What Is Hydrogen Water? Hydrogen water is simply pure water with extra hydrogen molecules added to it. Hydrogen is a colorless, odorless, non-toxic gas that binds to other elements like oxygen, nitrogen, and carbon to form various compounds. Water molecules consist of two hydrogen atoms and one oxygen atom, but some assert that infusing water with additional hydrogen produces benefits that plain water cannot deliver. It’s thought that the body can’t effectively absorb the hydrogen in plain water, as it’s bound to oxygen, but when extra hydrogen is added, these hydrogen molecules are “free” and more accessible to your body.
