Combining DHA and Phosphatidylserine
In response to an increasing body of research showing the intricate relationship between DHA and phosphatidylserine (PS), scientists have developed a phosphatidylserine (PS)-DHA compound designed to be incorporated directly in the membranes of brain cells. The acronym for this novel compound is PS-DHA.
To evaluate the effects of PS-DHA on memory loss, a study was conducted on middle-aged rats with laboratory-induced accelerated brain aging. Administering traditional sources of DHA did not have an effect on this experimental model, but the group receiving the PS-DHA compound was able to attain a great deal of protection against this neurological challenge. When the brains of these animals were analyzed, there was more DHA incorporated in the cells of the group receiving the PS-DHA than in those receiving other omega-3 agents.3
A randomized, double-blind, placebo-controlled study of humans with attention deficit hyperactivity disorder (ADHD) was conducted using PS-DHA. The aim of the study was to improve behavioral and learning disabilities in patients with ADHD. The psychological evaluation included the Connors scoring test and computer-based analysis (T.O.V.A.). At the end of three months, the group receiving the PS-DHA showed a total response of 47% compared to only 19% in the placebo group.3
