Which mineral is essential for strong bones and teeth?

• A. Calcium
• B. Iron
• C. Sodium
• D. Potassium

Answer: (A)

Calcium is the mineral needed for strong bones and teeth. It forms the hard mineral part of bone, the matrix that gives bones their rigidity, by combining with phosphate to create calcium phosphate crystals. Osteoblasts lay this material down during bone formation, and calcium is stored in bone as a reserve to maintain blood calcium levels for nerves and muscles. That's why calcium is the most important for bone strength—adequate intake helps build dense, sturdy bones and teeth, and insufficient calcium can lead to weaker bones over time, with risks like osteoporosis in adults or poor bone growth in children. Iron is mainly involved in transporting oxygen in blood; sodium and potassium regulate fluid balance and nerve impulses, not the bone-strengthening mineral.
