Dr. Pivonka, In today’s newsletter it was reported that mushrooms contain Vitamin D. I would like to know how much. Thanks.
Mushrooms generally contain about 4% of the daily value of vitamin D, though some varieties may have more. If they are exposed to certain types of light after harvest however, the amount can increase to 100% (they grow in the dark). Look for specially marked packages of the “D-enhanced” mushrooms for the higher amounts of vitamin D.
