With my long struggle, I found myself on thyroid support groups and I'd say MOST that I trusted believed in Stop The Thyroid Madness book and the author's blog...there was a forum, realthyroidhelp.com (I think) and so many used desiccated thyroid ... this group had to fold due to lack of funds to keep it running, but it was a good one and I've missed it.

I don't know if Nervous has done anything yet, and I have known friends who were on Syn for some time and thought they were doing ok, and then got on desiccated and felt much better....So there are other options out there....I've also heard that some don't convert T3 and T4 ... another friend of mine who is now 87, did acupuncture for many many years and the doc worked on her thyroid, she takes no thyroid meds.. Good chance she could use some now, but she doesn't bother, she has so many other issues.

I'd say MOST integrative and naturopath MD's use desiccated. More natural substance.
