Hi Lorena, I can't be much help about Armour, but I do know a group that can give you loads of help and advice about thyroid, as I have noticed that there doesn't seem to a large amount of traffic on this section, so you may have to wait a while for some info :

If it's not ok to give out the address on the site, can someone cut it please?

http://groups.yahoo.com/group/thyroidwtloss

It is a support group for thyroid suffers who are tying to diet and they all seem convinced that low carb is the way to go for thyroid weight problems, so there will not be any conflict with this forum.

Let me know how you get on.
