I would agree with Lori that you can't just give up your thyroid medication until your thyroid heals. Try your pharmacy first to see if they can find a formulation that doesn't contain the corn products. If that is not possible, look for a compounding pharmacy and see if they can make the medication to order. They can leave out the harmful “inactive” ingredients. Even small amounts of gluten can trigger an inflammatory response that will delay your eventual goal of total health.
