A colloid is a particle substance that retains its identity and remains in liquid suspension.
Colloids are very small in size and therefore easily absorbed by the cells of the body.
Plants convert metallic minerals into this form. Dr. Carey Reams, a well known biophysicist and biochemist, discovered that colloids can get so small they can go through glass. They have a natural negative electrical charge. Dr. Reams found that the human body requires 84 of the known 106 elements to maintain optimum health. Many more than is currently recognized.
