Is sunlight a source of vitamin d?

Yes & foods. 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.
Yes and no. Sunlight is a component of the reaction that turns cholesterol into vitamin d3. Cholesterol gets a bad RAP in mainstream media, but it is the precursor to most hormones. Vitamin d is really more of a hormone than a vitamin. A typical person makes about 15000 units of d3 with 30 minutes of sun exposure.
No. Vitamin D or its elements are in the diet. Sun light is important because it is responsible for the first step in its pathway of activation on the body.
The most important. You would have to eat pounds of fish liver every day in order to get enough vitamin d just from your diet. The only logical conclusion is that our main source of vitamin d must be uvb rays of the sun. Uvb does much more than just help produce vitamin d from the cholesterol within the cell membranes of your skin cells. Uvb has profound effects on pineal function. Sunlight is a vital nutrient!
