Few foods contain significant amounts of vitamin D naturally, and the ones that do are not foods you want to overdo: butter, cream, egg yolks, and liver. But there are some good sources. All milk -- including skim milk -- is fortified with vitamin D at a level of 100 IU per cup. Some manufacturers also fortify cereals with vitamin D. Cod liver oil, as a supplement, contains about 1,200 IU of vitamin D per tablespoon. Cod liver oil should be used cautiously as a dietary supplement, however, because it also contains high levels of vitamin A -- that can have toxic effects.

Egg yolks are a source of Vitamin D,
but aren't a food that is healthy to
eat in excess.
You cannot overdose on vitamin D from sun exposure because it limits itself. Of course, you can get too much sun, increasing your risk of skin cancer. Unfortunately, because sunscreens filter out the ultraviolet rays that burn your skin, they block the manufacture of vitamin D as well. Exposing unprotected skin to the sun in the early morning or late afternoon hours solves both problems.
Clouds, smog, clothing, and even window glass also filter out ultraviolet rays. Housebound people, those with dark skin, those that cover most of their skin when outdoors and those who live in cloudy, northern climates are most likely to be deficient in vitamin D. These people must get vitamin D from foods.
Here is a chart you can use to find foods rich in vitamin D:
| Sources of Vitamin D ||Food Quantity || Vitamin D (mcg)|
| Tuna salad || 1 cup ||7.5|
| Skim milk || 1 cup ||2.5|
|Milk|| 1 cup ||2.5|
| Egg substitute || 1/2 cup ||2.1|
|Eggnog|| 1/2 cup ||1.5|
| Raisin Bran || 1 cup ||1.4|
| Total cereal || 1 cup ||1.2|
| Product 19 || 1 cup ||1.2|
