what foods are good sources of vitamin d
Fatty fish and codfish liver oils are good dietary sources of vitamin D3, according to the National Institutes of Health Office of Dietary Supplements. Beef liver, cheese and egg yolks contain small quantities of vitamin D3. Variable amounts of vitamin D2 are found in some mushrooms exposed to ultraviolet light.
Fortified foods contain vitamin D in the form of either D2 or, more commonly, D3, which is the type produced by human skin exposed to sunlight. Salmon, tuna, swordfish and mackerel are examples of fish whose flesh contains vitamin D, notes the NIH Office of Dietary Supplements.
