Summary

This trial investigates whether drinking a beverage made from 30 different organic vegetables daily for four weeks can improve gut microbiome diversity, reduce inflammation, and ease PTSD symptoms in adults diagnosed with PTSD. Participants are randomly assigned to receive either the high-diversity drink or a low-diversity drink made from three vegetables. The study measures changes in PTSD severity, gut bacteria, and markers of inflammation.
