Mechanism of action

Armour Thyroid is a natural desiccated thyroid extract containing both thyroxine (T4) and triiodothyronine (T3) in a ratio approximating the natural thyroid secretion. These hormones bind to thyroid hormone receptors in target tissues, increasing metabolic rate, thermogenesis, and protein synthesis. It is used as replacement therapy in hypothyroidism to restore normal thyroid hormone levels and alleviate symptoms of thyroid deficiency.
