Molecular hydrogen (H₂)
Evidence Summary
Hydrogen-rich water and inhaled hydrogen gas have been studied in small trials using biomarker endpoints. Delivery route changes the dose substantially, so dissolved and inhaled hydrogen are not interchangeable exposures and should not be pooled. Trials are generally too small to support claims about health outcomes.
