Dietary sources of omega-3 fatty acids include fish oil and certain plant/nut oils. Fish oil contains both docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), while some nuts (e.g., English walnuts) and vegetable oils (e.g., canola, soybean, flaxseed/linseed, and olive oil) contain alpha-linolenic acid (ALA). Evidence from several studies has suggested that amounts of DHA and EPA in the form of fish or fish oil supplements lowers triglycerides, slows the buildup of atherosclerotic plaques ("hardening of the arteries"), lowers blood pressure slightly, as well as reduces the risk of death, heart attack, dangerous abnormal heart rhythms, and strokes in people with known heart disease. However, high doses may have harmful effects, such as an increased risk of bleeding. Although similar benefits are proposed for alpha-linolenic acid, scientific evidence is less compelling, and beneficial effects may be less pronounced. Some species of fish carry a higher risk of environmental contamination, such as with methylmercury.

Antilipemic agent; combination consisting predominantly of ethyl esters of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

Omega-3 fatty acids are one of two groups of fatty acids—the omega-3s and the omega-6s—that are vital to human life. They are called essential fatty acids (EFAs), which the body cannot make but absolutely needs for normal growth and development. T...

Fatty acids are organic compounds composed of carbon chains of varying lengths, with an acid group on one end and hydrogen bound to all the carbons of the chain. Essential fatty acids (EFAs) are those that are necessary for health, but cannot be s...
