H2HUBB TAKEAWAY

In 30 patients with T2DM controlled by diet and exercise therapy and 6 patients with IGT, 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.

What the Researchers Studied

The study examined 30 patients with T2DM controlled by diet and exercise therapy and 6 patients with IGT.

How Molecular Hydrogen Was Used

The 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.

What the Researchers Found

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.

H₂ Mechanisms / Biological Findings

The source material reviewed did not establish a specific molecular hydrogen mechanism for the reported findings.

Authors’ Conclusion

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