Urine Yellow After Taking Vitamins

Dear Dr. Dave and Dr. Dee,

I noticed that my urine is really bright yellow after taking multi-vitamins. Is this normal?

Dear Pee Problem,

Urine turns bright yellow after taking vitamins because the body has absorbed the B2 vitamin (riboflavin). The body absorbs what it can take in, and the excess is passed out in the urine. There is nothing wrong; your body is simply getting rid of extra vitamin B2.
