The present randomized, double-blind, placebo-controlled crossover trial aims to evaluate the effects of Relora supplementation on responses to induced stress produced by a combination of cognitive and physiologic stressors in healthy men and women. The effects of the supplement, compared with a placebo, will be evaluated using measures to assess anxiety [State-Trait Anxiety Inventory-Part 1 (STAI-Part 1), mood [Bond-Lader Visual Analog Scale (VAS)], hypothalamic-pituitary-adrenal axis activation (salivary cortisol) and cognitive function (cognitive flexibility, reaction time, processing speed, attention, sustained attention, working memory, and executive function). Testing will be completed at the beginning and end of 7-d supplementation periods with the active and placebo products to assess both the acute effects and the "acute-on-chronic" effects following one week of daily use.

This study will investigate the effect of two different doses of 7-Keto compared to placebo on resting metabolic rate. One third of subjects will be given the lower 7-Keto dose, one third will be given the higher 7-Keto dose and one third will be given the placebo.
