The Effect of a Phospholipid Drink on Cognitive Performance Under Acute Stress

A Randomised, Double-blind, Parallel Groups, Placebo-controlled 6 Weeks Human Intervention Study Investigating the Effect of a Phospholipid Drink on Cognitive Performance

The study will explore the effects of a 6-week phospholipid drink intervention on the cognitive performance and physiological and subjective stress parameters of males following a repeated psychosocial/physical stressor.

The study conforms to a randomised, double-blind, placebo controlled, parallel groups design examining cognitive performance and physiological/subjective stress responses after a psychosocial/physical stressor before and after a six week daily intake of an phospholipid containing drink vs. placebo.

The study will examine:

Cognitive performance following acute stress prior to, and following 6-weeks intake of a phospholipid containing drink or a placebo analogue.

Physiological and subjective stress responses following acute stress prior to, and following 6-weeks intake of a phospholipid containing drink or a placebo analogue
