Hydrogen Therapy and Type 2 Diabetes — What an Early Clinical Trial Found

A 2008 randomised, double-blind, placebo-controlled crossover trial in Nutrition Research tested hydrogen-rich water in 36 adults with type 2 diabetes or impaired glucose tolerance. Eight weeks of drinking 900 mL/day produced significant reductions in modified LDL cholesterol, small dense LDL and oxidative stress markers — and normalised the glucose tolerance test in 4 of 6 patients with impaired glucose tolerance.
