Thyroxine (T4) is the primary hormone that is produced and secreted by the thyroid gland. It is responsible for digestion, heart rate, muscle formation, brain development, and healthy bones. T4 is biologically inactive (called a storage hormone); its primary function is to transport the hormone triiodothyronine (T3) to the proper organs in your body.

When T4 gets into the cells of the body, it loses one molecule and becomes T3. Thyroid function tests that check both TSH and T4 levels are the most accurate ways to diagnose thyroid conditions.

One of those hormones is thyroxine, also known as T4. Because of the many functions that thyroxine impacts, it is considered one of the most important thyroid hormones. Thyroxine (T4) is a hormone produced by the thyroid gland. It is sometimes called total thyroxine because it includes both free T4 and T4 bound to proteins. Thyroxine is only one-tenth as potent as the other major thyroid hormone, triiodothyronine (T3).
