A Systematic Review of Molecular Hydrogen Therapy in Cancer Management.

Cancer remains a challenging target to cure, with present therapeutic methods unable to exhibit restorative outcomes without causing severe negative effects. Molecular hydrogen (H2) has been reported to be a promising adjunctive therapy for cancer treatment, having the capability to induce anti-proliferative, anti-oxidative, pro-apoptotic and anti-tumoural effects. This review summarises the findings from various articles on the mechanism, treatment outcomes, and overall effectiveness of H2 therapy on cancer management.

A narrative review of hydrogen therapy for COPD: aging-related insights.

Molecular hydrogen (H) exhibits selective antioxidant, anti-inflammatory, and anti-senescence properties that may provide therapeutic benefits for chronic obstructive pulmonary disease (COPD), particularly in aging populations where oxidative stress and chronic inflammation are prominent. Given the increasing burden of aging-related COPD and the emerging biological effects of molecular hydrogen, we hypothesized that H therapy may exert beneficial effects by modulating oxidative stress, inflammation, and aging pathways. Following Ferrari's narrative review framework, PubMed and Ovid MEDLINE were searched through October 2025 for clinical and preclinical studies examining H interventions in COPD, chronic…

A randomized double-blind multi-center trial of hydrogen water for Parkinson’s disease: protocol and baseline characteristics.

Our previous randomized double-blind study showed that drinking hydrogen (H2) water for 48 weeks significantly improved the total Unified Parkinson's Disease Rating Scale (UPDRS) score of Parkinson's disease (PD) patients treated with levodopa. We aim to confirm this result using a randomized double-blind placebo-controlled multi-center trial. Changes in the total UPDRS scores from baseline to the 8(th), 24(th), 48(th), and 72(nd) weeks, and after the 8(th) week, will be evaluated.
