Vitamin D deficiency

Vitamin D is a fat-soluble vitamin that occurs naturally in some foods, is added to some fortified foods, and is also available as a dietary supplement. It is essential to our health and can promote the formation of healthy bones in children, adults and the elderly. Without enough vitamin D, our bones will become thin, brittle or weak; but if the level of vitamin D is sufficient, it can maintain bone health. Studies have shown that taking vitamin D and calcium together can protect against osteoporosis in the elderly.
