简要总结
The goal of this clinical trial is to to assess the efficacy AlphaWave® L-Theanine on mental acuity/cognitive function and stress relief in healthy adults with moderate stress. The main question it aims to answer is:
Is there a difference in change in mental acuity from pre- to post-dose between AlphaWave® L-Theanine and placebo?
Participants will asked to provided a single dose of one capsule of a single dose of one capsule of AlphaWave® L-Theanine or one placebo capsule with 250 ml of room temperature water, and asked to complete tasks to assess cognitive function.
