The mineral vital for bone health is calcium. It plays an essential role in maintaining bone density and strength. Adequate calcium intake is crucial during childhood, adolescence, and early adulthood to build a strong skeletal system. Additionally, vitamin D is essential for calcium absorption. Insufficient calcium can lead to issues like osteoporosis in later life, increasing the risk of fractures. A balanced diet rich in dairy products, leafy greens, and fortified foods can help ensure optimal calcium levels.
