Which supplement combination is most appropriate to prevent decreased bone mineralization?

• A. Calcium & Niacin
• B. Calcium & Vitamin D
• C. Niacin & Vitamin C
• D. Vitamin C & Vitamin E

Answer: (B)

Bone mineralization hinges on having enough calcium available and ensuring it can be absorbed and deposited properly. Calcium provides the mineral content for bone, while vitamin D increases the gut’s absorption of calcium and supports the mineralization process in bone tissue. If vitamin D is low, calcium taken in may not be absorbed efficiently, weakening bone mineralization even with adequate calcium intake. The other pairings don’t address this crucial calcium–vitamin D interaction; they lack vitamin D’s role in calcium absorption (and thus in bone mineralization), so they’re not as effective for preventing decreased mineralization. Therefore, combining calcium with vitamin D best supports bone mineralization.
