Magnetic Clay™ Baths are a very fine, mineral-rich, clay called [Sodium] Bentonite in its pure form without harmful, commercial emulsifiers. There are over 200 different kinds of Bentonite clay and many of them have a variety of uses and results. Most of them have 15% to 75% aluminum in it. Magnetic Clay Baths have tremendous pulling power due to its high negative (good) charge. We have tested and researched many different clays from around the world and found none that compare with our clay for removal of chemical and metal toxicity.
