molecular hydrogen water improves lipid and glucose metabolism in patients with TYPE 2 DIABETES or impaired glucose tolerance

Supplementation of molecular hydrogen-rich water improves lipid and glucose metabolism in patients with type 2 diabetes or impaired glucose tolerance.

It is well established that molecular hydrogen (water) has a selective oxidation/free radical reducing action.

Oxidative stress is recognized widely as being associated with various disorders including diabetes, hypertension, and atherosclerosis.

We therefore investigated the effects of molecular hydrogen-rich water intake on lipid and glucose metabolism in patients with either type 2 diabetes mellitus (T2DM) or impaired glucose tolerance (IGT).

We performed a randomized, double-blind, placebo-controlled, crossover study in 30 diabetes patients with T2DM controlled by diet and exercise therapy and 6 patients with IGT.

The diabetes patients consumed either 900 mL/d of  hydrogen-rich pure water or 900 mL of placebo pure water for 8 weeks, with a 12-week washout period. Several biomarkers of oxidative stress, insulin resistance, and glucose metabolism, assessed by an oral glucose tolerance test, were evaluated at baseline and at 8 weeks.

Intake of  hydrogen-rich water was associated with significant decreases in the levels of modified low-density lipoprotein (LDL) cholesterol (ie, modifications that increase the net negative charge of LDL), small dense LDL, and urinary 8-isoprostanes by 15.5% (P < .01), 5.7% (P < .05), and 6.6% (P < .05), respectively.

Hydrogen-rich water intake was also associated with a trend of decreased serum concentrations of oxidized LDL and free fatty acids, and increased plasma levels of adiponectin and extracellular-superoxide dismutase. In 4 of 6 patients with IGT, intake of molecular hydrogen-rich water normalized the oral glucose tolerance test.

In conclusion, these results suggest that supplementation with molecular hydrogen-rich water may have a beneficial role in prevention of T2DM and insulin resistance.
