The goal of this clinical trial is to examine the effects of caffeine, theanine and tyrosine ingestion on markers of stress in healthy college aged individuals that are exposed to a mental stress task. The main questions to answer are: 1. what is the impact of a mental stress task involving a cognitive challenge and virtual reality based active shooter scenario on markers of subjective and biological stress? 2. what is the impact of supplement ingestion (caffeine, theanine, tyrosine, analyzed separately) 40 min prior to exposure to the mental stress task?
