Yeah, most docs I think have to officially say 'ney' because it's not FDA approved. At least not the supplement, non injectable form. Luckily my doc acknowledges that all Western medicine is based on nature. He can't officially prescribe it, but he can't nod his head lol. Good luck to you - I think you'll be pleasantly surprised.
I know there's a lot of variation in quality - I started with Source Naturals, which I like - but will probably switch to GNC's as it's supposed to be 'the best'.
