H3O water refers to hydronium ions, which make water more acidic. However, stable H3O water in bottled form doesn’t naturally exist—water always rebalances to H₂O. Pure H3O isn't drinkable it's too acid, It's ionized water, without any specific features. It's a publicity trick to sell it more expensive, like also this one, low in calories.
