Brief Summary:
Acute, randomized, placebo controlled, double blind, 4 arm crossover study to determine the effect of different combinations of plant based extracts on cognitive function and cerebral blood flow.

Condition or disease Intervention/treatment Phase
Change in Cognitive Function and Fatigue During Extended Performance of the Cognitive Demand Battery (CDB) at 1, 3 and 6 Hours Post Consumption Change in Long Term Declarative Memory at 1, 3 and 6 Hours Post-intervention. Other: Beverage containing plant based extracts Not Applicable

Detailed Description:
The objectives of this study are to assess the effects of oral consumption of three differing combinations of plant based extracts, on cognitive function and cerebral blood flow (using Near infrared Spectroscopy) in comparison to placebo. The primary outcome will be change in cognitive function and mental fatigue during extended performance of the Cognitive Demand Battery (CDB) at 1, 3 and 6 hours post- consumption.
