What molecular hydrogen is, how it gets into your water, what the numbers mean and what the research actually looks at. Five minutes, no jargon.
Molecular hydrogen, written H₂, is simply two hydrogen atoms bonded together. It’s the smallest and lightest molecule in the universe: a gas with no colour, no smell and no taste.
Hydrogen water is ordinary water with extra H₂ dissolved in it. It looks and tastes like plain water. The difference is what’s dissolved in it.
It’s not the same as the hydrogen already locked inside water (H₂O, where it’s bonded to oxygen), and it’s not alkaline water. Researchers point to the dissolved H₂ itself as the ingredient that matters.
H2Molecular hydrogen
Hydrogen gas has to be made fresh and dissolved into the water. There are two practical ways to do that at home.
Tablets
Hydrogen tablets usually work with magnesium: drop one in water and the magnesium reacts with the water and the tablet’s food acids, releasing hydrogen gas that dissolves as it fizzes. Each OG Hydro tablet is made to generate 8 ppm of molecular hydrogen.
Bottle
A small electric current splits a little of the water: hydrogen forms at one electrode, oxygen at the other. In the OG Hydro Bottle a DuPont N117 membrane keeps the two sides apart, and each brew reaches up to 5 ppm in the sealed chamber.
ppm
1 ppm
= 1 mg of H₂ per litre
Parts per million is how much hydrogen is dissolved in the water. It’s the number to look for on any hydrogen product, and it drops the longer the water sits.
ORP
−500 mV
Oxidation-reduction potential
A quick reading of whether water tends to give or take electrons. Negative means reducing, which is what dissolved hydrogen does. A handy sign hydrogen is there, not a measure of any health effect.
Per serving
8 vs 5
ppm per tablet · per brew (peak)
Each tablet is made to generate 8 ppm. The bottle reaches up to 5 ppm, a peak under pressure in the sealed chamber. Either way, drinking it fresh is what keeps the most in your glass.
Hydrogen is so small it slowly escapes through the water’s surface, and even through many plastics. Japan’s consumer agency measured how fast in 2016:
That’s why we say drink a tablet within about 8 minutes, and drink the bottle’s water soon after it brews.
How long hydrogen lastsMolecular hydrogen is a growing field of research. Many studies so far are small, short or done in cells or animals, so they’re a reason to be curious, not proof of what it will do for you.
