Every living cell on this planet depends on minerals for proper function and structure. Minerals are needed for the proper composition of body fluids, the formation of blood and bone, the maintenance  of healthy nerve function, and the regulation of muscle tone, including that of the cardiovascular system. Like vitamins, minerals function as co-enzymes, enabling the body to perform its functions, including all energy production, growth, and healing. Because all enzyme activities involve minerals, they are essential for the proper utilization of vitamins and other nutrients.

The human body must maintain it's proper chemical balance. This balance depends on the levels of different minerals in the body and especially the ratios of certain mineral levels to one another. The level of each mineral in the body has an effect on every other, so if one is out of balance, all mineral levels are affected. If not corrected, this can start a chain reaction of imbalances that leads to illness.

Nutritionally, minerals belong to two groups - macro minerals and the trace (micro) minerals. The macro minerals include calcium, magnesium, sodium, potassium and phosphorus. These are needed in larger amounts than trace minerals. Although only minute quantities of trace minerals are needed, they are nevertheless important for good health. Trace minerals include boron, chromium, copper, germanium, iodine, iron, manganese, molybdenum, selenium, silicon, sulphur, vanadium and zinc.
