What brand of b vitamins do you take and how many do you need to take a day if I'm using puritan's pride? (I'm taking the pp biotin, are b vitamins essential for biotin to work?)
I take PP biotin along with Twinlab's b5 (500). I also take a liquid b complex, I can't remember the name of the brand, but I think it has greatly improved the results I get from taking the PP biotin.
