Three iodine molecules are added to make T3 (triiodothyronine), and four for T4 (thyroxine) -- the two key hormones produced by the thyroid gland -- so iodine is essential to the production of these two hormones of the master gland of metabolism.

Less severe iodine deficiency is linked to hypothyroidism, thyroid enlargement (goiter) and hyperthyroidism.
