Summary

The effect of chronic administration of phosphatidylserine derived from brain cortex on the neuroendocrine responses to physical stress has been examined in a placebo-controlled study in 9 healthy men.

Phosphatidylserine 800 mg/d for 10 days significantly blunted the ACTH and cortisol responses to physical exercise (P=0.003 and P=0.03, respectively), without affecting the rise in plasma GH and PRL.

Physical exercise significantly increased the plasma lactate concentration both after placebo and phosphatidylserine.

The results suggest that chronic oral administration of phosphatidylserine may counteract stress-induced activation of the hypothalamo-pituitary-adrenal axis in man.
