Do I need a Triglycerides test?
Struggling with weight gain, low energy, or worried about your heart health?
Triglycerides are a type of fat in your blood that reveals how efficiently your body stores and uses energy. High levels can signal increased risk for heart disease and metabolic issues.
Testing your triglycerides gives you a vital snapshot of your cardiovascular health and metabolic function. It's the essential first step to creating a personalized plan that addresses your weight concerns, boosts your energy, and protects your heart for the long term.
Get tested with Superpower
If you’ve been postponing blood testing for years or feel frustrated by doctor appointments and limited lab panels, you are not alone. Standard healthcare is often reactive, focusing on testing only after symptoms appear or leaving patients in the dark.
Superpower flips that approach. We give you full insight into your body with over 100 biomarkers, personalized action plans, long-term tracking, and answers to your questions, so you can stay ahead of any health issues.
With physician-reviewed results, CLIA-certified labs, and the option for at-home blood draws, Superpower is designed for people who want clarity, convenience, and real accountability - all in one place.
Key benefits of Triglycerides testing
- Reveals your heart disease and stroke risk from stored blood fats.
- Flags metabolic syndrome early, before diabetes or cardiovascular disease develops.
- Explains fatigue, brain fog, or weight gain tied to insulin resistance.
- Guides diet, exercise, and medication choices to lower cardiovascular risk effectively.
- Tracks how lifestyle changes or treatments improve your metabolic health over time.
- Clarifies pancreatitis risk when levels climb dangerously high (above 500 mg/dL).
- Best interpreted with HDL and LDL cholesterol for complete cardiovascular insight.
What is Triglycerides?
Triglycerides are the most common type of fat circulating in your bloodstream. They are made up of three fatty acid chains attached to a glycerol backbone, which is why they're called "tri-glycerides." Your body creates them in the liver and intestines from the fats and carbohydrates you eat, especially sugars and starches that aren't immediately needed for energy.
Your body's portable fuel reserve
Triglycerides serve as your primary energy storage molecule. After a meal, excess calories are packaged into triglycerides and stored in fat cells (adipocytes) throughout your body. When you need energy between meals or during physical activity, hormones signal these fat cells to release triglycerides back into the bloodstream.
A window into fat and sugar metabolism
Measuring triglycerides in your blood reveals how efficiently your body processes dietary fats and carbohydrates. The level reflects the balance between how much fat you're consuming or producing and how quickly your cells are using it for fuel. This makes triglycerides a key marker of metabolic health and energy balance.
Why is Triglycerides important?
Triglycerides are the body's primary circulating fat, shuttling energy from meals to cells and storing excess calories in adipose tissue. They reflect how efficiently your metabolism handles dietary fat and carbohydrate, and elevated levels directly accelerate atherosclerosis, increasing risk for heart attack, stroke, and pancreatitis. Normal fasting values sit below 150 mg/dL, with optimal levels closer to 100 or less.
When triglycerides run too low
Values below 50 are uncommon outside of malnutrition, malabsorption syndromes, or hyperthyroidism. Very low triglycerides may signal inadequate calorie intake, chronic illness, or rare genetic lipid disorders. Most people tolerate low levels without symptoms, though severe depletion can impair fat-soluble vitamin absorption and energy reserves.
When triglycerides climb above normal
Levels above 150 indicate impaired fat clearance, often driven by insulin resistance, excess sugar or alcohol intake, obesity, or genetic predisposition. Moderately high values thicken arterial walls and promote plaque formation. Severe elevation beyond 500 raises acute pancreatitis risk, causing sudden abdominal pain and systemic inflammation. Women may see triglycerides rise during pregnancy and with oral contraceptives, while men typically show higher baseline levels.
The metabolic ripple effect
Triglycerides serve as a metabolic barometer, linking diet, insulin sensitivity, liver function, and cardiovascular fate. Persistently high levels often travel with low HDL cholesterol and small, dense LDL particles, amplifying long-term vascular damage and metabolic syndrome progression.
What do my Triglycerides results mean?
Low triglycerides
Low values usually reflect efficient fat clearance or reduced dietary fat intake and absorption. Very low levels may occasionally signal malnutrition, malabsorption syndromes affecting the gut, or rare genetic lipid disorders. In some cases, an overactive thyroid gland speeds metabolism and lowers circulating triglycerides. Low values are generally not a clinical concern unless accompanied by other signs of nutrient deficiency or systemic illness.
Optimal triglycerides
Being in range suggests balanced fat metabolism and effective clearance of dietary and liver-produced lipids from the bloodstream. Most labs define normal as below 150 mg/dL, though optimal cardiovascular health is associated with levels well below that threshold, often under 100 mg/dL. Staying in the lower portion of the reference range reflects stable insulin signaling, healthy liver function, and lower risk for metabolic and vascular complications.
High triglycerides
High values usually reflect excess calorie intake, insulin resistance, or impaired clearance of fat particles from the blood. Elevated triglycerides often accompany metabolic syndrome, type 2 diabetes, obesity, and fatty liver. They can also rise with excess alcohol, certain medications, untreated hypothyroidism, or kidney disease. Very high levels increase the risk of pancreatitis and contribute to cardiovascular disease through effects on cholesterol particles and inflammation.
Notes on interpretation
Triglycerides fluctuate significantly with recent food intake, so fasting samples are preferred. Pregnancy, acute illness, and some medications can temporarily elevate levels.
