The effects of phosphatidylserine on the endocrine response to moderate-intensity exercise

The aim of this study was to investigate the effect of short-term supplementation with a moderate dose of PS (600 mg per day) on plasma concentrations of cortisol, lactate, growth hormone, and testosterone before, during, and after moderate-intensity exercise in healthy men.

10 healthy male subjects participated in the study. Each subject was assigned to take 600 mg of PS or placebo per day for 10 days, using a double-blind, placebo-controlled crossover design. Serial venous blood samples were collected.

The results suggest that PS is an effective supplement for combating exercise-induced stress and preventing the physiological deterioration that can accompany excessive exercise. PS supplementation promotes a desirable hormonal status for athletes by attenuating the increase in cortisol levels.
