DHA is one of the omega-3 fatty acids that the body requires for a variety of important biological functions. DHA is found in very high concentrations in the brain and retina, and is therefore essential for normal, healthy brain structure/function and healthy vision. A recent study was the first to clinically demonstrate that DHA may help to support memory and learning functions in healthy adults with age-related cognitive decline. DHA is also a key component for the healthy function of the cardiovascular system. ‡
