 Definition: This steroid vitamin is needed for calcium metabolism, and is found in egg yolk, fatty fish and enriched milk, but, since it is synthesized in the skin when an individual is exposed to sunlight, it isn't normally needed in the diet. It is used to treat rickets, a nutritional disease that causes poor bone growth in children.
