Thank you for joining and thank you for posting an interesting, and potentially beneficial topic. Unfortunately, I have not researched this substance enough to provide valuable feedback at this time.
The trouble with substances like these is they inspire quackery. I don't know if M-Clay can do all of the things you have listed, but (of these things) I would say the third element of your list is the most probable--meaning I am sure it provide a fine array of trace micro-nutrients). However, whether this substance does all that its proponents claim ("balance the body," "remove parasites," etc.) is something else again. I have heard many of the same kinds of claim for many other substances, which ultimately were debunked, the last one being for Diatomaceous Earth. I spent about a week researching this substance, and I looked up multiple legitimate studies funded by Government and Universities alike, and at the end of the day, all DE did was provide silica, some other trace elements, but it sure was not a legitimate wormer or "cure-all" like its proponents claimed.
Well, here again, it would be at least a several hour (or several day) task to really research actual published studies of M-Clay in the effort to separate fact from fiction. Apple Cider Vinegar is another "wonder substance" that has webpage-after-webpage devoted to it, yet very little actual scientific evidence to support its use.
Maybe over the coming week I will put in the time to read some actual published studies of M-Clay, and will provide the links, so that we can see how much of these claims are, in fact, real benefits of the substance, versus how much of these claims prove to be quackery.
Cheers,
Jack
