damage during stages of fetal development and lactation. The safety of therapeutic doses of iodine above the established safe range of 1.0 mg may be evident in the lack of obvious toxicity in the Japanese population that consumes 25 times the median intake of iodine consumption of the
United States. The Japanese population suffers no demonstrable increased incidence of autoimmune thyroiditis or hypothyroidism. Studies using 3- to 6-mg doses to effectively treat fibrocystic breast disease may reveal an important role for iodine in maintaining normal breast tissue architecture and function. Iodine may also have important antioxidant functions in breast tissue and other tissues that concentrate iodine via the sodium iodide symporter.
L-tyrosine is an amino acid necessary for the synthesis of thyroxine (T4) and triiodothyronine (T3). In the process of thyroid hormone synthesis, iodine binds to two positions on the tyrosyl ring of tyrosine. Thus, a deficiency of this important amino acid could contribute to low thyroid hormone
levels. Studies have found tyrosine may be beneficial for treating fatigue, a common symptom of low thyroid. Iodine is necessary for the formation of T4, but appears to have no affect on peripheral conversion of T4 to T3.
Goitrogenic foods can cause a relative iodine deficiency by binding to iodine, making it inaccessible for thyroid hormone synthesis. Cooking these foods tends to make them less goitrogenic. Common goitrogenic foods include broccoli, cauliflower, cabbage, Brussels sprouts, kale, soy, peanuts
and pine nuts, turnips, and rutabaga.
