Decentralized Study to Evaluate a Dietary Supplement for Episodes of Mild Acute Stress in Healthy People
Recruiting now · Not applicable · Has a placebo group
Conditions studied: Situational Anxiety
In brief
The purpose of this decentralized, two-arm, double-blinded, crossover clinical study is to test the efficacy of a supplement to reduce symptoms of acute stress or situational anxiety in healthy volunteers. The main questions it aims to answer are: 1. Does a dietary supplement reduce feelings of anxiety after self-identified episodes of stress or anxiety when compared to their experience after taking a placebo? 2. On a scale of 1-5, how much would the volunteer like to take the assigned treatment in the future? 3. Are any adverse events identified after either treatment, supplement, or placebo? The study volunteers will: During weeks 1-2, self-identify episodes of acute stress or situational anxiety and rate feelings of anxiety over the next five hours after taking the study product assigned for Period 1. During week 3, volunteers will not take any study product nor complete any surveys. During weeks 4-5, self-identify an episode of acute stress or situational anxiety and rate feelings of anxiety over the next five hours after taking the study product assigned for Period 2.
