    Excellent clay at the greatest price!

    Posted by Joshua Maria on 10th May 2019

    After much study of the use of clay and after paying $10 for a pound in health stores, this is by far the best deal this side of the Atlantic! I soak my feet in a container of warm water with one-fourth cup of clay. They must warn against internal use by law but I take a tablespoon of clay with a teaspoon of baking soda and 2 tablespoons of apple cyder vinegar every day for intestinal and entire body cleanse on the inside! Best internal cleanse without side effects!! I bought the 50-pound bag! 25 stars! Share with family and friends!

    Excellent value

    Posted by TIA on 3rd Apr 2019

    Purchasing bentonite clay from beauty supply stores is so expensive it’s not even worth purchasing for the small amount you get, and they pre-load it with chemicals and oils so that the work is done, not realizing the whole purpose of using bentonite to treat your hair is to remove product buildup and harsh materials. This is the best deal I’ve ever seen on good quality clay.

    Love, love, love

    I have been using essential oils to make personal care items for a while now, and wanted to try to incorporated bentonite clay to make a few more items. I cannot say enough good things about this clay! It is great quality, works wonderfully in shampoo; despite warnings from the site, I used it in homemade tooth powder as well (you spit it, so...). Shipping on their end is great (not my carrier's end, but that's a different story :) ), all of their products are superior quality. I have NEVER had an issue with the quality of their products!! Love ordering from here!
