Which minerals are listed as important for the development and maintenance of bones?

• A. Sodium, potassium, chloride, magnesium
• B. Calcium, copper, iron, phosphorous
• C. Zinc, manganese, selenium, iodine
• D. Fluoride, phosphate, chromium, magnesium

Answer: (B)

Bone health hinges on minerals that build the mineral matrix and support bone cells. Calcium and phosphorus are the primary minerals that form the hydroxyapatite crystals giving bone its hardness and strength. Copper supports the structural integrity of bone by enabling collagen cross-linking in the bone matrix, which helps the organic framework stay strong. Iron, in turn, supports collagen synthesis and the activity of bone-forming cells, contributing to healthy bone formation and remodeling. Together, these four minerals cover both the mineral content of bone and the key processes that maintain a robust bone structure, making this combination the best fit.
