Bentonite Clay (not your everyday dirt) is supposed to be good for you. I have some and have tried it on occasion without any ill results.
Kaopectate used to contain kaolin, which is a clay. Both the kaolin and the pectin have been removed from the product. Supposedly, both ingredients were removed because they were ineffective.
So, I have some doubts about bentonite taken internally, although I have seen the ads, which I find hyperbolic. I believe it is the basis for facial masks to remove blackheads. I know it can be purchased bulk for that purpose from cosmetic ingredient suppliers.
You state you had no ill results. What benefits did you experience?
