Intimate association with calcium in the bone formation process. Vitamin A is necessary for the proliferation of cartilage and bone growth. Without Vitamin A, bone rebuilding is impaired and bones develop in abnormal places. Vitamin C is essential for the formation of collagen, the organic component of bone. Without Vitamin C, the collagen matrix of bone.
Vitamin D performs several complex functions that affect the metabolism of calcium.
