Which two main hormones are released by the thyroid gland?

The two main hormones released by the thyroid gland are thyroxine (T4) and triiodothyronine (T3).12

These hormones are synthesized within the thyroid follicles from the protein thyroglobulin, which serves as both a structural scaffold and a storage form for the hormones. The production process involves the uptake and attachment of iodine to the amino acid [tyrosine]. While the thyroid gland secretes significantly more thyroxine than triiodothyronine, thyroxine often functions as a precursor that is converted into the more biologically active triiodothyronine in various body tissues.312
