Is anyone else out there on Bettermilk? That's Cambrooke Food's GMP formula. I have been taking it for about 3 months and I really like it. It actually tastes really good. I tried Kuvan and was not a responder. I have heard that Bettermilk stabilizes and even lowers phe levels in some people. I definitely have better appetite control on it, and it does seem to stabilize my moods. I'm not as emotional, even though I'm probably eating a little more phe than I should every day (each packet has 23 mg of phe, and I have to take 4 or 5 a day). I'm only allowed 350 mgs of phe per day. I haven't done a level to confirm this yet, which I probably should. Just wondered about other people's experiences.
