# Are the mushrooms darker when exposed to ultraviolet lights?

 

Vitamin D enhanced mushrooms will be slightly darker, but so slight that it takes a laboratory instrument to detect the difference. This is because we only expose them to light for a short interval of time under well-controlled conditions.
