Discover the benefits of Tiromel and Bitiron for thyroid health. Tiromel, a synthetic thyroid hormone, includes liothyronine sodium that T3 closely resembles the body's own triiodothyronine (T3). The thyroid gland naturally secretes T4 and T3, but Tiromel's synthetic T3 provides a stronger and faster-acting alternative, enhancing metabolic regulation more effectively than traditional L-thyroxine (T4).
