What in Monster turns your c**p green?

Question

So yeah, after the 6th time of drinking a monster black ice slurpee from 7/11 I'm p**p turned green for like the 3rd time. And i know it was the monster because my brother and a friend had the same thing going on after we had some monster slurpee. So I just wanna know, What in the drink causes it to turn Green???

Answer 1

Blue food coloring (which is a component of purple dye) passes through your digestive tract unchanged and mixes with a yellow pigment that actually accounts for most of the "usual" brown color. The result is green.
