Desiccated thyroid extracts (DTE), such as Armour® Thyroid, NP Thyroid® and Nature-Throid®, are natural preparations derived from porcine (pig) thyroid glands. One grain of thyroid contains 38 micrograms (mcg) levothyroxine and 9mcg liothyronine per 65mg of the labelled amount of thyroid (5-7), but this can be variable between batches. ................
