Molecular Hydrogen is two atoms of hydrogen combined into one molecule. It is one of the most potent antioxidants and is very effective at crossing into cells for antioxidant defense, due to its very small size. It works by targeting some of the most toxic free radicals that can otherwise cause damage to cells and the mitochondria, where we make our energy. Benefits include increased glutathione production, inflammation reduction, reduced levels of oxidative stress, and weight loss support.
