Calcium is essential for maintaining healthy bones as it plays a critical role in bone structure and strength. It is the primary mineral found in bones, accounting for about 99% of the body's total calcium content. Adequate calcium intake is vital for bone development during childhood and adolescence, as well as for preserving bone density in adulthood. If calcium levels are insufficient, the body may withdraw calcium from the bones to maintain necessary physiological functions, leading to weakened bones and increasing the risk of fractures and osteoporosis.

While other minerals, such as zinc, do contribute to bone health and play roles in various bodily functions, calcium is specifically recognized for its primary function in bone mineralization. Sodium and iron, while important for other physiological processes, do not have the same direct impact on bone strength and health as calcium does. This makes calcium the crucial mineral for maintaining healthy bones.
