Are you sure that those products contain gluten? I've used Armour consistently for two years without problems, and the Armour web site says their product is gluten-free.
Actually, I just found out that what the pharmacies have been passing off as the "new Armour" is actually NP Thyroid and not made by the same company at all so
Armour made by Forest is still okay but NP Thyroid made by Acella DOES contain gluten. The 60mg tablets have an AP on one side of them and 330 on the other side and Real Armour only has an A stamped on it. Yes Synthroid does contain gluten now.
