Minerals are essential substances that the body needs in minute amounts on a regular basis for normal functioning. Minerals are absorbed from the diet and are used to produce enzymes and hormones, to regulate glucose as well as in the formation of blood cells, bone, teeth, muscles and connective tissue.
