DHA

DHA (docosahexanoic acid) is an omega-3 fatty acid, which are beneficial as they have shown in research to provide fluidity to cell membranes and improve communication between brain cells.

The compound in particular plays an important role in cerebral development, especially during the period of fetal development and infancy.

Pregnant mothers transfer DHA directly to the fetus to support rapid brain and retina development. The compound is also supplied to the newborn baby from mother's breast milk.

In research it has been suggested that Omega-3 fatty acids provide reduced risk for heart disease, heart arrhythmias, mental decline, and may help to reduce symptoms of arthritis and several autoimmune conditions.

Research also suggests that it is important to provide a correct, balanced ratio of omega-3 and omega-6 fatty acids in the diet.

If choosing DHA or other Omega-3 fatty acid products for consumption as supplements, it is important to choose a product that has undergone processing called molecular distillation which removes heavy metals, PCBs, and contaminants from the product.
