NCT ID NCT06898788

First seen Jul 14, 2026 · Last updated Jul 15, 2026 · Updated 1 time

Summary

This study tests whether a multi-strain probiotic called Visbiome can change brain activity and gut bacteria in people aged 15 to 24 with depression. Participants take either the probiotic or a placebo powder daily for several weeks. Researchers use brain scans and stool samples to see if the supplement affects mood-related brain circuits and the microbiome.

What this could lead to
If it works, this could point toward a new, side-effect-friendly way to help manage depression in young people by targeting the gut-brain connection.
