NCT ID NCT07377136

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether taking Urolithin A daily for 6 months helps adults with obesity lose weight while keeping muscle mass and improving metabolism. About 100 participants aged 30-60 with a BMI over 30 will follow a structured diet and sleep program, with half receiving the supplement and half a placebo. Researchers will measure body composition, muscle strength, and blood markers to see if Urolithin A offers added benefits.
