I don't know...but a friend who is back on..due to extreme sides from the mms, went off...that she constantly smelled chlorine..like a swimming pool or heavily chlorinated tap water...and she was titrating up as directed but never made it to the suggested number of drops. She was at 6 drops them dropped to 5 but continued to have bad sides and the chlorine smell.
i think that the claims about Miracle-Mineral-Supplement and Humble's words are in dire need of questioning and research.

Thats right Its the chlorine that is the chemical and its a gas,which is needed.
He says the only by-products are salt and hypochlorous acid (which is used by the immune system.)

The chemical that you smell is chlorine dioxide and it smells like chlorine but does not have the same toxic breakdown products of chlorine. It breaks down to chlorite, chlorate and ultimately chloride(salt) not chlorine. Chlorite and chlorate are somewhat toxic in certain amounts but do not persist. Some hypochlorous acid may also be produced in the body
