The medical use of desiccated* natural thyroid began in the late 1800s.

The USP issued identity and purity standards for “thyroid gland dessicated” 
                 since 1900. Current synthetic T4 compound was developed in the early 1950s. CR Harrington isolated T4 in 1927. Braverman et al 
                 discovered that circulating T3 is largely derived from enzyme conversion of T4 outside of thyroid.

The US rights to Armour® Thyroid were acquired by Forest Laboratories in 1990. Armour® Thyroid became an Allergan product with the merger of Forest Laboratories into Allergan in 2014-2015.

Hypothyroidism:
It’s not just about T4

Armour® Thyroid contains both thyroxine (T4) and triiodothyronine (T3), a second hormone produced by the thyroid gland. T3 has more than 4 times the activity of T4 in the body.

Armour Thyroid supplements both T3 and T4 hormones.
Your body uses T4 to make T3.

Your body uses T4 to make T3

Your thyroid gland produces 13-15 times more T4 than T3. Cells throughout your body then convert T4 to T3 for their use. That’s why hypothyroidism is often treated by replacing T4 alone. However, some people have trouble converting T4 to T3.

A natural thyroid preparation, formulated for consistency

Armour® Thyroid is a natural preparation, derived from the thyroid glands of pigs raised for human consumption. Each tablet of Armour® Thyroid provides 38 mcg T4 and
9 mcg T3 per grain. The hormones contained in the natural preparation are absorbed similarly to synthetic hormones.

IMPORTANT RISK INFORMATION

Thyroid hormones, including ARMOUR THYROID, should not be used either alone or in combination with other drugs for the treatment of obesity or weight loss. In patients with normal thyroid levels, doses of ARMOUR THYROID used daily for hormone replacement are not helpful for weight loss. Larger doses may result in serious or even life-threatening events, especially when used in combination with certain other drugs used to reduce appetite.

WHAT IS ARMOUR® THYROID?

ARMOUR THYROID (thyroid tablets, USP) is a prescription medicine that is used to treat a condition called hypothyroidism from any cause, except for cases of temporary hypothyroidism, which is usually associated with an inflammation of the thyroid (thyroiditis). It is meant to replace or supplement a hormone that is usually made by your thyroid gland.

ARMOUR THYROID is also used in the treatment and prevention of normal functioning thyroid goiters, such as thyroid nodules, Hashimoto’s thyroiditis, multinodular goiter, and in the management of thyroid cancer.
