Okay, new question. Has anyone on here even HEARD of PreKUnil? I’m curious because it seems that not many people have. The reason this may be is because it is really something for people like me, who are older and don’t think that they can stick to the diet. Also, it cannot be used if you ever plan to get pregnant. (which I do NOT) What PreKunil does is keep the effects of higher phe levels from damaging your brain, but it does NOT lower phe levels in the blood. Which is why it would still be damaging to an unborn child. This is something that males with PKU should look into, and also females with no plans of ever having kids.
