I am still waiting for my Nature-throid to arrive but just to let you know of the information I have found at:  http://rlclabs.com/aboutUs.asp

RLC Labs, Inc supply Nature-ThroidTM, and claim that they provide the only hypoallergenic medication with a history of safety, efficacy, and consistent T3 and T4 content unmatched by anyone in the industry. 

I can not wait to try it, if it works as good as the old Armour did I'll be happy but I have a feeling it may be better as RLC concentrate of providing thyroid care! Check out their web site for yourself.  If any one has tried it I would love to hear your views.  Denise
