What Does T4 Stand For?

T4 stands for Thyroxine

T4, or thyroxine, is a hormone produced by the thyroid gland that plays a critical role in regulating metabolism, growth, and development in the body. It is vital for maintaining energy levels, temperature regulation, and overall physiological function. T4 circulates in the bloodstream and can be converted into its more active form, T3 (triiodothyronine), to exert its effects on various tissues and organs. Adequate levels of T4 are essential for proper metabolic processes and overall health.
