What Is Thyroxine (T4) And Triiodothyronine (T3)?
Share
Thyroxine (T4) and triiodothyronine (T3) are hormones produced by the thyroid gland, a small butterfly-shaped gland located in the neck. These hormones play a crucial role in regulating the body's metabolism, which is the process of converting food into energy. T4 is the more abundant hormone, but T3 is more active and potent in influencing metabolic processes. Together, they help control heart rate, body temperature, and how quickly the body uses energy. Proper levels of T3 and T4 are essential for maintaining overall health and well-being.
