Store-bought mushrooms contain on average 2.3 mcg of vitamin D per 100 grams (about 3-4 mushrooms), which is 23 percent of your daily needs. This number can be greatly increased when mushrooms get additional sun.

A study by the University of Sydney found that mushrooms left in the midday sun for about one hour produced roughly 10 mcg of vitamin D per 100 gram serving. Another found that a short burst of UV-B rays increased vitamin D2 levels to 17.6 mcg per 100 grams, equal to levels found in other food sources of vitamin D, such as fatty fish.

This is a big dose of the sunshine vitamin. Be sure to check with your doctor before replacing vitamin D supplements with natural alternatives, but mushrooms are a great way to boost your levels naturally. Simply allow your mushrooms to sunbathe outside or on an open windowsill for 1-2 hours to create your own natural vitamin D “supplement”… one that actually tastes good, too.
