Minerals provide structure to our skeletal system and promote nerve impulses, along with an array of other functions. The minerals calcium, chlorine, magnesium, phosphorus, potassium, sodium and sulfur are required in abundance in the body. While all these are essential, chlorine, sodium and phosphorus are abundantly available in food and water.
Other minerals are also needed in the body but only in trace amounds; boron, chromium, copper, fluroine, germanium, manganese, molybodenum, selenium, silicon, vanadium and zinc. Iodine is needed in the thyroid to regulate metabolism and iron is responsible for carrying oxygen in the red blood cells. While both are vital, they too are only required in trace amounts.
