vitamin D is a nutrient that is essential for healthy bones and teeth. There are two forms of

vitamin D that are important for nutrition: vitamin D2 and vitamin D3. Vitamin D2 mainly

comes from fortified foods like breakfast cereals, milk, and other dairy items. Vitamin D3 is

made by your own body when you are exposed to sunlight. It is also found in some foods,

including eggs and fatty fish, such as salmon, tuna, and mackerel.
