The chemical element essential for healthy bones is calcium. This mineral plays a critical role in forming and maintaining strong bones and teeth. Calcium helps in the growth and development of bone tissue and is important for bone density throughout life. The body requires calcium not only for bone health but also for proper muscle function, nerve signaling, and blood clotting. Adults typically require around 1,000 to 1,200 mg of calcium daily, which can be obtained through dietary sources like dairy products, leafy greens, and fortified foods, as well as supplements if necessary.
