Osteomalacia is the adult counterpart of rickets in children. Both of these conditions are caused by a defect in vitamin D availability or metabolism. Osteomalacia is characterised by poor bone formation, resulting in weakened bone. 10 million people, approximately one person in every 17, has osteomalacia (144). The lifetime prevalence of fractures has been found to be 37.5% among men and 21% among women with proportions among white, mixed and black subjects at about 29%, 31% and 22%, respectively
Osteomalacia due to poor intake is reversed by ensuring adequate diet, sunlight exposure and vitamin D and calcium supplements if necessary. In general,vitamins D2 and D3 have been considered as good as each other, although some small new studies have suggested that vitamin D3 is actually more effective. A recent review suggested that there’s no difference between the effectiveness of vitamin D2 or D3 when taken as a tablet. At the moment, the vitamin D provided in multivitamin tablets can be either vitamin D2 or D3, but many companies are now moving towards using vitamin D3.
