Effects of phosphatidylserine supplementation on exercising humans. / Michael Ian Charles Kingsley

Swansea University Author: Michael Ian Charles, Kingsley

Abstract

The aim of this research was to investigate the effects of oral soy-derived phosphatidylserine (S-PtdSer) supplementation on the physiological responses to exercise, exercise performance/capacity and recovery following exercise. The results from this research provide evidence that short-term supplem...
