The mineral essential for promoting healthy bones and teeth is calcium. It plays a pivotal role in developing and maintaining bone strength throughout life, acting as a primary building block in the bone matrix. Adequate calcium intake is crucial during childhood and adolescence for proper bone growth and density. Insufficient calcium can lead to conditions such as osteoporosis, increasing the risk of fractures later in life. Additionally, calcium supports other bodily functions, including muscle contractions and nerve signaling, emphasizing its overall importance for health and well-being.
