The essential mineral for maintaining healthy bones is calcium. Calcium is crucial for bone formation and maintenance, as it provides strength and structure. In addition to its role in skeletal health, calcium also supports other vital functions such as muscle contraction, nerve signaling, and blood coagulation. Adequate calcium intake can be achieved through dietary sources like dairy products, leafy greens, and fortified foods. Understanding calcium’s importance helps in preventing conditions like osteoporosis and promoting overall bone health throughout life.
