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 significantly improves episodic memory and learning functions in healthy adults with age-related cognitive decline. This study, only 24 weeks long demonstrates the fact that DHA is well tolerated and could have a positive effect on gradual memory loss, a significant health concern among the elderly. DHA is also a key component of the cardiovascular system being required for healthy heart function, normal, healthy triglyceride levels and overall cardiovascular health.†
