Vitamin D

Mushrooms are the only source of vitamin D in the produce aisle and one of the few non-fortified food sources.

What is Vitamin D? Vitamin D helps build and maintain strong bones by helping the body absorb calcium. Vitamin D is available via diet, supplements and sunlight, which is why it is also referred to as the “sunshine vitamin.”

Vitamin D in Mushrooms

All mushrooms contain some vitamin D1, but mushrooms have the unique ability to increase vitamin D amounts due to UV-light or sunlight exposure2. Similar to humans, mushrooms naturally produce vitamin D following exposure to sunlight or a sunlamp: mushrooms’ plant sterol – ergosterol – converts to vitamin D when exposed to light.
