Hydrogen, the most prevalent atom in the universe, is essential to life. It’s long been known not to be harmful and is considered Generally Recognized As Safe (G.R.A.S.) by the United States Food and Drug Administration. Hydrogen has the potential to behave like a selective antioxidant and only react with the hydroxyl radical, which is common in the human body. Hydroxyl radicals cause harm in the form of oxidative stress and have no beneficial function.
Multiple studies show hydrogen gas supports homeostasis in the body by down regulating pro inflammatory cytokines. Runaway inflammation has been implicated in many chronic illnesses. Hydrogen may prove to play an important role in restoring balance to the body relative to inflammation.
