Docosahexaenoic Acid (DHA)

Docosahexaenoic (or docosahexanoic) acid (DHA), one of the omega-3 fatty acids, appears to possess beneficial influences on human visual function and may be important in the infant diet. The triple long-chain polyunsaturated fatty acid DHA is one of the least saturated fatty acids in the human body, and is highly enriched in the membrane lipids of rod photoreceptors in the human eye, but also concentrates in the brain. Docosahexaenoic acid, sometimes referred to by nutritionists as "brain oil," is one of the primary structural components of brain tissues, which are 60 percent fats.
