Please note, all doses of Armour Thyroid remain available and are no longer on back order.

Armour Thyroid is a natural, porcine-derived thyroid hormone replacement containing both T4and T3.

Note that the amount of thyroid hormone in the thyroid gland may vary from animal to animal. To ensure that Armour Thyroid tablets are the same from tablet to tablet and lot to lot, the amount of T4 and T3 is measured in both the raw material and in the actual tablets.

Should you have any questions about the product, please call 1-866-927-3260.

If you think you may suffer from thyroid disease, you should see a doctor as soon as possible. This site is not intended as a substitute for the advice of a doctor or other qualified healthcare professional.

Important Safety Information Thyroid hormone should be used with caution in patients with angina pectoris or the elderly, in whom there is a greater likelihood of occult cardiac disease. In these patients, therapy should be initiated with low doses, i.e., 15-30 mg Armour Thyroid. The development of chest pain or other exacerbation of cardiovascular symptoms will require a decrease in dosage. Thyroid hormone may increase symptoms of diabetes mellitus, diabetes insipidus, or cortical insufficiency. Appropriate adjustments of the various therapeutic measures directed at these concomitant endocrine diseases are required. Dosages of oral anticoagulants should be adjusted in thyroid-treated patients on the basis of frequent prothrombin time determinations. Caution should be used in infants where excessive doses of thyroid hormone preparations may produce craniosynostosis.
