Molecular hydrogen benefits: Currently, there's not much solid evidence on the benefits of molecular hydrogen, but it does possess antioxidant effects and has an established use in deep-sea diving.
Molecular hydrogen drawbacks: Molecular hydrogen seems to be well-tolerated for most people, but further research is needed. Certain administration methods carry unique risks, like the risk of explosion with hydrogen gas and the risk of infection/injury when hydrogen is injected.
Molecular hydrogen & exercise: Molecular hydrogen might reduce perceived exertion/fatigue in untrained individuals, but there's currently no clear evidence that it improves exercise performance in trained or untrained individuals.
Molecular hydrogen & metabolic disease: Molecular hydrogen has been linked to some potential benefits in preliminary research, particularly in the context of metabolic syndrome, NAFLD, and high cholesterol.
Molecular hydrogen & cancer: Molecular hydrogen might have a positive effect as an adjunct in cancer treatment. Research is very preliminary but has suggested reduced side effects of radiotherapy, reduced respiratory symptoms in lung cancer, and prolonged progression-free survival.
