A member asked:

I started taking vitamins and now my pee is neon yellow is that normal?

A doctor has provided 1 answer

Yes: You are taking a pricey vitamin to which a very large amount of riboflavin (b2, which is naturally yellow) has been added to change the color of your urine and make it fluorescent. It is intended to make you believe that the vitamins are more powerful. It's harmless.
