Which vitamin is associated with the maintenance of bone density?

Bone density is the amount of bone mineral present in bone tissue. The higher the bone mineral content, the denser the bones are. Several vitamins are important to bone health. Vitamin $\mathrm{B}_{12}$ has an effect on bone building cells. The low levels of $\mathrm{B}_{12}$ result in the higher risk of osteoporosis in both men and women and thus results in lower bone density. Vitamin $\mathrm{C}$ is essential for the formation of collagen, the foundation that bone mineralization is built on. Increased levels of vitamin $\mathrm{C}$ results in greater bone density. Vitamin D is most essential for greater bone density. It helps the body to absorb calcium.
