Armour thyroid (thyroid tablets, USP) is a product derived from porcine thyroid glands. Each grain contains 38 micrograms of levothyroxine (T4) and 9 micrograms of liothyronine (t3). Inactive ingredients are
calcium stearate, dextrose, microcrystalline cellulose, sodium starch glycolate and opadry white. Armour Thryoid is a product of Forest Pharmaceuticals that is used as a naturally derived alternative to synthetic thyroid hormone replacement therapy using products such as levothyroxine.
Armour thyroid is made by taking a porcine thyroid and using the whole organ intact, it is ground up into powder form.
