triglycerides
Semantic SEO entity — key topical authority signal for triglycerides in Google’s Knowledge Graph
Triglycerides are a class of lipids made of three fatty acids bound to a glycerol backbone and constitute the main form of stored energy in animals and humans. They matter clinically because elevated blood triglyceride levels are common, contribute to cardiometabolic risk, and—when very high—can precipitate pancreatitis. For content strategy, triglycerides sit at the intersection of nutrition, primary prevention, endocrinology, and pharmacology, making them a high-value topic for diet comparisons (Keto vs Low‑Carb vs Mediterranean), treatment guides, and product pages for supplements and prescription therapies.
- Biochemical composition
- One glycerol molecule esterified to three fatty acids (triacylglycerol), primary storage form of fat in adipose tissue
- Energy density
- About 9 kcal per gram (fat energy value)
- Clinical thresholds (fasting, mg/dL)
- Desirable <150 mg/dL; Borderline 150–199 mg/dL; High 200–499 mg/dL; Very high ≥500 mg/dL
- SI unit conversion
- Multiply mg/dL × 0.0113 ≈ mmol/L (e.g., 150 mg/dL ≈ 1.7 mmol/L)
- Prevalence (U.S.)
- Approximately 25–30% of U.S. adults have triglycerides ≥150 mg/dL based on NHANES-era population data
- Pancreatitis risk threshold
- Acute pancreatitis risk rises substantially when triglycerides exceed ~500 mg/dL, highest risk ≥1000 mg/dL
- Key prescription therapy with outcome data
- Icosapent ethyl (EPA) 4 g/day showed cardiovascular event reduction in the REDUCE‑IT trial
- Typical fibrate dosing
- Fenofibrate commonly 145 mg once daily; gemfibrozil 600 mg twice daily (prescribing varies)

Frequently Asked Questions
What is a normal triglyceride level?
Normal fasting triglycerides are considered under 150 mg/dL (about 1.7 mmol/L). Borderline is 150–199 mg/dL, high is 200–499 mg/dL, and very high is ≥500 mg/dL.
How can I lower triglycerides quickly?
Short‑term reductions come from stopping alcohol, cutting added sugars and refined carbs, starting aerobic exercise, and modest weight loss; prescription omega‑3 (4 g/day) and fibrates can quickly lower triglycerides when indicated. For very high levels, urgent medical treatment may be required to prevent pancreatitis.
Do triglycerides cause heart disease?
Elevated triglycerides are associated with increased cardiovascular risk, but part of the risk is mediated through related abnormalities (low HDL, insulin resistance). Recent trials show certain triglyceride‑lowering therapies (e.g., icosapent ethyl) can reduce CV events in select patients, supporting a causal role in some contexts.
Are triglycerides the same as cholesterol?
No. Triglycerides are neutral fats used for energy storage, while cholesterol is a sterol used for cell membranes and steroid synthesis. Both travel in blood within lipoproteins and both influence cardiovascular risk, but they are different molecules with different metabolic roles.
Does a ketogenic diet raise or lower triglycerides?
Most people on well‑formulated ketogenic or low‑carbohydrate diets experience substantial reductions in triglycerides due to decreased hepatic VLDL production; however, individual responses vary and some people may see increases if they consume excessive refined fats or have underlying metabolic/genetic factors.
Should I fast before a triglyceride test?
Many labs and guidelines now accept nonfasting triglyceride measurements for routine screening because they predict cardiovascular risk well. However, fasting may still be recommended if prior nonfasting results are very high or if your clinician wants a clearer baseline.
Which medications lower triglycerides?
Fibrates (fenofibrate, gemfibrozil) and high‑dose prescription omega‑3 fatty acids (e.g., icosapent ethyl 4 g/day) are the most targeted TG‑lowering drugs; statins lower TG modestly and are used for LDL and overall CV risk management. Treatment choice depends on TG level, CV risk, and comorbidities.
What foods raise triglycerides?
Foods high in refined carbohydrates, added sugars (especially fructose), excessive alcohol, and trans fats raise triglycerides. Replacing these with whole grains, fiber, lean protein, and healthy fats (monounsaturated and omega‑3s) helps reduce levels.
