Slight trace of aluminum is found in bentonite clay, but no side effects of aluminum in bentonite have been yet noticed. So, it's hardly worth fretting about. Although, researches show that bentonite clay does not cause any side effects; more studies may find out some. Being clay, it might get stuck in the intestines, causing digestion problems.
Bentonite is a name given to a particular clay that was originally found in Fort Benton, Eastern Wyoming. The name was given by W.C. Knight in 1898. Previously, it was called Taylorite, which was named after William Taylor, who first began to draw attention to the clay deposits. Geologists often describe bentonite as a clay mineral containing ...
