H2HUBB TAKEAWAY
This narrative review examined the available molecular-hydrogen literature. The biological effects of molecular hydrogen are moving beyond the traditional explanatory framework of "selective antioxidation." This article systematically integrates the basic, preclinical, and preliminary clinical evidence for hydrogen in metabolic diseases, neurodegenerative disorders, and cancer, centering on the two major themes of mitochondrial quality control and metabolic reprogramming. The reviewed evidence adds support for molecular hydrogen's therapeutic potential across the conditions, mechanisms, or outcomes examined.

What Effects Did Molecular Hydrogen Have?
Re-examining the biological properties of hydrogen reveals that characterizing it merely as an “antioxidant” is no longer sufficient to comprehensively capture its functional features. Current studies generally suggest that the biological effects of hydrogen are closely associated with the coordinated regulation of redox homeostasis, mitochondrial function, and energy metabolic networks, with mitochondria likely serving as one of its key functional hubs [ 9, 112 ]. In multiple disease models, metabolic pathways and regulators such as AMPK, Sirtuins, PGC-1α, PPARα, and fatty acid oxidation/OXPHOS have been repeatedly observed to participate in hydrogen-related effects, suggesting that hydrogen may improve cellular bioenergetic status and, to some extent, correct abnormalities in glucose and lipid metabolism by modulating the continuous process of “energy sensing–MQC–metabolic flux remodeling” [ 9, 112, 118 ]. The biological effects of molecular hydrogen are moving beyond the traditional explanatory framework of "selective antioxidation." This article systematically integrates the basic, preclinical, and preliminary clinical evidence for hydrogen in metabolic diseases, neurodegenerative disorders, and cancer, centering on the two major themes of mitochondrial quality control and metabolic reprogramming. The authors concluded that current studies indicate that hydrogen can reshape redox homeostasis, coordinate mitochondrial biogenesis, dynamic balance, and mitophagy, and modulate key signaling axes such as AMPK/Sirtuins, PGC-1α, and PPARα, aimed at optimizing mitochondrial function, thereby influencing adaptive glucose and lipid metabolism as well as cellular bioenergetic homeostasis.
