Question: which one of the following is required in the diet in order for active thyroid hormones?
Answer: Your thyroid makes 2 main hormones – triiodothyronine (T3) and thyroxine (T4). Adequate amounts of iodine (a chemical element that's an essential part of our diet) are needed for the thyroid to be able to make these hormones. Another hormone that's produced in your thyroid gland is called calcitonin.
