AlphaWave® L-theanine will be compared against placebo to evaluate how the investigational study product effects on salivary cortisol, EEG readings, blood pressure, and heart rate in a moderately stressed and otherwise healthy adult population. It is hypothesized that participants taking the AlphaWave® L-theanine will have reduced stress levels as assessed by the parameters stated. Participants will be consuming the investigational study product or placebo in the clinic only.
