Phosphatidylserine: a new ergogenic aid?

As the margins that determine success in elite performers are ever decreasing, competitors and coaching teams are constantly searching for ways to enhance performance. Consequently, a variety of products, with purported ergogenic properties, are now extensively marketed to recreational and elite athletes. Recent data from our laboratory suggests that phosphatidylserine, a nutritional supplement that is commercially marketed as a cognitive enhancer and stress reducer, might possess ergogenic properties. The purpose of this article was to introduce phosphatidylserine as a nutritional supplement and to describe the research that led us to suggest that this supplement could be useful as an ergogenic aid.
