These highly absorbable, water-soluble colloidal minerals are derived from shale deposits in Utah, which were formed when plant life underwent natural decomposition during the prehistoric eras. Plants and fruits likely contained at least 77 minerals which became water-soluble as they transmuted through the root system to become part of a luscious succulent vibrant and life-sustaining source of food. Plant-derived minerals have been encapsulated in the earth as a pure food since that time. Our bodies need a steady stream of minerals - many in trace amounts - to function properly. Our Plant Derived Minerals products are liquid concentrates containing over 70 Plus minerals from prehistoric plants in their unaltered colloidal form.
