Even an amino acid chelated tablet is liquefied and micrionized with hydrochloric acids and enzymes before it is reduced to the molecular form. Try dissolving an amino acid chelated mineral tablet or powder in water if you doubt this. In short, colloids on the smaller end of the spectrum behave like solutions while colloids on the larger end of the spectrum behave like a suspension. Colloidal mineral products contain trace amounts of aluminum, lead, and arsenic with aluminum usually being the most abundant. Aluminum is the third most abundant element in the earth's crust.
All plant life contains some aluminum in a hydrophilic chelated colloidal form.
Naturally occurring aluminum silicate found in humic matter is nontoxic and essential for the development of normal healthy plants. Only metallic aluminum such as that found in deodorants and cooking pans may have adverse effects but this is still more theory than fact. Several theories now exist about the biological use of minerals in the body, none of which are conclusive or absolute. It is known, however, that certain forms of minerals are absorbed more efficiently through the intestinal wall than are others, but no conclusive evidence exists showing these minerals to be more efficient once they enter the blood stream. Colloidal minerals also contain trace amounts of lead that appears in 15 ppm of the earth's crust.
