Fish oil is rich in omega-3 essential fatty acids (EFAs). EFAs are considered “good fats.” Unlike artery-clogging trans fats and saturated fats, EFAs are vital for good health. They are involved in producing new cells and repairing damaged ones. They also support health of the cardiovascular system, brain, skin, and joints.
Look for a product that has about twice as much EPA (eicosapentaenoic acid) as DHA (docosahexaenoic acid) and has been molecularly distilled to remove toxins. These essential fatty acids cannot be produced in the body, so supplements are recommended.
