A single serving of salmon provides more than the recommended Daily Value of the nutrient, according to the World's Healthiest Foods. A single serving of sardines contains more than 40 percent of the Daily Value, and tuna fish provides a little less than 25 percent of the recommended daily intake.

Vitamin D in any form is not naturally present in many foods, but certain grocery goods are fortified with vitamin D, according to the NIH Office of Dietary Supplements.

Infant formula is fortified with vitamin D under federal government mandate. Fortified foods are the source of most Americans' dietary vitamin D.
