Which mineral is essential for bone health?

Calcium is an essential mineral for bone health because it plays a critical role in the development, maintenance, and strength of bones. It is the primary mineral found in bones, making up about 99% of the body's calcium store. Adequate calcium intake is necessary to reach peak bone mass, particularly during childhood, adolescence, and early adulthood when bone growth and development are at their highest. Additionally, calcium helps prevent bone loss later in life, which can reduce the risk of osteoporosis and fractures.

While other minerals such as zinc may support various physiological functions and contribute to cellular metabolism and immune function, they do not have the same direct impact on bone structure and density as calcium does. Iron, on the other hand, is crucial for transporting oxygen in the blood, and sodium is primarily involved in fluid balance and nerve transmission but does not significantly contribute to bone health. Thus, calcium's fundamental role in forming and maintaining the skeletal system makes it the mineral essential for bone health.
