A colloid is a particle substance that retains its identity and remains in suspension.
Colloids are very small in size, and therefore easily absorbed by the cells of the body.
Plants convert metallic minerals from the soil into this form. Colloidal biochemistry is a very neglected branch of science, and much research has yet to be done into the exact function of all the various elements. Colloidal minerals , as found in plants, are not toxic. In fact, colloidal minerals are very beneficial. As a result, health care professionals and the media have recently voiced concerns for public safety and health risk.
