What hormones do the thyroid gland produce?

The thyroid gland makes two thyroid hormones, T3 (triiodothyronine) and T4 (thyroxine), produced by the follicular cells and dependent on iodine. These hormones set the body's metabolic rate and support growth and development. In addition, the thyroid contains parafollicular C cells that produce calcitonin, which helps regulate calcium by inhibiting osteoclast activity in bone. So the thyroid’s hormonal output includes T3, T4, and calcitonin. TSH comes from the pituitary and stimulates the thyroid, while parathyroid hormone comes from the parathyroids, not the thyroid.
