American Thyroid Association Recommends Against Iodine Supplementation

[Nelson Vergel]

"...ingestion of more than 1,100 µg iodine per day is not recommended and can cause thyroid dysfunction. The recommended daily allowances of iodine intake in the United States are 150 µg for adults, 220 µg to 250 µg for pregnant women and 250 µg to 290 µg for women who are breast-feeding.Some supplements, including iodine, potassium iodide and kelp, can contain iodine amounts that are several hundred times higher than the recommended daily allowance, and people are advised not to take an iodine or kelp supplement containing more than 500 µg of iodine daily."
