Vitamin D in Mushrooms

Monterey Mushrooms, Inc. worked with the United States Department of Agriculture to replicate what happens in nature when mushrooms are exposed to light. Through their research efforts, they have found that mushrooms respond to light in much the same way humans do, by converting the sun’s rays into Vitamin D. Mushrooms have a natural level of vitamin D, and when exposed to sunlight they synthesize vitamin D. This increased Vitamin D does not involve any additives, supplements or chemicals. The Vitamin D is stable — maintaining its nutritional value even after cooking or freezing.


No matter how you serve them, either cooked or raw, all of the vitamin D comes through for you.


Mushrooms are the only non-animal source for vitamin D that is available for vegetarians and others. Along with the other benefits of fresh mushrooms to include fiber and antioxidants, we are obviously excited about the opportunity to play an even bigger role in helping people achieve a healthy diet.


Only Monterey offers a full line of mushrooms high in vitamin D. By exposing our mushrooms to UV-B light for a very short period of time, we assist the mushroom into producing very precise levels of vitamin D in a completely natural way.   As a result, mushrooms can easily provide 100% of the recommended value of vitamin D.  Mushrooms are the only source of vitamin D in the produce aisle and one of very few non-fortified food sources.
