Calcium is the mineral crucial for bone strength. It plays a significant role in maintaining bone density and structure throughout life. Adequate calcium intake during childhood and adolescence is particularly vital for developing strong bones, which helps prevent osteoporosis later in life. Foods rich in calcium include dairy products, leafy greens, and fortified items. The body also requires vitamin D to absorb calcium effectively. Ensuring sufficient calcium consumption supports not just bone health but also plays a role in muscle function and nerve transmission.
