Vitamin D, often called the “sunshine vitamin”, is really a hormone that has been categorized as a vitamin. Only a few foods naturally contain vitamin D, including fatty fish and cod liver oil. Fortified foods such as milk and cereal are the major dietary sources of vitamin D, but is estimated that 40% of the U.S. population is vitamin D deficient. Therefore, supplementing the diet with extra vitamin D is essential for optimal health.
