Detaljerad beskrivning
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
