There are three types of fat in the omega-3 category: ALA, EPA, and DHA, and all three play an important role in your body’s functions. ALA is abundant in nearly all diets, since it can be found in plants, grains, nuts, seeds, and oils including canola and soybean oil. EPA and DHA are found only in seafood and algae and typically require supplementation for most people to achieve optimal daily intake. Scientific evidence seems to indicate that taking EPA by itself has the most benefit for cardiovascular health, and iwi is proud to be the only natural source of stand-alone EPA available, and the only source available without a prescription!
