Vitamin D is a fat-soluble vitamin that is naturally present in very few foods, added to others, and available as a dietary supplement. It is also produced endogenously when ultraviolet rays from sunlight strike the skin and trigger vitamin D synthesis.ood. Very few foods in nature contain vitamin D. The flesh of fatty fish (such as salmon, tuna, and mackerel) and fish liver oils are among the best sources [ 1, 11 ]. Small amounts of vitamin D are found in beef liver, cheese, and egg yolks.
Surprisingly few foods contain vitamin D -- unless it's added to the food. That's because your body is built to get vitamin D through your skin (from sunlight) rather than through your mouth (by food). But once your body has enough, it doesn't matter whether you got it through your skin or through your stomach.ther food sources of vitamin D include: 1  Cod liver oil (warning: cod liver oil is rich in vitamin A; too much may be bad for you). 2  Tuna canned in water. 3  Sardines canned in oil.
