The primary mineral that provides strength to bones is calcium. Calcium phosphate, specifically in the form of hydroxyapatite, forms the mineral matrix of bone tissue, giving bones their rigidity and strength. This essential mineral is vital for maintaining bone density and overall skeletal health. Adequate calcium intake is crucial, particularly during periods of growth, such as childhood and adolescence, as well as during aging when bone density may decrease, potentially leading to conditions like osteoporosis.
