NCT ID NCT06765057

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study tests whether a daily probiotic blend (called psychobiotics) can help ease depression and improve metabolic health in adults with pre-metabolic or metabolic syndrome. Sixty participants will take either the probiotic or a placebo for 12 weeks. Researchers will measure changes in depression, anxiety, waist size, blood sugar, blood pressure, and cholesterol.

What this could lead to

If it works, this could point toward a simple, safe add-on treatment for depression in people with metabolic problems.

What could go wrong
