What leafy vegetables contain vitamin d?

Not many. Vegetables, as a rule, are a lousy vitamin d source. The best vitamin d comes from your skin when it's exposed to sunlight. The best source of dietary vitamin d is cold water fish. Further, whether vegetable derived vitamin d (d2) does the same thing as that which comes from animal sources (d3) is still a matter of dispute. Many vitamin d experts think that it does not.
Rare, try these. The flesh of fatty fish (such as salmon, tuna, and mackerel) and fish liver oils are among the best sources. Small amounts of vitamin d are found in beef liver, cheese, and egg yolks. Some mushrooms provide vitamin d2 in variable amounts. Ready-to-eat breakfast cereals often contain added vitamin d, as do some brands of orange juice, yogurt, margarine and other food products.
