I read some positive things about clay helping autistic kids. I've also read a couple of studies that said clay was effective at adsorbing mercury. The studies outlined what types of clay were best for adsorbing mercurt, they were kaolanite and bentonite as far as I remember. I read that clay was being considered as a mercury clean up tool.

Most importantly when I muscle test for my bentonite clay it tests better than any other supplement I have. I also took my clay to my naturopath and his vega testing had the same result. I have found muscle testing to be accurate and a indispensible diagnostic tool for myself and when I visit a holistic doctor.
