So far what I've found about M-clay (to see how much of these claims are, in fact, real benefits of the substance, versus how much of these claims could be quackery) is that back in 2007 animal scientists at Texas A&M University demonstrated definite effectiveness of Calcium Montorillonite Clay as an aflatoxin binder in animal feeds.

Hope we can get something good out of this article.

Feed studies by the Veterinary Medical Diagnostics Laboratory at Texas A&M University have shown that Montmorillonite clays can sequester (bind) aflatoxins contained in grains and oilseeds.

Aflatoxins, you might recall, are what were found in a lot of dog food kibbles, which killed so many dogs a few years back. They are produced in grains, which shouldn't even be a part of the diet of a raw-fed dog.

Still, as suspected, M-Clay does contain a lot of trace minerals--including good ol' germanium

Here is a Wikipedia article on medicinal clays in general: http://en.wikipedia.org/wiki/Medicinal_clay

This is not the same as reading published studies, but it does give a good overview of some of the history, claims, and facts about medicinal clays.
