Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are two types of omega-3 fatty acids. EPA and DHA have been shown to confer health benefits in humans by supporting heart, brain, and eye health.* EPA and DHA omega-3s are naturally found in oily fish like salmon, halibut, sardines, and anchovies. Aside from fish, there are extremely few food sources that naturally provide EPA and DHA. And while the body can synthesize EPA and DHA in very small amounts, supplementation is helpful to get the proper amounts.
