Docosahexaenoic Acid (DHA) Supplements

Docahexaenoic acid, or DHA, is a major component of fish oil. DHA is a vital component of the phospholipids of human cellular membranes, especially those in the brain and retina. It is necessary for optimal neural development and visual acuity. DHA is the most abundant omega-3 fatty acid in human breast milk. DHA occurs naturally in the form of triacylglycerols (TAGs).

Supplemental DHA may lower triglyceride levels and in some, may elevate HDL-cholesterol levels. DHA is vital for normal brain development for the fetus and infant and for the maintenance of normal brain function throughout life. Supplemental DHA may have anti-inflammatory and immune-modulating activities.
Dosage and Administration

The amount of DHA administered to premature infants who are not breast-fed should be regulated by a pediatrician. Much of the research in adults has been based on 1-3 grams per day of DHA from fish oil, although higher levels have been taken.
