Docosahexaenoic acid (DHA) and Eicosapentaenoic acid (EPA) are Omega-3 fatty acids found in Fish Oil. EPA is also in vegitarian sources such as seaweed, and the Omega-3 in flax oil can be converted to DHA and EPA in your body, but after age 35 this conversion becomes less efficient.

Our bodies naturally produce small amounts of DHA, but more is needed from diet or supplements.

According to most studies, fish or fish oil can significantly reduce the risk of heart disease and stroke, reduce high triglyceride levels, raise HDL ("good") cholesterol levels, thin the blood, lower levels of homocysteine, and possibly reducing blood pressure. Fish oil can also stimulate the oxidation (or the "burning") of fat.
