I take a multi-vitamin supplement about 5 days a week. What is it in the pill that makes my urine turn bright, bright yellow? It looks almost fluorescent sometimes!
Could be...I was certain on the B vitamin part, but since I've never seen any of the B vitamins individually, just as a complex, I could very well be wrong on which one it is that's the yellow culprit.Does folate have a visible chromaphore? I always thought that color was due to the bright yellow riboflavin (B2).
