I just started meds for hyperthyroidism but am also taking a multivitamin supplement which contains 200mcg of iodine per tablet. is the iodine too much and is it ample to affect my thyroid treatment?

I answered this before, however there are indications that in some people 200 mcg of iodine may not be handled well in hyperthyroidism so it is not a simple answer it is okay to take the supplement. It may not be helpful to take iodine at such a level with hyperthyroidism especially since there are other sources of iodine in the food. Discuss with your provider next appointment.
