I am sorry to correct the Minister but vitamin D does not affect osteoporosis. It is helpful for osteomalacia, the softening of the bones due to vitamin D deficiency, but not very useful for osteoporosis. Exercise is valuable, and at any age it is the only thing that prevents osteoporosis. There are treatments available for osteoporosis but they are not very nice—they involve injections—and are quite expensive. Exercise is the thing.
