When is ORP an antioxidant.. and when is it not?

Our friend Webb Norfleet is a regular contributor to the Facebook Hydrogen Water group. His answer to someone asking about the importance of ORP - Oxidation/Reduction Potential is hydrogen water generators is great!

Unfortunately we still see vendors of MLM water ionizers (among others) still selling ORP as an antioxidant, or ORP as proof of the presence of molecular hydrogen in the water. Simply not so.
