The Opotowski team, which found that low vitamin A levels had as great an effect lowering BMD as did high vitamin A levels, suggested that vitamin A deficiency may contribute to increased fracture risk by allowing bone matrix to grow faster than it can be mineralized.12 Indeed, although the net effect of vitamin A is to stimulate osteoclasts and slow the growth of osteoblasts, vitamin A also causes osteoblasts to secrete a variety of enzymes and other proteins that are important to bone mineralization, including osteocalcin, which is a protein that plays a direct role in attracting and binding calcium within the bone matrix.6 By slowing the growth of the matrix but increasing the rate at which it is mineralized, adequate vitamin A helps to ensure sufficient bone density.
