Hydrogen-Rich Water and Metabolic Health in Adults: A 12-Week Randomized Trial

Serbia40 participantsStarted 2025-04-01

Plain-language summary

The HYDRO-RESPOND trial is a 12-week randomized controlled study investigating the effects of daily hydrogen-rich water (HRW) consumption on body composition and metabolic biomarkers in adults diagnosed with metabolic syndrome. The study also explores whether individual differences in baseline breath hydrogen levels influence response to HRW. Participants are randomly assigned to receive either HRW or a placebo, with outcomes including changes in body fat, waist circumference, glucose metabolism, lipid profiles, and inflammatory markers. The trial aims to determine the therapeutic potential of HRW and identify predictors of individual responsiveness.
