Minerals are inorganic substances in body tissues and fluids that trigger or prevent the production of enzymes and hormones, govern certain of their activities, and serve as raw material for structures such as the bones. Minerals provide the building blocks of our body. There are five in particular that create the base which the body constructs itself around: oxygen, carbon, hydrogen, calcium and nitrogen. However, there are about 20 more essential and trace minerals crucial for mental and physical well-being.The "macrominerals," needed in larger amounts, are calcium, chlorine, magnesium, phosphorus, potassium, sodium, and sulfur. "Microminerals," needed in trace amounts, include chromium, copper, fluorine, iodine, iron, manganese, molybdenum, nickel, selenium, silicon, tin, vanadium, and zinc. Many people have mineral deficiencies and it is important to compensate for this lack of nutrients. Minerals aid in many body functions such as digestion, the immune system, the cardiovascular system, the bones and teeth, the nerve system, and much more. Minerals are a crucial part of maximizing our health.
