Research very often comes up with different answers. And, frankly, not ingesting Miracle-Mineral-Supplement is not a research tool. As for it being poisonous, so are the ingredients of homeopathic medicine. But like Miracle-Mineral-Supplement , they are ingested in such small amounts, that very often, positive results have been recorded. I think that since you haven't taken Miracle-Mineral-Supplement , you should back off.
There are people that have taken it and gotten good results. Don't invalidate their experiences.
