That is good to know also. My own doctor in California actually prescribed bioidentical hormones, but I am very sensitive and when they couldn't get my thyroid in order I finally gave up. They actually first started me on armour thyroid which is porcine derived. It is the one that made me sick. Then we tryed synthroid, it worked ok, but right away I needed it up and there was confusion with the generic versus the brand name and mg amount and I personally gave up trying to get it right. I suppose I should start again with my GP so he can help. He has gone to more alternative ways, at least that will be a start.
Thanks for the info it is a wonderful help, it all makes sense.
