Most human diseases are related to oxidation and inflammation.

Hydrogen is the only antioxidant that is selective for free radicals. Hydrogen can only clear harmful free radicals, but doesn't affect the free radicals that useful to the human body, this characteristic has been called "Selective antioxidant".  Many diseases and peroxide are caused by the accumulation of peroxide in the body during the daily metabolic process. Hydrogen kills peroxide without side effects.

The greatest advantage of hydrogen's antioxidant is its selectivity. Other substances such as vitamin C can also scavenge free radicals, but without selectivity, excessive intake will also remove some of the free radicals beneficial to the human body, so there is a dose limit to vitamin intake.
