Question:
Why does urine turn bright yellow from taking vitamins?
Answers:
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!
