Understanding Serum Triglycerides: Normal vs Optimal Ranges

Also known as: triglycerides, blood triglycerides, plasma triglycerides

Lipid PanelUnit: mg/dL

?What is Serum Triglycerides?

Serum triglycerides measure the level of triglycerides—a type of fat (lipid)—circulating in the blood. Triglycerides are the main form of dietary fat and are also synthesized by the liver. Elevated levels may be associated with increased cardiovascular risk and metabolic dysfunction.

!Why It Matters

Triglycerides are an important marker of metabolic health and cardiovascular disease risk. Elevated triglycerides can be associated with insulin resistance, obesity, and inflammation, and may suggest increased risk of heart disease and stroke. Monitoring triglyceride levels helps assess overall lipid profile and metabolic status.

Reference Ranges

Range TypeMinMaxUnitNote
Lab Normal0150mg/dLStandard lab reference range
Optimal0100mg/dLEvidence-based optimal range for health
Longevity Target0100mg/dLPer longevity medicine research (Attia et al.)

Lab normal ranges may vary between laboratories. Optimal and longevity targets are based on research literature and should be interpreted with your physician.

Symptoms of Imbalance

  • Fatigue or low energy
  • Difficulty losing weight
  • Brain fog or difficulty concentrating
  • Recurrent infections or weakened immunity
  • Shortness of breath during physical activity

How to Improve Your Levels

  • 1Reduce refined carbohydrate and added sugar intake
  • 2Increase consumption of omega-3 fatty acids from fish or plant sources
  • 3Engage in regular aerobic exercise (150 minutes per week)
  • 4Maintain a healthy weight through balanced nutrition
  • 5Limit alcohol consumption, especially sugary drinks and excess alcohol
  • 6Increase soluble fiber intake through whole grains, legumes, and vegetables

When to Test

As part of a routine lipid panel during annual health checkups, or when assessing cardiovascular risk factors. More frequent testing may be warranted if triglycerides are elevated, during weight loss programs, or when managing metabolic conditions like type 2 diabetes.
