Zeolite
Finely ground these vulcanic minerals (89 bis 95 % Klinoptilolite), because of their honeycomb-like crystalline structure, act as ion-exchanger. Their crystalline grid of 0,4 nanometer is exactly the right size to attract heavy metals and ammonium compounds. Since this happens already in the intestines, the entero-hepatic circulation of those toxins gets interrupted. Liver & kidneys are relieved and the immune-system can redirect saved energy to other tasks. Though only approved as building material and for agricultural use, zeolite leaves you without know side-effect, even if taken in large quantities, since any excess gets simply eliminated.
Within the scheme of guided symbiosis the very same crystalline structure of zeolite provides an "operational base" for the Effective Microorganism. They get less quickly expelled from the intestines because they can take shelter in it like a hermit crab.

Natural zeolites form where volcanic rocks and ash layers react with alkaline groundwater. (..) zeolites are the aluminosilicate members of the family of microporous solids known as "molecular sieves". The term molecular sieve refers to a particular property of these materials, that is the ability to selectively sort molecules based primarily on a size exclusion process. This is due to a very regular pore structure of molecular dimensions. (..) zeolites are used in the treatment of Lyme disease, as a detoxifier.
