Monterey Mushrooms® Have Vitamin D

Monterey Mushrooms® grows a full line of mushrooms that are high in vitamin D.  By exposing our mushrooms to a proprietary light system that mimics sunlight, we help mushrooms produce precise levels of vitamin D in a natural way.  As a result, one serving (about 3 medium mushrooms) of these specially grown mushrooms provides 10 mcg (400 IU) of vitamin D per serving, which is a whopping 50% of the recommended Daily Value (DV)!


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 much the same way humans do, by using the sun’s rays to produce 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.


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


Mushrooms provide varying levels of vitamin D, as seen on the below graph.  Monterey MushroomsR offer higher levels of vitamin D for our light-exposed white buttons, baby bellas, and port caps.  Ask your local store to carry these healthful options.

Exposing mushrooms to light, such as sunlight, causes a measurable increase in vitamin D2 content.  The mushrooms in our high vitamin D product line have been exposed to light to provide you with 10 mcg (400 IU) per serving.
