Millions of years ago, volcanoes exploded and spread ash into rivers and lakes. Over a very long time, that ash slowly changed into a special kind of clay called bentonite clay. Even though it looks like ordinary dirt, scientists discovered that this clay has a very unusual property hidden inside it.
Each tiny piece of this clay carries a natural negative electrical charge — think of it like a miniature magnet. Many harmful substances inside the body, such as certain heavy metals and toxins, carry a positive charge. Opposites attract, just like magnets.
The clay is made of extremely thin layers stacked together like pages in a book. A single spoon of clay contains an enormous surface area because those layers spread out at a microscopic level. Scientists say one gram of bentonite clay can have a surface area larger than a basketball court.
When the clay travels through the digestive system, it does not melt or dissolve. It stays solid while moving through the stomach and intestines. Along the way, its negatively charged surface can attract and hold positively charged substances. Some researchers believe this may help bind certain materials before they are absorbed into the body. The clay then leaves the body naturally through waste.
Note: research on bentonite clay is still ongoing. Like any supplement, it should be used carefully and with proper guidance, as it may also bind to beneficial minerals if overused. Always consult a healthcare professional before using it regularly.
