pH = “potential of hydrogen.”
It measures how acidic or basic (alkaline) a solution is, ranging from 0 to 14:
👉 When we say water is alkaline, we’re simply saying it has a pH above 7.

A lot of people hear “hydrogen” and immediately think acidity — because in chemistry, H⁺ (hydrogen ions) are what lower pH and make something acidic.
So when they see that Kangen Water® contains “hydrogen,” they assume it must be acidic or high in H⁺.
But here’s the key:
👉 Not all hydrogen is the same.
And the kind in Kangen Water® is not acidic.
H⁺ = acidity
These are hydrogen ions. They carry a positive charge and increase acidity.
These collect on the acidic water side of the machine during electrolysis.
H₂ = antioxidant gas
This is molecular hydrogen, two hydrogen atoms bonded together — completely neutral, non-acidic, and the primary antioxidant in Kangen Water®.
This is what dissolves into the alkaline drinking water after electrolysis.
In other words:
✨ Acidity = H⁺ (positive, charged, proton)
✨ Antioxidant benefit = H₂ (neutral, stable molecule)
