Most really see either no significant change or no change at all.
The product is probably nothing more than sodium chlorite. I have emailed the company repeatedly but the only response they will give is "Our product is not a compound but oxygen that is loosely bonded with sodium."
"Stabilized oxygen" is said to be the ingredient, and the company describes this more accurately as "oxides of chloride" which is what you get when you bind an oxygen molecule with a chloride. In this case, chlroine dioxide (CLO2) is the "oxygen molecule" and binds it with sodium chloride (Na). This ends up creating the compound NaCLO2 which is nothing more than sodium chlorite - the same compound you purchase from Dr. Katz & other companies that sell "chlorine dioxide" products.
