Thyroxine

Thyroxine, also known as T4, is a hormone produced by the thyroid gland, located in your neck. It plays a vital role in regulating your body's metabolic rate, which influences how fast your cells work. Thyroxine helps control energy levels, body temperature, and overall growth and development. It is converted into a more active form called T3 in tissues throughout your body. Proper levels of thyroxine are essential for maintaining overall health, and imbalances can lead to conditions like hypothyroidism (low levels) or hyperthyroidism (high levels), affecting your metabolism and energy.
