Everybody—and every body—needs vitamin D. Vitamin D is vital for bone growth and repair and many other bodily functions. A deficiency can cause a number of health issues including weak bones and muscles and, in severe situations, rickets. Unfortunately, especially during adolescence—which also happen to be peak bone building time—vitamin D deficiency is common.
One reason for the prevalence of vitamin D deficiency is because very few foods in nature contain it. Fish liver oils and fish like salmon, tuna and mackerel are the best sources, and small amounts of vitamin D are found in beef liver and egg yolks. Fortified milk, juice and some cereals are other good sources of the vitamin. However, it is important to note (1) that many dairy products made from milk, such as cheese and ice cream are not fortified; and (2) at least one study found that 15% of milk samples from the U.S. and Canada had no vitamin D and more than half had less than 80% of the vitamin D content stated on the label.
