Docosahexaenoic Acid (DHA)

DHA is a long chain omega-3 polyunsaturated fatty acid derived from the tissues of oily fish and marine mammals. As far as dietary sources are concerned, the location of highest concentration seems to be within the the livers of fish. Otherwise, DHA is widely available through the ingestion of various nutritional supplements.

DHA is a potent inhibitor of the many inflammatory processes taking place regularly in the body; competing with arachidonic acid in the cyclooxygenase and lipoxygenase inflammatory pathways. [1] These enzymatic pathways are chiefly responsible for the many adverse symptoms resulting from inflammation. In fact, these two pathways are targeted by several prescription drugs. Drugs like aspirin and the newer Cox-inhibitors work to eliminate the symptoms associated with these inflammatory processes.

DHA is readily converted into eicosapentaenoic acid, another essential polyunsaturated fatty acid in humans. [2] The term ‘essential fatty acid' relates to the fact that these are a grouping of fats that are necessary for human health; their synthesis is minimal in the body and, therefore, must be obtained from diet to insure proper biochemical functioning. DHA and other long chain polyunsaturated fatty acids comprise nearly one-third of the fatty material in brain tissue. DHA has been shown to not only be a major component of brain tissue, but affects neurologic and eye development to such an extent that is has recently been included in commercial baby formulas. [3] Receiving inadequate amounts of this nutrient has been linked to impaired cognitive function, visual disturbances, and attention-deficit hyperactivity disorder (ADHD) in children.
