Roll Call does not check drug interactions or assess personal safety.

The common white or brown culinary mushroom, dried or powdered for use as a food ingredient or supplement.

Why it’s used

Included for its nutrient content — including some fiber, B vitamins, and, when exposed to UV light during growing, vitamin D — or simply as a whole-food ingredient.

What the evidence says

Button mushroom is a well-established food, but as a standalone supplement ingredient it has little dedicated clinical research behind specific health claims. Any vitamin D content depends heavily on UV exposure during cultivation and is not standardized across products.

Context
