Zeolite is an alkaline mineral that is very porous and is one of the very few minerals that is negatively charged by nature. Since most toxins, such as heavy metals, radiation, and pesticides, are positively charged, zeolite is pulled to the toxins, like a magnet, and sucks them up into its structure.These dangerous substances become trapped in zeolite's cage structure, and …
