A comprehensive search of PubMed, EMBASE, and Cochrane Library (up to April 2025) yielded 45 eligible studies: 25 preclinical and 20 clinical trials. Preclinical models consistently showed reductions in reactive oxygen species, inflammatory cytokines, and improved cell viability. Clinical trials reported symptomatic relief in osteoarthritis, decreased Disease Activity Score 28 in rheumatoid arthritis, and accelerated clearance of muscle damage markers. Delivery methods varied - hydrogen-rich water, gas inhalation, and saline infusion - hindering direct comparison. Mechanistic biomarkers were inconsistently reported, limiting understanding of target engagement. Common limitations included small sample sizes, short durations, and protocol heterogeneity.
