The Science behind Hydrogen Water.  Dr. Rita Ellithorpe, Dr. Antonio Jimenez, and James B. Lavalle.

Izumio Water is sold pre-made in Aluminum Pouches. The H2 concentration, at production, is 2.6ppm with 200ml of water.
1 HYDRORICH Tablet in 200ml of water will achieve an H2 concentration of well over 10.0ppm. (and also contains highly absorbable Ionic Magnesium)

1 Pouch of Izumio costs about $3.50.  1 HYDRORICH Tablet costs $1. (at $60/Bottle)
