerides in subgroup analyses. Benefit is most pronounced in metabolic syndrome and diabetic populations.
- plantainScientific
A randomized clinical trial of P. major seed in NAFLD patients found significant reductions in triglycerides (P=0.001) after 12 weeks of supplementation at 2 g/day. Psyllium soluble fiber specifically lowered triglycerides in a subgroup analysis of a 2024 meta-analysis. A double-blind placebo-controlled RCT (n=125) with psyllium in type 2 diabetes also found significant triglyceride reduction.
- platycodonScientific
Platycodon saponins and fermented PG extracts consistently reduce serum triglyceride levels in high-fat-diet animal models. One human RCT demonstrated lipid-lowering effects in obese adults. Platycodin D inhibits intracellular triglyceride accumulation and intestinal fat absorption.
- platycodon rootScientific
Preclinical studies consistently demonstrate that platycodon root saponins lower serum and liver triglycerides in hyperlipidemic and diabetic animal models. In a 1996 rat study, a 5% platycodon diet significantly decreased serum and liver triglyceride concentrations. Platycodin D reduces serum TG via the AMPK/ACC/CPT-1 fatty acid metabolism pathway.
- pomegranateScientific
Clinical evidence is mixed: a systematic review found pomegranate can reduce triglycerides in metabolic syndrome contexts, while RxList notes pomegranate seed oil (not juice) may preferentially improve triglycerides. A 2025 cardiometabolic meta-analysis found reductions in total cholesterol but did not separately identify a robust TG effect. Most positive TG data come from higher-risk populations.
- pomeloScientific
Multiple preclinical studies show pomelo extract and its naringin constituent significantly lower serum triglycerides. One rat study showed TG reductions of 21β27% from pomelo concentrate. Pomelo flavonoids inhibit hepatic apolipoprotein B secretion and pancreatic lipase activity, reducing fat absorption and de novo lipogenesis.
- prickly pear cactusScientific
Human pilot trials show Opuntia cladode and fruit consumption can reduce serum triglycerides, with one RCT reporting a 12% decrease. Animal and cell studies further support inhibition of hepatic triglyceride accumulation. Evidence is preliminary but consistent across multiple study types.
- privetScientific
Animal studies document that FLL supplementation reduces serum triglyceride levels in laying hens, and preclinical reviews identify lipid-lowering activity including triglyceride reduction as a pharmacological property. No human trials exist.
- propionic acidScientific
Propionate suppresses hepatic lipogenesis and reduces hepatic triglyceride levels in rodent high-fat diet models and is associated with lower intrahepatocellular lipid in humans receiving long-term colonic propionate delivery. A 7-week human RCT found sodium propionate supplementation raised serum triglyceride levels by 16.7%, highlighting complexity and context-dependency of these effects. Propionate enhances adipose tissue LPL-mediated triglyceride extraction, influencing systemic triglyceride handling.
- prunusScientific
Prunus domestica intake has been investigated in RCTs measuring full lipid panels including triglycerides. Studies in hypercholesterolemic subjects and postmenopausal women using prune consumption protocols measured triglyceride levels alongside TC and LDL-c. In vitro, P. domestica inhibits pancreatic lipase (involved in fat absorption), providing a plausible mechanism for triglyceride-lowering.
- psylliumScientific
Psyllium husk (Plantago ovata), a well-studied soluble fiber, has FDA-qualified health claims for cholesterol reduction and has also been shown in meta-analyses to modestly lower triglycerides in patients with metabolic syndrome and diabetes. Its high viscosity traps bile acids and reduces fat absorption.
- pterocarpus marsupiumScientific

One small human pilot study (postmenopausal women) found triglycerides remained stable with PSO while trending upward in controls.
- punarnavaScientific
Animal studies show that B. diffusa leaf extract at 200 mg/kg significantly reduces serum and tissue triglycerides in alloxan-diabetic rats. This antihyperlipidemic effect was observed alongside reductions in cholesterol and free fatty acids. Evidence is limited to preclinical rodent models.
- purslaneScientific
A 2023 meta-analysis of 13 RCTs found purslane significantly reduced serum triglycerides by a weighted mean difference of β16.72 mg/dL (p<0.001). A 2023 broader meta-analysis confirmed triglyceride reductions of approximately β15.8 mg/dL with doses >1 g/day. These effects are attributed to purslane's omega-3 fatty acids and hypolipidemic polysaccharides.
