Combinacion de DHA con fosfatidilserina (PS-DHA)

En el último número de LE Magazine May 2006 hay una nota sobre varios suplementos para mantener las capacidades cognitivas y uno de ellos es una combinación de DHA (omega de los aceites de pescado) y fosfatidilserina (otro fosfolípido, presente en la lecitina). Parece que han logrado una forma de combinarlos de manera que actúen mejor sobre el cerebro y lo incluyeron en sus productos (supongo que Cognitex).

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 Connor’s 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
