The mineral crucial for bone health is calcium. Calcium is essential for maintaining strong and healthy bones, as it constitutes a significant part of bone structure. Additionally, it plays a vital role in various physiological processes, including muscle function, nerve transmission, and blood clotting. Adequate calcium intake through diet or supplements is crucial, particularly during childhood, adolescence, and postmenopausal years, to prevent conditions such as osteoporosis, which results in weakened bones.
