The Science of Molecular Hydrogen
Explore the breakthrough studies and clinical evidence behind H₂ and its powerful role in cellular wellness, energy, and anti-aging.
What is Molecular Hydrogen (H₂)?
Molecular hydrogen (H₂) is the smallest and most bioavailable antioxidant in the universe. It can rapidly diffuse into cells and mitochondria, neutralizing harmful free radicals and reducing oxidative stress—without disturbing beneficial reactive species your body needs.
