Mushrooms and animal skins create vitamin D when exposed to sunlight. Mushrooms are rich in the vitamin D precursor ergosterol, which ultraviolet B (between wavelengths of 290 nm to 315 nm) converts to ergocalciferols, also called provitamin D2.
Can you put mushrooms in the sun for vitamin D?
When commonly consumed mushroom species are exposed to a source of ultraviolet (UV) radiation, such as sunlight or a UV lamp, they can generate nutritionally relevant amounts of vitamin D.
How can you enhance the vitamin D content of mushrooms?
Holick and other researchers have found that we can increase levels of vitamin D even more by exposing mushrooms to prolonged ultraviolet light. Similar to when humans are exposed to sunlight (or a sunlamp), mushrooms convert a precursor to vitamin D, called ergosterol, into vitamin D₂ when exposed to UV light.
Does cooking destroy vitamin D in mushrooms?
Six raw mushrooms have . 2 milligrams of vitamin D, a nutrient that benefits your bones by helping your body absorb calcium. Cooking them depletes their vitamin D content by half.
How can I raise my vitamin D level quickly?

Which mushroom is highest in vitamin D?
The most vitamin D was found in shiitake dried with gills up that were exposed to sunlight for two days, six hours per day. The vitamin D levels in these mushrooms soared from 100 IU/100 grams to nearly 46,000 IU/100 grams (see chart). Their stems, though, produced very little vitamin D, only about 900 IU.
