Triglycerides
Triglycerides are the main storage form of dietary fat circulating in blood, carried on chylomicrons and VLDL particles. Elevated fasting levels often accompany insulin resistance, metabolic syndrome, type 2 diabetes, alcohol use, and high refined-carbohydrate intake. Very high levels (over 500 mg/dL) increase risk of acute pancreatitis.
Units: mg/dL; some labs report mmol/L (mmol/L = mg/dL × 0.0113). Check the units on your report before comparing to any range here.

Lipid Panel / Cardiovascular Health
What is Triglycerides?
Triglycerides are the most common type of fat in your body, serving as a major energy storage molecule. Chemically, they consist of three fatty acid chains attached to a glycerol backbone. After you eat, your body converts calories it doesn't need immediately into triglycerides, which are stored in fat cells and released later for energy between meals.
Your triglyceride levels are measured through a lipid panel blood test, typically after an 8-12 hour fast. These levels fluctuate significantly based on recent food intake, alcohol consumption, and physical activity. Unlike cholesterol, which has structural and hormonal functions, triglycerides primarily serve as energy currency in your metabolic system.
Elevated triglycerides (hypertriglyceridemia) significantly increase cardiovascular disease risk, particularly when combined with other lipid abnormalities. High levels contribute to atherosclerosis, increase small dense LDL particles, and at very high levels (>500 mg/dL) can cause acute pancreatitis. Triglycerides are highly responsive to lifestyle modifications, making them one of the most modifiable cardiovascular risk factors.

What raises or lowers Triglycerides
Causes of high Triglycerides
- Obesity
- High-carbohydrate diet
- Excessive alcohol
- Physical inactivity
- Uncontrolled diabetes
- Metabolic syndrome
- Chronic kidney disease
- Hypothyroidism
- Genetic conditions (familial hypertriglyceridemia)
- Medications (corticosteroids, beta-blockers, thiazide diuretics, estrogen, tamoxifen)
Causes of low Triglycerides
- Malnutrition
- Malabsorption disorders (celiac disease, Crohn's disease)
- Hyperthyroidism
- Chronic liver disease
- Genetic disorders (abetalipoproteinemia)
- Very low-fat diets
Symptoms when Triglycerides is high or low
When high
Usually asymptomatic until very high; at extreme levels (>1000 mg/dL): fatty deposits under skin (xanthomas), abdominal pain (pancreatitis risk), hepatomegaly (enlarged liver), lipemia retinalis (milky appearance of retinal blood vessels)
When low
Low triglycerides (<50 mg/dL) rarely cause symptoms but may indicate malabsorption, hyperthyroidism, or malnutrition
How to move Triglycerides
Effect sizes (how much something moves the marker) appear only where the paper cited under the item states them. Talk to your clinician before starting or changing any medication or supplement.
Limit Alcohol Consumption
Reduce or eliminate alcohol intake, as alcohol strongly stimulates hepatic triglyceride production. Even moderate drinking can significantly elevate triglycerides in sensitive individuals. Complete abstinence may be necessary for those with persistently elevated levels.
Regular Aerobic Exercise
Engage in 150+ minutes weekly of moderate-intensity aerobic exercise. Physical activity increases lipoprotein lipase activity, which clears triglycerides from the bloodstream. High-intensity interval training (HIIT) may be particularly effective for triglyceride reduction.
Weight Loss and Metabolic Health
Achieve and maintain healthy body weight, particularly reducing visceral fat. Even modest weight loss (5-10% of body weight) significantly lowers triglycerides. Address insulin resistance through diet, exercise, and potentially medications like metformin if appropriate.
When to retest
Retest in 2-3 months after lifestyle modifications or medication changes. If very high (>500 mg/dL), retest in 4-6 weeks. Once stable and optimal, annual testing is typically sufficient as part of routine lipid panels.
Scientific Evidence
Triglycerides and Coronary Heart Disease
In a meta-analysis of 29 Western prospective studies (262,525 participants, 10,158 coronary cases), people in the top third of triglyceride levels had higher odds of coronary heart disease than those in the bottom third (adjusted odds ratio 1.72). The association weakened after adjusting for established risk factors, so how much is independent remains uncertain.
Omega-3 Fatty Acids for High Triglycerides
An American Heart Association science advisory concludes that prescription omega-3s at 4 g/day (EPA+DHA or EPA alone) lower triglycerides by 30% or more in people with very high triglycerides (500 mg/dL or above). In REDUCE-IT, 4 g/day of EPA reduced major cardiovascular events by 25% in statin-treated high-risk patients.
Low-Carbohydrate Diets and Triglycerides
A meta-analysis of 17 trials in 1,141 people with obesity found low-carbohydrate diets lowered triglycerides by about 30 mg/dL, along with weight, blood pressure, and HbA1c. HDL rose slightly and LDL did not change. Long-term health effects are unknown.
Exercise and Triglycerides
Durstine and colleagues found that exercise burning about 1,200-2,200 kcal per week, roughly 15-20 miles of brisk walking or jogging, often lowers triglycerides by 5-38 mg/dL and raises HDL by 2-8 mg/dL. Exercise training seldom changes total or LDL cholesterol.

Weight Loss and Cardiovascular Events
Look AHEAD randomized 5,145 adults with type 2 diabetes and overweight or obesity to an intensive lifestyle program or diabetes education. The program produced more weight loss (8.6% versus 0.7% at one year) and larger early improvements in most cardiovascular risk factors, but did not reduce cardiovascular events over a median 9.6 years (hazard ratio 0.95).

Frequently Asked Questions
What is the optimal range for Triglycerides?
Published positions differ: <100 mg/dL optimal (AHA scientific statement on triglycerides (2011)); <150 mg/dL normal (NCEP ATP III (NHLBI, 2001)); Persistent ≥175 mg/dL is a risk-enhancing factor (2018 AHA/ACC cholesterol guideline). Named practitioners target: <100 mg/dL (<80 best if any risk factors) (Life Extension); 40-80 mg/dL (Tracey O'Shea (Kresser Institute)). Lab reference interval: Normal: <150 mg/dL, Borderline: 150-199, High: 200-499, Very high: ≥500. That is what a lab report flags against, not an optimal target.
