DHA [Circulatory, Nervous]. DHA (docosahexaenoic acid) is a fatty acid that is absorbed into the fatty perimeter of cells. There it exerts its biochemical properties. Thirty percent of gray matter in the brain is composed of DHA. It is also highly concentrated in the retinal neural tissues. DHA is required for brain development and important in maintaining and protecting the neural tissues. It can only be obtained through the diet or by supplementation. Research has shown that daily dietary DHA intake is lowest among women in the United States compared to women in Europe or Japan. Supplementation with NSP DHA may help maintain the brain and support the entire nervous system. It can also benefit ocular health by improving the integrity of retinal cell membranes. Each softgel of DHA contains 250 mg DHA and 50 mg EPA in a base of fish oil and natural lemon oil to significantly reduce the aftertaste from fish oil. Take 1 softgel with a meal three times daily.
