I have been currently taking 3000 mg of vitamine c a day. I jus recently added vitamine b-5 at 3000 mg a day also; and i am not taking any other supplement's or gear. I have noticed that my urine is neon yellow, this freaked me out at first. I think it is the vitamine b-5. i drink about a gallon and a half of water a day so i know that i am drinking enough water. have any of you bro's ever had this happened while taking vitamine b-5 ?
