NCT ID NCT06968715
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether drinking hydrogen-rich water every day for 12 weeks can improve body composition and metabolic health in adults with metabolic syndrome. 40 adults participated, and researchers measured changes in waist size, body fat, blood sugar, and cholesterol. The goal was to see if this simple drink could help control the condition and identify who might benefit most.
