Summary

This study tests whether a daily drink of freeze-dried grape powder can reduce anxiety, depression, and stress in healthy college students aged 18-30. Over 4 weeks, 50 participants will take either the grape powder or a placebo and complete surveys and stool tests. The goal is to see if the grape powder improves mood by changing gut bacteria.
