Iodine and Hashimoto's

Q: I am 59 years old and have been taking Levothyroxine since I was approximately 30 years old. Recently, a new doctor put me on Armour Thyroid (75 MG). Last year, a blood test showed that I have Hasimoto's. I am confused about your recent post about iodine. If taking iodine can lead to Hashimoto's, what about taking it after you already have it? Why would that be beneficial if it can actually cause hypothyroidism?  A: First of all, since you were diagnosed with hypothyroidism at age 30, you have likely been suffering from Hashimoto's thyroiditis since that time as well. Hashimoto's is the thyroid inflammation that leads to hypothyroidism and the need for thyroid hormone replacement. As far as iodine is concerned, the article states that taking too much, or overdosing, on iodine can lead to Hashimoto's. Not taking enough (iodine deficiency) is bad for the thyroid as well. Therefore, a balanced amount of iodine must be taken. Thyrolife Optima contains 140 mcg of iodine which is a sufficient amount for the average person to take daily. Some alternative doctors recommend Iodoral, a supplement that contains 50 mg iodine (300x the recommended amount), which can lead to iodine overdose. We are encouraging people to stay away from these types of supplements because although they are marketed as for "thyroid support," they are often detrimental.
