H2HUBB TAKEAWAY
This narrative review examined the current clinical experience with inhaled H₂ therapy, discusses key challenges and limitations in the existing literature, and identifies areas of interest for future research, including the development of a validated delivery system to enable broader clinical investigation and application of H₂ therapy. Published clinical findings are encouraging, although data are limited by small sample sizes, methodological variability, and the absence of standardized and validated commercially available delivery systems. The reviewed evidence adds support for molecular hydrogen's therapeutic potential across the conditions, mechanisms, or outcomes examined.
