What is fish oil?

Fish oil essential fatty acids (omega-3 polyunsaturated fats) that can be found in certain fish, plants, nut oils, or vegetables. As these essential fatty acids are not created by the body, they must be consumed through the diet. Do not confuse omega-3 fatty acids for omega-6 fatty acids, which can be found in foods such as avocados, eggs, and sunflower seed oil.

A fish oil supplement is an excellent source of omega-3 essential fatty acids, as it supplies you with both docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA).
