The "major health bodies" like FDA and ALL others are controlled by pharma. Unfortunately we leave in a money driven world. Like someone already wrote: in the orthodox medicine doctors are the sell agents for pharma.
Could you imagine what would be the outcome of clinical evidence that Miracle-Mineral-Supplement is effective? The pharma industry would go crazy
I don't know if Miracle-Mineral-Supplement is working, I want to try it, had some bad experience with it(too high dosage), but I also have not read any properly written bad report about it.
And the fact that makes me thinking that Miracle-Mineral-Supplement IS GOOD is that the medical industry has NO INTENTION of publishing some clinical studies. I am very sure they made them already.
