Facts About Supplements for Heart Health

Many people take vitamins and supplements hoping they will boost their heart health. Which supplements work best? How much should you take? Here is a list of supplements that may be good for your heart.

Plant Sterols

Plant sterols (sometimes referred to as phytosterols) may help lower blood cholesterol levels by blocking cholesterol absorption in the intestine.

Coenzyme Q10

Coenzyme Q10 acts like an antioxidant, which helps protect cells from damage. Some studies show that CoQ10 supplements may lower blood pressure slightly. Some studies also show that CoQ10 supplements may help symptoms from congestive heart failure. More studies are needed. CoQ10 may also help treat muscle pain that occurs in some people who take cholesterol drugs called statins.

Fiber (Psyllium, Methylcellulose)

Fiber lowers cholesterol, as well as the overall risk of heart disease and stroke, according to many studies. Soluble fiber binds with cholesterol in the intestines and prevents it from being absorbed by the body.

Flaxseed Oil

Flaxseed and flaxseed oil may lower cholesterol levels. It’s not yet clear whether it also lowers your overall risk of heart disease.

Folic Acid

Folic acid , a B vitamin, lowers levels of the amino acid homocysteine, which has been linked to heart disease. But studies have not proven that folic acid reduces the rate of repeat heart attacks and stroke.


Magnesium helps keep blood pressure normal and is sometimes used by doctors to help correct abnormal heart rhythms.

Omega-3 Fatty Acids

Omega-3 fatty acids from fish oil can lower blood pressure and triglycerides, according to research. 

Red Yeast Rice

Red yeast rice may lower total cholesterol, triglycerides, and “bad” LDL cholesterol, according to several studies. One ingredient in red yeast rice - monacolin K - is identical to the active ingredient in a cholesterol drug. Talk with your doctor before taking red yeast rice.
