In conclusion, the results of this study show for the first time that supplementation with hydrogen-rich pure water has beneficial effects on lipid and glucose
metabolism in humans. On the basis of these findings,we conclude that a sufficient supply of this water may prevent or delay development and progression of T2DM
and insulin resistance by providing protection against oxidative stress. However, because of the small sample of patients in this study, the results should be interpreted with caution. An appropriately designed, large-scale, prospective clinical study is therefore necessary to confirm our findings.
