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.
This has caused a âboomâ in vitamin D research; scientists are investigating its role in everything from heart disease and diabetes to depression, cancer and the common cold. You get Vitamin D in two ways: by consuming it in foods or supplements, and by making it in your skin when sunlight hits it. Vitamin D doesnât occur naturally in a lot of foods â unless youâre a really big fan of cod liver oil or mackerel, you wouldnât get nearly enough â so many foods are fortified with it.
