Alright so recently i bought gnc's multivitamin "mega men," because well i never have ever taken vitamins of any kind, so why not start. The directions say take 2 with meal, I did that, drank plenty of water and my urine was a ridiculous neon yellow. Some say its just cleaning my system but is that true? I would think its more my kidneys getting overloaded with vitamins and spitting em out, which isnt good to over work them. I talked to my friend and he suggested only taking one pill, the problem was improved but still, its kind of alarming so i've stopped taking them. Advice?
