• Triglycerides, High
  • Hypertriglyceridemia

Triglycerides are a type of fat found in the blood. High levels can add to build up of plaque and damage to blood vessels. High triglycerides are linked to health problems such as obesity and diabetes.

Healthy changes in diet and activity may help some people. Weight loss, if needed, may also help. These changes will also help overall health. Medicine called statins can also help to lower triglycerides.

Natural Therapies

Likely Effective

These supplements are likely to lower triglycerides:

May Be Effective

Flaxseed comes from the flax plant. It may lower triglycerides. E3, E4

Not Enough Data to Assess

  • Inulin C1

Herbs and Supplements to Be Used With Caution

Talk to your doctor about any supplements or therapy you would like to use. Some can interfere with treatment or make conditions worse, such as:

  • Fish oil—High doses of fish oil may interfere with blood thinners. It can also affect blood glucose levels.
  • Niacin—High-dose niacin is associated with liver inflammation. Combining high-dose niacin and statins may cause a life-threatening condition called rhabdomyolysis. Do not use niacin with carbamazepine and primidone (antiseizure drugs).
  • Cinnamon—Avoid using the cassia type of cinnamon if you have liver or kidney disease. High doses of cinnamon oil may affect the central nervous system. Talk to your doctor if you are or think you are pregnant before using cinnamon oil or bark. Do not exceed recommended doses.
