Which of the following micronutrients is known to support bone health?

Calcium is widely recognized as a critical micronutrient for bone health due to its essential role in developing and maintaining strong bones and teeth. It serves as a primary building block for bone tissue and is necessary for achieving optimal bone density. Adequate calcium intake throughout life, particularly during childhood and adolescence when bones are developing, is crucial for preventing osteoporosis and other bone-related disorders later in life.

While sodium, iron, and zinc each play specific roles in various bodily functions, they are not primarily associated with bone health. Sodium is mainly known for its role in fluid balance and nerve function, iron is crucial for oxygen transport in the blood, and zinc is important for immune function and protein synthesis. Although zinc does have some involvement in bone metabolism, it does not have the same direct association with bone structure and strength as calcium does.