- pyrroloquinoline disodium saltScientific
A randomized, double-blind, placebo-controlled trial (n=29, 20 mg/day, 12 weeks) in healthy Japanese adults with elevated triglycerides (110β300 mg/dL) specifically investigated PQQ's effects on serum TG and cholesterol. Earlier rodent data showed TG reduction following PQQ supplementation in PQQ-depleted animals.
- quercetinScientific
Quercetin, a widely distributed flavonol, has been shown in multiple meta-analyses to significantly reduce serum triglycerides and total cholesterol. It inhibits fatty acid synthesis, activates PPAR-alpha, and reduces oxidative stress. Meta-analyses confirm TG-lowering in cardiometabolic disease populations.
- quillajaScientific
In a rat model of iron-induced hepatotoxicity, Quillaja bark saponin significantly reduced elevated triglyceride (TG) levels, bringing them to 54% of the hepatotoxicity control. In vitro studies also suggest saponins interfere with intestinal lipid solubilization broadly, including triglyceride lipolysis products.
- quinoaScientific
A dose-response RCT found that 50 g/day of quinoa for 12 weeks significantly reduced serum triglycerides in overweight/obese adults (from 1.14 to 0.72 mmol/L). A meta-analysis of human studies confirmed a significant TG-lowering WMD of β0.08 mmol/L. A trial with quinoa cereal bars also reported significant TG reductions. Quinoa's fiber and bile acid-binding proteins are mechanistically linked.
- radishScientific
A preclinical study in ApoE-knockout mice on a high-cholesterol diet found that white radish extract most significantly reduced triglyceride levels compared to control. Radish seed glucosinolate extract in obese mice also decreased serum triglycerides. No human trials have specifically assessed this effect.
- red cloverScientific
Several RCTs and a meta-analysis indicate that red clover isoflavones can reduce triglyceride levels, particularly in postmenopausal women. A crossover RCT of 60 postmenopausal women (80 mg/day for 90 days) found triglyceride levels significantly lower with red clover versus placebo. A 2019 systematic review found a non-significant trend toward triglyceride reduction across pooled studies.
- red yeastScientific
Red yeast (Monascus purpureus) fermented on rice produces monacolins including monacolin K (structurally identical to lovastatin), which inhibit HMG-CoA reductase and significantly reduce triglycerides. A meta-analysis of 13 RCTs found TG reductions of β0.23 mmol/L (p<0.001) vs. placebo.
- red yeast riceScientific
Red yeast rice (Monascus purpureus fermented rice) contains monacolins including monacolin K (a natural statin), which lower LDL cholesterol and triglycerides. A meta-analysis of 13 RCTs found significant TG reductions (WMD = β0.23 mmol/L, p<0.001). A second meta-analysis of 15 high-quality RCTs showed red yeast rice was more effective than statins for TG lowering.
- rehmannia glutinosaScientific
R. glutinosa polysaccharides, oligosaccharides, and catalpol all demonstrate triglyceride-lowering effects in diabetic animal models. Methanol extracts of Rehmanniae Radix significantly inhibited serum triglycerides in STZ-induced hyperglycemic rats. Catalpol attenuated TG increases in hyperlipidemic diabetic rats (p=0.0084).
- reishi mushroomScientific
Preclinical studies consistently show reishi hot water extract reduces plasma triacylglycerols in hyperlipidaemic animal models, alongside LDL reductions. Animal studies in obese and high-fat-diet models show triglyceride normalisation linked to altered lipogenic gene expression and microbiome changes. Human evidence from RCTs is limited β the Cochrane review found no significant triglyceride reduction β but traditional use and preclinical data support this link.
- resveratrolScientific
Resveratrol, a stilbenoid polyphenol from red grapes and Polygonum cuspidatum, has been shown in multiple meta-analyses of RCTs to significantly reduce serum triglycerides. It activates SIRT1 and AMPK, inhibiting lipogenic pathways and promoting fatty acid oxidation.
- robusta coffeeScientific
In a comparative rodent model, both arabica and robusta coffee supplementation reduced liver triglyceride content in type-2 diabetic rats, with robusta additionally raising plasma adiponectin and HDL. A clinical RCT in PCOS patients given green coffee supplement showed significant decreases in serum triglycerides (p<0.05). Chlorogenic acids from coffee have been documented to significantly inhibit increases in serum lipid levels in animal models.
- rosmarinic acidScientific
Rosmarinic acid has demonstrated triglyceride-lowering effects in preclinical lipid models. In high-fat-diet-fed mice, RA treatment significantly decreased plasma triglyceride levels alongside total cholesterol reduction, via modulation of reverse cholesterol transport and lipid metabolism genes in liver. In HepG2 hepatocyte models, RA also countered oleic acid-induced triglyceride accumulation.
