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.
Vitamin D belongs to a class of nutrients called fat-soluble vitamins. As the name implies, you need dietary fat to help break down these vitamins and absorb them into your body.
