Zeolite Dosing: Finding the Right Amount

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.

Zeolite - Wikipedia

Zeolites are microporous, aluminosilicate minerals commonly used as commercial adsorbents and catalysts. The term zeolite was originally coined in 1756 by Swedish mineralogist Axel Fredrik Cronstedt, who observed that rapidly heating the material, believed to have been stilbite, produced large amounts of steam from water that had been adsorbed by the material.