- royal jellyScientific
Evidence on RJ and triglycerides is mixed. A 2017 meta-analysis of 6 human trials found no significant triglyceride reduction. A 2023 dose-response meta-analysis of 8 RCTs found RJ significantly reduced triglycerides (WMD β12.65 mg/dL). Individual trials are inconsistent, and effects may depend on dose and population.
- ryeScientific
In the SYSDIET randomized study, higher whole-grain rye intake (indexed by alkylresorcinol ratio) was inversely associated with plasma triglyceride concentrations in metabolic syndrome patients. Rye's fermentable fiber generates propionate, which can inhibit hepatic lipogenesis. The effect on triglycerides is modest and less consistently observed than LDL effects.
- safflowerScientific
Safflower oil reduced triglycerides versus butter and beef fat in a large meta-analysis of human trials. Animal studies with safflower flower extract also showed significant reductions in serum triglycerides, including in a type 2 diabetes rat model. The high polyunsaturated fat content is the primary mechanism.
- sageScientific
Clinical RCTs in hyperlipidemic and diabetic patients report significant triglyceride reductions with sage leaf extract. A 2025 placebo-controlled RCT in PCOS patients also confirmed reduced triglyceride levels. Sage inhibits pancreatic lipase and activates PPARΞ³, reducing triglyceride synthesis and absorption.
- schisandrinsScientific
Schisandrins decrease triglyceride and total cholesterol levels in preclinical models, and a small 12-week RCT in 28 women showed Schisandra supplementation (6.7 g/day) supported healthier triglyceride levels versus placebo. Human evidence is limited to this single underpowered trial.
- secoisolariciresinol diglucosideScientific
SDG reduces hepatic and serum triglycerides in multiple rodent obesity and metabolic disease models by downregulating lipid synthesis genes and upregulating lipid oxidation pathways. A high-fat diet containing 1.0% SDG significantly decreased liver TAG and serum TAG in C57BL/6 mice. A human RCT with 60 mg SDG/day found a trend toward TG reduction, though statistical significance for TG specifically was not reached after multiple comparison correction.
- sesameScientific
Sesame consistently reduces triglycerides across multiple clinical trials and meta-analyses. A 2016 meta-analysis found a significant reduction in serum triglycerides (β0.24 mmol/L), and a 2023 crossover RCT in 30 healthy volunteers showed sesame meal extract reduced postprandial triglyceride AUC by 16.8%. Effects are attributed to pancreatic lipase inhibition by free fatty acids (linoleic, oleic acid) and hepatic lipid metabolism modulation by sesamin.
- shiitake mushroomScientific
Multiple studies show shiitake supplementation lowers plasma triglycerides (triacylglycerols). A rat study found a 55% reduction in plasma TAG on a high-fat diet with high-dose shiitake. A human RCT in borderline-high-cholesterol adults also reported triglyceride reductions. Beta-glucans promoting fecal fat excretion are a proposed mechanism.
- sichuan pepperScientific
Animal studies show Z. bungeanum seed oil and HAS reduce serum triglycerides in high-fat-diet models. Lipid-lowering activity is listed among the primary pharmacological activities of Z. bungeanum in multiple systematic reviews. Human-specific data are from broader spicy-food studies.
- silymarinScientific
Silymarin, the flavonolignan complex from milk thistle (Silybum marianum), has been shown in RCTs and meta-analyses to reduce triglycerides in NAFLD and T2D patients. The silymarin-berberine combination shows particularly strong TG-lowering in meta-analysis.
- sitostanolScientific
Evidence from pooled analyses of randomised controlled trials shows that plant stanols (principally sitostanol) reduce serum triglycerides modestly (~6%) in unselected hypercholesterolaemic subjects, and more substantially (11β28%) in individuals with elevated baseline triglycerides. The mechanism involves reduced hepatic production of large, triglyceride-rich VLDL-1 particles. A network meta-analysis of 131 trials did not find a statistically significant average effect, indicating the response is baseline-dependent.
- sophoraScientific
S. japonica extract reduced hepatic and serum triglycerides in high-fat diet animal models. Kaempferol glycosides and quercetin from the plant may decrease triglyceride levels. Preclinical evidence is consistent, though human-specific triglyceride RCTs are limited.
