The special magnesium O-Dobi beads react with two water moclues to produces magnesium hydroxide and hydrogen gas.
Mg ＋ 2H2O → Mg(OH)2 ＋ H2
The Hydrogen gas isn’t very water soluble so it’s a good idea to drink the water quick to get the maximum amount of molecular hydrogen.
Mg = Magnesium Metal
H2O = Water
Mg(OH)2 = Magnesium Hydroxide (often called Milk of Magnesia)
H2 = molecular hydrogen (Hydrogen Gas)
H = Atomic Hydrogen (Active Hydrogen)
