Answer:
Your body is getting rid of the excess riboflavin (B2), by excreting it in the urine.
That's why it's a waste to take too many vitamins, especially something like Vitamin C. All it does is give you expensive pee when your body gets rid of it!
This is from vitamin B2 or riboflavin. It is water soluble so whatever your body doesn't need, it flushes out in your urine.
I've heard that it's from taking the increased vitamin C.
