What role does calcium play in the body?

Calcium plays a crucial role in the body, particularly in the formation and maintenance of strong bones and teeth. It is a vital mineral that comprises a significant portion of the structure of bones, providing them with strength and rigidity. Approximately 99% of the body's calcium is stored in the bones and teeth, where it supports their structure and function. Adequate calcium intake is essential throughout life, especially during key growth periods such as childhood and adolescence, as well as later in life to help prevent bone loss and conditions like osteoporosis.

While calcium does have various functions in the body, including roles in muscle contraction, nerve transmission, and blood clotting, its primary and most well-known function is its contribution to skeletal health. Therefore, stating that calcium is essential for strong bones and teeth is accurate and reflects its critical importance in maintaining the body’s structural integrity.
