The mineral essential for strong bones and teeth is calcium. As a vital nutrient, calcium plays a crucial role in developing and maintaining the structure and health of bones and teeth throughout a person’s life. In children and adolescents, adequate calcium intake is particularly important for bone growth and density. Adults and the elderly also need sufficient calcium to prevent bone loss and conditions like osteoporosis. Dairy products, leafy greens, nuts, and fortified foods are rich in calcium. If dietary intake is insufficient, supplements may be recommended; however, it's essential to consult a healthcare professional before starting any supplementation.
