I'm having that dilemma right now and I actually started a thread about what to do: http://forums.phoenixrising.me/inde...r-supplements-or-nothing-save-my-money.23390/ Ok, it seems that you did tell me about phenylalanine. So is it different than L-phenylalanine? In the description it says a small portion will be converted into L-phenylalanine which I guess is ok. My concern is that it could lead to high norepinephrine since it's a tyrosine precursor, but maybe the D-form won't cause those problems. One customer review said they didn't feel wired from it like L-phenylalanine so maybe it will be ok. There's a sale on iron bisglycinate at Vitacost so maybe I'll take that and the milk thistle. Somehow I remember reading milk thistle can also raise glutathione. If that is what's going on with me will lactoferrin modulate that response?
