Hydrogen Water and Metabolic Syndrome — What a 24-Week Randomised Trial Showed

A 2020 randomised, double-blind, placebo-controlled trial in Diabetes, Metabolic Syndrome and Obesity tested 24 weeks of high-concentration hydrogen-rich water in 60 adults with metabolic syndrome. The hydrogen group showed significantly reduced cholesterol, glucose and HbA1c, alongside improvements in inflammation and oxidative-stress biomarkers and a mild shift toward a more favourable body composition.
