Everything You Need To Know About Zeolite For Detox

Zeolite has a strong negative charge and thus is attracted to positively charged molecules. 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. This makes zeolite an effective detox method for a number of toxic elements.
