Vitamin D: Although our bodies can make vitamin D after skin is exposed to sunlight, most people now limit sun exposure. Vitamin D is naturally present in very few foods; it is added to many, though, and is also available as a dietary supplement. The most common natural and fortified sources of vitamin D include some fatty fish such as tuna and salmon; most milk; and many types of orange juice, yogurt, cheeses, breakfast cereals, breads and soy drinks. Most milk is fortified with 100 IU of vitamin D in an 8-ounce serving.
Vitamin D: The safest and most economical way to ensure adequate vitamin D status is to use oral dosing of native vitamin D3, cholecalciferol. Both daily and intermittent regimens work well. [Russo: 2011] Serum 25(OH) D can be expected to rise by about 1 ng/mL (2.5 nmol/L) for every 100 IU of additional vitamin D each day. [Heaney: 2008]
