Thyroid hormones (thyroxine and T3) are produced by the thyroid gland. They have diverse actions and they act on nearly every cell in the body to regulate the body’s metabolism, energy levels and its sensitivity to other hormones in the body, such as estrogen, testosterone and progesterone. They play an important role in temperature regulation and muscle contraction. Some people experience thyroid dysfunction which can result from the thyroid gland being underactive, known as hypothyroidism, or overactive which is known as hyperthyroidism.