- soyScientific

- soy isoflavonesScientific
Soy isoflavones (genistein, daidzein, equol) have evidence from RCTs and meta-analyses for modest TG reduction, particularly in menopausal women and metabolic syndrome patients. They act via phytoestrogenic and PPAR-alpha/gamma mechanisms to modulate lipid metabolism.
- soy proteinScientific
Soy protein has an FDA-approved health claim for cardiovascular disease risk reduction, based on LDL cholesterol lowering. Multiple meta-analyses also show significant triglyceride reductions with soy protein consumption (25β50 g/day). The mechanism involves enhanced hepatic VLDL-TG clearance and reduced VLDL secretion.
- soybeanScientific
Clinical evidence indicates soy protein can reduce triglyceride levels, particularly in individuals with hypertriglyceridemia. A review of clinical studies found that soy-protein diets decrease triglycerides, especially in subjects with elevated baseline levels, though effects on HDL are minimal. One controlled trial in hyperlipidemic subjects found soy protein reduced triglycerides by 12.4%. Evidence for soy isoflavones alone on triglycerides is less consistent.
- sphaeranthus indicusScientific
Both preclinical and clinical data support triglyceride-lowering effects for S. indicus. Diabetic rat studies show significant lipid profile normalization, and a meta-analysis of RCTs in obese humans found reduced triglycerides with the Meratrim blend.
- spirulinaScientific
Spirulina (Arthrospira maxima/platensis) has been shown in multiple meta-analyses of RCTs to significantly reduce plasma triglycerides. A 2015 meta-analysis of 7 RCTs found a TG reduction of β44.2 mg/dL, and a 2023 GRADE-assessed meta-analysis of 23 studies (n=1,035) confirmed significant TG reduction (Hedge's g = β0.64).
- squaleneScientific
Human and animal data on squalene's effect on triglycerides are conflicting. One RCT reported a modest 5.3% reduction in triglycerides at 860 mg/day, while a human study using 900 mg/day found triglycerides unchanged, and multiple animal studies showed triglyceride elevations. The overall evidence does not support a reliable triglyceride-lowering effect.
- steviaScientific
One human study in women with hypercholesterolemia found stevia leaf extract reduced triglycerides alongside total cholesterol and LDL. However, a larger meta-analysis of 28 RCTs found no significant overall effect of non-nutritive sweeteners including stevia on triglycerides. A controlled trial in diabetic patients (24 weeks) showed lipid profile improvement in the diabetic subgroup. Evidence is inconsistent.
- steviol glycosidesScientific
Human RCT meta-analyses have examined triglyceride levels as an endpoint for SG supplementation. The 2019 Nutrients meta-analysis (n=462, nine RCTs) reported a non-significant increase in triglycerides favoring placebo, while animal models show SGs normalize hyperlipidemia including triglycerides. The overall clinical effect in humans is not statistically significant.
- stigmasterolScientific
Stigmasterol reduces serum and hepatic triglyceride accumulation in high-fat diet animal models, suppresses hepatic lipogenic gene expression, and prevents diet-induced elevations of specific di- and triacylglycerol species. It is more potent than Ξ²-sitosterol for these lipid endpoints in preclinical models.
- sunflowerScientific
Clinical trials in humans show sunflower oil and seeds reduce triglyceride levels, particularly when substituted for saturated fats. A 3-week study in women with type 2 diabetes consuming 30 g/day sunflower seeds observed a 12% reduction in triglycerides. High-oleic sunflower oil also reduced triglycerides in a controlled crossover trial.
- sunflower oilScientific

- turmericScientific
Turmeric (Curcuma longa) and its primary bioactive curcumin have been shown in multiple meta-analyses of RCTs to reduce triglycerides, particularly in patients with NAFLD, T2D, and metabolic syndrome. Curcumin is the primary active compound responsible for TG-lowering via PPAR-alpha activation and SREBP-1c inhibition.
- ubiquinolScientific
Clinical evidence shows CoQ10 can modestly lower triglycerides, particularly in PCOS and metabolic syndrome populations. CoQ10 has beneficial effects on lipid metabolism by upregulating PPARΞ±, which drives fatty acid Ξ²-oxidation and lipolysis. A clinical study in PCOS women found CoQ10 decreased triglycerides alongside total cholesterol and LDL while increasing HDL.
- vanadiumScientific
Human clinical trials including a 12-week trial in 60 T2DM patients on sodium metavanadate showed reductions in triglyceride levels alongside HbA1c and LDL-cholesterol.

However, one human study found vanadyl sulfate actually increased triglycerides in obese patients, indicating inconsistent human findings.
