Hydrogen – Therapeutic in Wellness and Medicine

Persistent oxidative stress plays an important role in a variety of pathologies, and the search for an effective and well tolerated antioxidant agent continues. Molecular hydrogen acts as a therapeutic antioxidant by selectively reducing cytotoxic oxygen radicals. The non-specific mechanism of hydrogen as a therapeutic antioxidant gives it broad therapeutic potential across a wide range of medical applications, as has been shown by a substantial volume of preclinical data, as well as a growing body of clinical evidence. This review provides an overview of the therapeutic potential of hydrogen, in ageing and wellness applications as well as medical applications, including acute ischemia/reperfusion injury, inflammation and ulceration, metabolic disorders, neurodegenerative disorders, and cancer (anti-cancer effects, radiation toxicities, and side effects of cisplatin) with an emphasis on clinical data. Overall, this review shows that hydrogen is an effective antioxidant, anti inflammatory and cytoprotective agent.
