IODINE:

There is a large amount of information that investigates the effect of excess iodide on the thyroid and the link between excessive iodide exposure and the development of autoimmune thyroid disease in susceptible individuals. Autoimmune thyroid disease can result in hypothyroidism or hyperthyroidism (associated with Graves’ disease).These effects have been assessed in the Agency for Toxic Substance and Disease Registry review of iodine (ATSDR, 2004)
