Hi, I have been lurking for a while now, and saw that everyone raved for puritan's pride megavitamins. I began taking them this past weekend, and I noticed change in urine color. I read this was simply the body excreting extra vitamins B2. I have been takin 5(as I have seen recommended)a day, and was wondering if anyone has noticed any other adverse effects. Me being paranoid with pills like I am do not wanna start attributing changes in how i feel to the pills & stop taking them. Thanks for ur help you guys!
