Minerals are very essential to the proper functioning of a body.
They facilitate enzymatic action, and vitamins can't even perform many of their necessary functions without using minerals as catalysts. However, metallic minerals can be toxic and dangerous to the body. Metallic minerals are hydrophobic, which means they resist interaction with water. A colloid is a particle or substance that retains its identity and remains in suspension. Colloids are very small in size and therefore are easily absorbed by the cells of the body.
