I'm on Armor thyroid (180 mg) and have very high T3 (11.0 pg/ml) and the range is 2.3-4.2 pg/ml. I also have low normal T4 (.90) and the range is .89-1.76 pg/ml. I'm not losing weight even when exercising 5 days a week. I've read that sometimes the T3 doesn't get into the cells because of low adrenal function or low iron or Iodine. How can I tell what the cause is and any ideas on what to do?