- vanadyl sulfateScientific
Human trials in type 2 diabetic patients have observed reductions in serum triglycerides with vanadyl sulfate treatment, alongside improvements in blood glucose. A systematic review of animal studies confirmed hypolipidemic effects on triglycerides across multiple vanadium compound forms. Human evidence is limited to small trials.
- vitamin B3 (niacin)Scientific
Niacin (nicotinic acid, vitamin B3) is one of the most potent agents for lowering triglycerides, with clinical use dating to 1955. It reduces triglycerides by 20β50% at pharmacological doses (1β3 g/day) and is recognized by the AHA/ACC and AACE/ACE as a treatment option for hypertriglyceridemia.
- vitamin B5Scientific
Multiple clinical trials of the B5 derivative pantethine have demonstrated significant reductions in triglyceride levels in hyperlipidemic adults. A 2005 review of 28 trials (n=646) found average triglyceride declines of 14.2% at 1 month and 32.9% at 4 months at a median dose of 900 mg/day. Pantothenic acid's role in CoA-mediated fatty acid metabolism underpins this effect.
- walnutScientific
Walnuts are rich in ALA (omega-3), polyunsaturated fatty acids, and polyphenols. Clinical trials and meta-analyses consistently show walnut consumption reduces triglycerides and improves the overall lipid profile. The AHA includes walnuts among recommended heart-healthy foods for cholesterol and TG management.
- wasabiScientific
Wasabi leaf extract reduced plasma triglycerides in animal studies, and in the diet-induced metabolic syndrome rat model, wasabi supplementation significantly decreased plasma triglycerides in high-fat diet animals. In diabetic rodents, allyl isothiocyanate also reduced triglyceride concentrations. No human clinical evidence for triglyceride reduction exists.
- watercressScientific
The Gill et al. (2007) RCT in 60 healthy adults consuming 85 g raw watercress daily for 8 weeks found approximately 10% reduction in blood triglyceride levels. The 2025 systematic review of 7 RCTs found a mean decrease in triglycerides from 107 to 105 mg/dL, while noting the placebo group experienced a significant increase, suggesting a protective effect.
- watermelonScientific
Daily watermelon consumption and lycopene supplementation have shown significant reductions in serum triglycerides in clinical trials. Effects are documented in overweight adults and heart failure patients.
- wheatScientific
Whole-grain wheat intake is associated with lower triglyceride concentrations in large prospective cohort studies. In a wheat-bran + probiotic animal study, triglycerides were reduced by 19%. RCTs of whole-grain wheat diets have not consistently demonstrated significant triglyceride reductions independent of weight change, with meta-analyses of whole-grain diets showing no significant effect on triglycerides.
- wheat grassScientific
The same 2017 RCT that documented cholesterol changes found a 9.5% reduction in triglycerides (TAGs) in hyperlipidemic women taking 3.5 g/day wheatgrass for 10 weeks (p=0.045 vs. control). Animal studies corroborate triglyceride-lowering effects of wheatgrass juice.
- whey proteinScientific
Multiple meta-analyses confirm that whey protein supplementation of β₯12 weeks significantly reduces fasting triglyceride levels, particularly in healthy adults. The Clinical Nutrition meta-analysis (21 RCTs) found a mean reduction of β8.20 mg/dL in healthy participants. A separate meta-analysis of 13 RCTs and a meta-analysis in metabolic syndrome patients (WMD: β17.12 mg/dL) corroborate this finding.
- xylooligosaccharidesScientific
The same randomized clinical trial in T2DM patients showing cholesterol reduction with XOS also showed lipid improvements, and animal studies consistently demonstrate XOS reduces serum and hepatic triglycerides. High-dose XOS in a murine MASLD model significantly reduced serum triglyceride levels and hepatic steatosis.
- yarrowScientific
The 2020 PMC rat study (STZ diabetes model) showed yarrow extract significantly reduced serum triglycerides alongside total cholesterol and LDL, with effects comparable to metformin. The evidence is preclinical only.
- yeastScientific
Brewer's yeast supplementation has been shown in at least two human trials to significantly reduce plasma triglyceride levels in type 2 diabetic patients with hypercholesterolemia. The glucose tolerance factor (GTF) chromium is the primary attributed mechanism, through improved insulin sensitivity and reduced hepatic triglyceride synthesis. Results are not consistent across all studies.
