Calcium is one of the major minerals. It is the most abundant mineral in the human body. Accordingly, sufficient quantities of calcium must be consumed daily. Ninety-nine per cent of the calcium in our bodies is deposited in the bones and teeth. However, in order to effectively absorb the calcium we consume, an adequate amount of vitamin D must be present.

The mineral calcium contributes to
