“In a study appearing in the American Journal of Clinical Medicine176 adults with normal memory function and generally poor dietary intakes of DHA were placed on a DHA supplement for six months. Their memory function was evaluated at the beginning of the trial, and at its conclusion. In both males and females, there was a marked increase in memory function comparing those that were given DHA versus those who received a placebo pill.
