Hi, My tests came back and my Thyroid Panel(TSH, T4, T3, Reverse T3) were all fine (mid range) However, Urine Iodine was on the lower side 45.1 (Range 28 - 544) Dr. Suggested I take Iodine and I did , but gave me severe headaches. My questions are : 1. Can Iodine deficiency alone cause symptoms of fatigue and low energy? 2. Is there a transdermal form of Iodine that works well for Iodine deficiency? Reason I ask is I am very susceptible to headaches when I take supplements by mouth, but injections and sometime creams and sprays bother me less. Thanks so much.
