A major element found in our bones is calcium. Calcium phosphate is the main mineral component of bone, providing it with strength and structure. The human body contains about 1 kilogram of calcium, mostly stored in bones and teeth in the form of calcium phosphate compounds like hydroxyapatite
. In addition to calcium, phosphorus is another major element in bones, present mainly as phosphate. Together, calcium and phosphate form the mineral matrix that gives bones their hardness and rigidity
. Other important minerals in bones include magnesium and trace elements, but calcium and phosphorus are the primary major elements.
