Dr. PerlmutterÍs DHA from Algae contains docosahexaenoic acid (DHA), a conditionally essential omega-3 fatty acid. DHA is highly concentrated in brain synaptosomes, the cerebral cortex, mitochondria, and retina. It plays an important role in the fluidity and permeability of cell membranes and cellular communication, and supports optimal function of the brain, eyes, and immune system. This patented, processed formula is derived from marine algae.*
