Brief Summary

The objective of this study is to evaluate the efficacy of AlphaWave® L-Theanine on stress among adults who experience moderate stress on a regular basis. The difference in change in stress as assessed by salivary cortisol from baseline at Days 14 and 28 will be compared between AlphaWave® L-Theanine and Placebo groups. Additionally, the safety and tolerability of AlphaWave® L-Theanine, as compared to placebo, will be measured by the occurrence of an/or changes in pre-emergent and post-emergent adverse events (AEs).
