Bentonite clay is compromised mostly of negative ions. Toxins and heavy metals in the body are made of positive ions. Bentonite clay works like a magnet that bonds to toxins and helps to eliminate it out of the body.
There are two main types of Bentonite clay:
1. Sodium Bentonite, when activated by water, can swell up to six times its size and has a electromagnetic properties. This makes it very absorbent and helpful for drawing out toxins.
2. Calcium Bentonite particles are smaller compared to Sodium Bentonite, which makes it more effective for remineralizing than drawing toxins out of the skin. These small particles can pass through the colon wall into the bloodstream where it gets rid of toxins and leaves minerals behind.
It is possible for Bentonite clay to have a mix of both sodium and calcium.
