فيتامين دي
Vitamin D can be synthesized in the skin under the exposure of UVB from sunlight. Oily fish such as salmon, herring, and mackerel are also sources of vitamin D, as are mushrooms. Milk is often fortified with vitamin D and sometimes bread, juices, and other dairy products are fortified with vitamin D as well. Many multivitamins now contain vitamin D in different amounts.
