ácido propiónico

Condiciones de salud que ácido propiónico puede ayudar a apoyar.

• AcnéCientífico

  Propionate stimulates the release of gut hormones PYY and GLP-1 from colonic L cells, which signal satiety to the brain and suppress food intake. A randomized controlled trial in 60 overweight adults using an inulin-propionate ester demonstrated that acute ingestion significantly increased postprandial PYY and GLP-1 and reduced energy intake. The mechanism operates primarily through free fatty acid receptors FFAR2 and FFAR3 expressed on enteroendocrine cells.

• Contaminación ElectromagnéticaCientífico

  Propionate has been most extensively studied as an immunomodulatory SCFA in multiple sclerosis (MS), where serum propionate levels are reduced in newly diagnosed patients relative to healthy controls. Clinical studies of propionate supplementation in MS patients show expansion of regulatory T cells and reduced pro-inflammatory Th1/Th17 responses, with reported long-term clinical improvements. Research also implicates propionate deficiency in gut dysbiosis-driven systemic immune dysregulation across autoimmune diseases.

• Fatiga SuprarrenalCientífico

  Propionate has demonstrated dose- and context-dependent effects on blood glucose in humans. In vitro and animal studies show it suppresses hepatic gluconeogenesis via GPR43/AMPK signaling. However, a randomized placebo-controlled human study found that food-preservative-level propionate consumption acutely raised glucagon and caused insulin resistance via sympathetic nervous system activation. A 7-week human RCT using 7.5 g/day sodium propionate decreased fasting serum glucose.

• Válvula IleocecalCientífico

  Propionate inhibits cholesterol biosynthesis from acetate in hepatocytes and has been shown in human trials to alter lipid profiles, including increasing HDL-C by 9.5% in a 7-week RCT. Long-term colonic propionate delivery reduced hepatic cholesterol synthesis and intrahepatocellular lipid in overweight humans. Human hepatocyte studies have found species-specific differences, with rat but not human hepatocytes showing robust direct propionate-mediated cholesterol synthesis inhibition.

• ApendicitisCientífico

  Propionate exerts anti-inflammatory effects primarily through histone deacetylase (HDAC) inhibition and modulation of NF-κB signaling, reducing pro-inflammatory cytokine production. In multiple sclerosis patients, propionate supplementation has shown immunoregulatory effects and association with long-term clinical improvement. Evidence comes from preclinical models and emerging human clinical data across multiple inflammatory conditions.

• Olor CorporalCientífico

  Propionate is a well-characterized secretagogue for GLP-1, acting through FFAR2/FFAR3 receptors on intestinal L cells. Human colonic cell models and clinical trials confirm that propionate directly stimulates GLP-1 secretion and raises circulating GLP-1 levels, contributing to postprandial satiety and reduced energy intake. This is one of the most robustly documented mechanisms linking propionate to metabolic health.

• Leche materna (secar)Científico

  Propionate is both a product of and a modulator of the gut microbiome. It is produced by Bacteroidetes, Firmicutes, and specific genera including Prevotella and Blautia through fermentation of dietary fiber. Changes in propionate production correlate with microbiome composition shifts in disease states including IBD, IBS, and metabolic conditions. Dietary propionate exposure at high levels has been shown to alter microbial community structure.

• Senos (aumentar tamaño)Científico

  Propionate is a key SCFA mediator of the gut-brain axis, crossing the blood-brain barrier to directly influence central nervous system function. It modulates neuroinflammation, hypothalamic appetite circuits, and neuropeptide expression. Human and animal evidence links gut-derived propionate to brain activity in food reward regions, neuroinflammatory states, and behavioral outputs including feeding and mood.

• Moretones (prevención)Científico

  Targeted colonic delivery of propionate via inulin-propionate ester significantly prevented weight gain and reduced intra-abdominal adipose tissue in a 24-week human RCT in overweight adults. The mechanisms include GLP-1/PYY-mediated reduction in energy intake, inhibition of hepatic lipogenesis, and improved adipose tissue lipid buffering. Chronic dietary propionate from food preservatives, at higher doses, has conversely been linked to gradual weight gain in animal models.

• PulgasCientífico

  IBS patients, particularly the diarrhea-predominant subtype, show altered SCFA profiles including propionate. A 2025 double-blind RCT found that probiotic-induced increases in propionate (alongside acetate and butyrate) correlated with reduced intestinal permeability, upregulated tight junction proteins, and decreased symptom severity across IBS subtypes. Low propionate availability is implicated in impaired gut barrier function and motility dysregulation in IBS.

• FlotadoresCientífico

  Fecal propionate levels are reduced in IBD patients. Propionate ameliorates experimental colitis in animal models by improving intestinal barrier function, reducing inflammatory cytokine production (TNF-α, IL-1β, IL-6), and regulating macrophage polarization toward anti-inflammatory phenotypes via GPR43/HDAC1/IL-10 pathways. Increasing fermentable fiber intake to promote SCFA production is considered clinically beneficial in colitis management.

• Olor de piesCientífico

  Colonic delivery of propionate at 10 g/day over 24 weeks prevented deterioration of insulin sensitivity in overweight adults in an RCT, associated with reduced circulating non-esterified fatty acids and improved pancreatic beta-cell FFAR2 signaling. A 7-week RCT also showed propionate decreased maximum insulin increments during glucose tolerance testing. However, dietary propionate at preservative doses acutely caused insulin resistance in a separate human RCT, indicating context-dependency.

• Vesícula Biliar (perezosa o extirpada)Científico

  Propionate regulates tight junction protein expression—including Occludin, Claudin-1, and ZO proteins—in intestinal epithelial cells, reducing paracellular permeability. A 2023 study identified propionate as a direct regulator of tight junction barrier function via ESAM upregulation in Caco-2 cells. A 2025 RCT in IBS patients showed that increased propionate levels correlated with improved gut barrier integrity and upregulated tight junction proteins.

• DebilidadCientífico

  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.
