As you get older you tend to lose calcium from the bones and it becomes necessary to try and prevent this by ensuring that there is enough calcium in the diet and that this calcium is usable by the body. Vitamin D is made in the body by the action of UV sunlight on the fat layers just under the skin. If there is not enough exposure to sunlight the body becomes short of vitamin D and bode deformities can occur in growing children (rickets).

How is osteomalacia treated?
Oral supplements of vitamin D, calcium and phosphorus may be given depending on the underlying cause of the disorder. Larger doses of vitamin D and calcium may be needed for people with intestinal malabsorption. Monitoring of blood levels of phosphorus and calcium may be indicated for people with certain underlying conditions. Regular daily supplements of vitamin D and calcium are usually used for people with simple vitamin D deficiency, but some people have a single injection vitamin D, in the form of calciferol (vitamin D2). This is stored in the body and can last up to a year before another injection may be needed. People with vitamin D deficiency due to intestinal problems are best treated with calciferol. Most people with osteomalacia find their pain is reduced about two weeks after the injection. Extra calcium may also be needed while bone is healing. Direct exposure of the skin (i.e., hands, face, arms, etc.) to sunlight stimulates the body to manufacture vitamin D. However, both clothing and use of a sunscreen prevent the ultraviolet light that triggers the formation of vitamin D from reaching the skin. Depending on latitude, sunlight during the winter may not provide enough ultraviolet light to promote adequate vitamin D production. At other times during the year, even 30 minutes of exposure per day will usually lead to large increases in the amount of vitamin D made. If it is difficult to get sunlight exposure, full-spectrum lighting can be used to stimulate vitamin D production.

What causes vitamin D production?
The Sun gives off light. The body uses light to convert 7-dehydrocholesterol into pre-vitamin D3. Pre-vitamin D3 forms in to cholecalciferol, vitamin D3.
