Calcium is a vital mineral for bone health because it is the primary component of bone tissue. Approximately 99% of the body's calcium is stored in the bones and teeth, where it provides structural strength and support. Adequate calcium intake is essential throughout life, particularly during childhood, adolescence, and early adulthood when bone growth and development are crucial. Additionally, calcium helps in the maintenance of bone density, and low levels of calcium can lead to conditions such as osteoporosis, where bones become weak and brittle.

Other minerals like iron and zinc play important roles in overall health and bodily functions, but they do not have the same direct impact on bone structure and health as calcium. Sodium, while necessary for various bodily functions, is not associated with bone health in the same way and can actually contribute to calcium loss if consumed in excess. Therefore, calcium is clearly recognized as the critical mineral for maintaining strong and healthy bones.
