Which mineral is crucial for bone health?

Calcium is crucial for bone health because it is the primary mineral found in bones and teeth, providing them with strength and structure. About 99% of the body's calcium is stored in the bones, and it plays a fundamental role in bone formation and maintenance. Adequate calcium intake is essential throughout life, especially during periods of rapid growth, such as childhood and adolescence, and in older adults to prevent bone density loss.

The body continuously remodels bone by breaking down old bone tissue and forming new bone. This process requires calcium, making it vital for maintaining bone density and strength. Furthermore, calcium works in conjunction with other nutrients, such as vitamin D, which aids in calcium absorption from the diet.

While other minerals like iron, sodium, and potassium have important roles in the body—such as oxygen transport, fluid balance, and nerve function—they do not directly contribute to bone structure or density in the way that calcium does. Therefore, calcium is recognized as the key mineral needed to support and maintain healthy bones.
