Hydrogen water tested as a Weight-Loss aid
NCT ID NCT07410065
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether drinking hydrogen-rich water every day can help adults who are overweight improve their body composition and metabolism. Researchers will compare hydrogen water to plain water in 120 participants over a period of time. The goal is to see if this simple drink can be a safe, non-drug option for weight management.
