Vitamin D is a natural vitamin that is present in very few foods and is needed by the body for calcium absorption. Vitamin D is naturally obtained through sun exposure but increases a persons risk for skin cancer from exposure to harmful UV rays. Without sufficient vitamin D in a persons diet, bones become weak and brittle and a person becomes more susceptible to bone fractures and breaks. Most people have no symptoms of Vitamin D deficiency. Taking Vitamin D supplements regularly also lowers a persons risk for osteoporosis.