- zanthoxylumScientific
Preclinical studies across multiple Zanthoxylum species demonstrate significant triglyceride-lowering effects. Z. armatum extracts reduced serum triglycerides in diabetic mice; Z. heitzii extract prevented aortic cholesterol and triglyceride elevation in hypercholesterolemic rats; hydroxy-Ξ±-sanshool from Z. bungeanum reduced serum TG in high-fat diet rats.
- bee pollenTraditional
Bee pollen has been traditionally included in formulations aimed at dyslipidemia and cardiovascular wellness. Animal studies show lipid-lowering effects, though triglyceride-specific human evidence is lacking; one mouse study found no significant change in triacylglycerols despite reductions in cholesterol.
- bergeniaTraditional
Bergenia (Bergenia crassifolia/ligulata), known as 'pashanbheda' in Ayurveda and 'saxifrage' in European herbalism, has some preclinical and traditional evidence for lipid-lowering including TG modulation, primarily via bergenin and gallic acid content. Human clinical evidence for TG lowering specifically is limited.
- carawayTraditional
Caraway extracts reduce triglycerides in animal models, with the Springer/Mahboubi review noting 'caraway reduces plasma triglycerides and cholesterol levels.' However, human RCTs with caraway aqueous extract and Bunium persicum have not shown significant triglyceride reduction, leaving human evidence insufficient.
- champignonTraditional
Multiple animal studies demonstrate A. bisporus extract reduces serum and hepatic triglycerides in high-fat diet and diabetic models. The mechanisms involve inhibition of lipogenic transcription factors (SREBP-1c), pancreatic lipase inhibition, and upregulation of lipid oxidation via PPARΞ±. No human RCTs for triglyceride outcomes have been published.
- chromic oxideTraditional
Chromic oxide is a form of trivalent chromium used in some nutritional research, though chromium picolinate and nicotinate are more clinically studied forms. The TG evidence relates to the elemental chromium's role in insulin sensitization. Limited specific evidence for chromic oxide form; the TG evidence is extrapolated from chromium supplementation trials.
- dandelionTraditional
Dandelion (Taraxacum officinale) has traditional use in European and Asian herbalism for liver and metabolic conditions including lipid disorders. Preclinical studies show TG-lowering effects via PPAR-alpha activation and hepatic lipid modulation; clinical human data is limited but supportive.
- guggulTraditional
Guggul (Commiphora mukul resin) has been used in Ayurvedic medicine for centuries to treat medoroga (lipid disorders) and is traditionally prescribed for elevated cholesterol and triglycerides. The active guggulsterones are claimed to modulate thyroid hormone and bile acid receptor activity. Clinical RCT evidence in Western populations is inconsistent.
- guggulsteronesTraditional
Guggulsterones (E and Z isomers), the active steroids in Commiphora mukul resin, are proposed to lower triglycerides and cholesterol via bile acid receptor (FXR) antagonism and thyroid hormone modulation. Used in Ayurvedic medicine for lipid disorders, but modern RCT evidence in non-Indian populations is weak and inconsistent.
- gymnemaTraditional
Gymnema (Gymnema sylvestre), traditionally used in Ayurvedic medicine as 'gurmar' (sugar destroyer), has been studied in clinical trials for effects on blood glucose and lipids including triglycerides in diabetic patients. Gymnemic acids modulate fat and sugar absorption and may reduce TG in T2D and dyslipidemic patients.
- gymnema sylvestreTraditional
Gymnema Sylvestre has clinical trial evidence from Ayurvedic traditional medicine contexts showing reduction in triglycerides alongside blood glucose in T2D patients. Gymnemic acids reduce intestinal fat and sugar absorption. Most evidence comes from small Indian clinical studies.
- macaTraditional
Maca (Lepidium meyenii), a Peruvian root vegetable used traditionally by indigenous Andean peoples, has limited clinical evidence for triglyceride lowering. Small clinical studies suggest modest lipid improvements including TG reduction. Traditional use in Andean medicine spans centuries for energy, fertility, and metabolic health.
- policosanolTraditional
Policosanol, a mixture of long-chain aliphatic alcohols derived from sugarcane wax, has been studied for lipid-lowering effects including triglycerides. Original Cuban studies showed efficacy, but independent international RCTs have generally not replicated these findings. Its TG-lowering use is considered traditional/unverified by mainstream guidelines.
- triphalaTraditional
Triphala is a classical Ayurvedic polyherbal formula combining three fruits (Amalaki, Bibhitaki, Haritaki). Traditional use includes treatment of medoroga (fat disorders) and dyslipidemia. Clinical studies show lipid-lowering effects including TG reduction, with gallic acid, ellagic acid, and chebulinic acid as key bioactives.
