Iodine is necessary for the production of T 3 and T 4. A deficiency of iodine leads to decreased production of T 3 and T 4, enlarges the thyroid tissue and will cause the disease known as simple goitre. The major form of thyroid hormone in the blood is thyroxine (T 4), which has a longer half-life than T 3.In humans, the ratio of T 4 to T 3 released into the blood is roughly 20 to 1. T 4 is converted to the active T 3 (three to four times more potent than T 4) within cells by deiodinases (5'-iodinase).odine is necessary for the production of T 3 and T 4.
