I will be honest with you I had thyroid cancer many many years ago and I remember then we did not use armour because it was not consistent the way it worked according to my endocrinologist. You can always get another opinion from another endocrinologist . if it were me I wouldn’t want to make sure that my thyroid numbers are correct and consistent and I would want to use regular thyroid medication’s. I really hope I was able to help you out! Very best wishes to you going forward!!!
