They are usually found at extraordinarily small levels in our bodies. In fact, they occur in the “parts per million” range. In spite of the relatively low concentrations of these minerals, scientists have discovered that they play a vital role in our health. Trace minerals are important in the proper functioning of enzyme systems, nerve conduction and muscle function, assisting with transfer of nourishment into cells, providing the framework for tissues, and regulation of organ functions. These functions are not possible without a constant, adequate supply of these vital minerals.
