For starters, H2 is a potent selective antioxidant. This is important, as many other antioxidants, such as vitamin C and E are not selective, and when taken in excess, can be counterproductive. Hydrogen doesn't have that downside, which is one of the reasons why it's my favorite. Now, when we talk about molecular hydrogen, we are talking about the gas, the H2 molecule, which is two hydrogen atoms bound together. The H2 molecule is the smallest in the universe, which allows it to diffuse through all cell membranes, including the blood-brain barrier and subcellular compartments, and into the mitochondria. It doesn't need any transporter protein. It also has no charge or polarity. As explained by LeBaron, that's critical, because charged molecules cannot easily penetrate cell membranes. Charged molecules must go through a protein channel. All of this gives it superior cellular bioavailability. Health Benefits of H2 Among the many health benefits of H2 is its
