Monterey Mushrooms® Have Vitamin D

Monterey Mushrooms® grows a full line of mushrooms that are 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 precise levels of vitamin D in a natural way.  As a result, mushrooms can easily provide 100 percent 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.


Vitamin D helps our bodies absorb calcium which is important for building and maintaining good bone health during adolescence and throughout life. Adequate calcium and vitamin D, as part of a well-balanced diet, may reduce the risk of osteoporosis and related bone fractures.


Exposing mushrooms to light, such as sunlight, whether by design or unintentionally causes measurable increases in vitamin D2 content. The mushrooms in our high vitamin D product line have been exposed to light to provide you with 100 percent of the recommended daily value per serving.

If you are exposed to insufficient sunlight, you may be deficient in vitamin D. Mushrooms may help you incorporate vitamin D rich food into your diet.

Monterey Mushrooms 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 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 after cooking or freezing.
