Triglycerides (low)
Synopsis
Low triglyceride levels—typically defined as below 40–50 mg/dL—are less common than high levels and are often overlooked in clinical settings. While low triglycerides are generally not dangerous and may reflect a healthy lifestyle, excessively low levels can indicate malnutrition, malabsorption, hyperthyroidism, or underlying metabolic disorders. Triglycerides are essential for storing and transporting energy, supporting cellular structure, and enabling fat-soluble vitamin absorption. When levels drop too low, fatigue, weight loss, nutrient deficiencies, or hormonal issues may occur. Identifying the underlying cause is important, especially if low levels are accompanied by other abnormal lab findings or symptoms.
Types:
-
Physiological low triglycerides: Often seen in athletes or individuals on low-carb or ketogenic diets
-
Pathological hypotriglyceridemia: Linked to malnutrition, metabolic disorders, or excessive thyroid function
-
Secondary low triglycerides: Due to medical treatments, chronic illness, or substance abuse
Common Causes:
-
Low-fat or ketogenic diets
-
Prolonged fasting or calorie restriction
-
Malabsorption disorders (e.g., celiac disease, IBD)
-
Hyperthyroidism
-
Chronic infections or cancer
-
Liver dysfunction
-
Certain medications (e.g., fibrates, statins, high-dose fish oil)
Severity Causes:
-
Chronic undernutrition or eating disorders
-
Fat malabsorption leading to vitamin deficiencies
-
Overactive thyroid or adrenal imbalance
-
Genetic lipid metabolism disorders (e.g., abetalipoproteinemia)
-
Coexisting low cholesterol or abnormal liver function markers
When to See a Doctor:
-
Triglycerides consistently < 40 mg/dL without dietary cause
-
Unexplained weight loss, fatigue, or nutrient deficiency symptoms
-
Signs of malabsorption (e.g., greasy stools, bloating, nutrient loss)
-
Symptoms of hyperthyroidism (anxiety, palpitations, weight loss)
-
Abnormal liver function tests or hormonal imbalances
Natural Remedies
Omega-3 fatty acids: While often used to lower high triglycerides, they also support healthy lipid metabolism, brain function, and anti-inflammatory balance in low-triglyceride states.
Magnesium: Supports metabolic function and helps regulate thyroid and adrenal hormones, which may play a role in unexplained low triglycerides.
Vitamin C: Supports liver function and antioxidant protection, especially in cases where low triglycerides are linked to systemic inflammation or oxidative stress.
Probiotics: Improve nutrient absorption and gut integrity, especially in malabsorption-related causes of low triglycerides.
Healthy fats in diet: Incorporating nuts, seeds, avocados, and olive oil can support healthy triglyceride production and fat-soluble vitamin absorption.
Ashwagandha: Helps balance cortisol and thyroid hormone activity in cases of adrenal or metabolic imbalance potentially linked to low triglycerides.
Regular meals: Eating nutrient-dense, balanced meals can help normalize triglyceride production in cases of under-eating or energy deficit.
