What is a Mineral?
Minerals are actually the basic constituents of all matter. They are part of living tissue as well as existing in their inorganic form in the earth. Approximately four or five per cent of our body is made up of mineral, mainly within the skeleton, with calcium and phosphorous being the most abundant. Additionally the body is made up of trace minerals, for example iron and zinc, still essential for life and health, but present in very small amounts.
