Calcium is the mineral essential for healthy bones. It plays a critical role in bone formation and maintenance, helping to build strong and dense bones throughout a person's life. A significant portion of the body's calcium is stored in the bones and teeth, contributing to their structure and strength. In addition to bone health, calcium is vital for various bodily functions, including muscle contraction, nerve signaling, and blood clotting. To ensure adequate calcium intake, individuals can consume dairy products, leafy greens, and fortified foods. Maintaining optimal calcium levels is essential for overall health and well-being.
