Armour Thyroid 1 1/2 Grain (90mg)

Armour Thyroid general information

What is Armour Thyroid used for?

Armour Thyroid 90mg tablets are used to treat hypothyroidism or underactive thyroid, a condition in which the thyroid gland does not make enough thyroid hormone needed to regulate your body’s growth and metabolism. Armour Thyroid 90mg tablets are a natural replacement hormone, derived from pig thyroid gland, containing both forms of thyroid hormone (T3 and T4), which help to relieve the symptoms of hypothyroidism, including, tiredness, muscle weakness, cramps, feeling the cold, a slow heart rate, dry and flaky skin, hair loss, a deep husky voice and weight gain. Armour Thyroid 90mg tablets can also be used to help treat hypothyroidism caused by surgical removal of, or damage to the thyroid gland, as well as treating thyroid goitre (enlarged thyroid glands) and thyroid cancer. Another used for Armour Thyroid 90mg tablets is for a suppression test, to test for thyroid activity.

How does Armour Thyroid work?

Armour Thyroid 90mg tablets consist of an extract produced from pig thyroid glands which contains both forms of thyroid hormone; thyroxine (levothyroxine or T4) and liothyronine (L-triiodothyronine or T3). Thyroxine (T4) is converted to the more active form of thyroid hormone (T3) in the liver, kidney and other tissues of the body and T3 interacts with a specific receptor inside cells to stimulate proteins needed to manage and control a variety of processes, including how the body regulates temperature, metabolises nutrients and controls growth and development. Thyroid hormones regulate the production by the pituitary gland of another hormone called thyroid stimulating hormone (TSH), which in turn controls how much thyroid hormone is produced. Armour Thyroid 90mg tablets regulate TSH production in the same way and this is how it works when used for treating thyroid goitre or thyroid cancer by suppressing TSH production.

What does Armour Thyroid contain?

Armour Thyroid 90mg tablets contain a dessicated (dried) extract of pig thyroid glands, which contains both forms of thyroid hormone; thyroxine (levothyroxine or T4) and liothyronine (L-triiodothyronine or T3) in the ratio 4.22:1 of T4 to T3, as T3 is approximately four times as potent as T4 on a microgram for microgram basis. Armour Thyroid 90mg tablets also contain dextrose, anhydrous microcrystalline cellulose, sodium starch glycolate, calcium stearate, opadry wehite (titanium dioxide used as a whitening agent)

Treating underactive thyroid (hypothyroidism) with Armour Thyroid

Armour Thyroid 90mg tablets consist of an extract produced from pig thyroid glands which contains both forms of thyroid hormone; thyroxine (levothyroxine or T4) and liothyronine (L-triiodothyronine or T3) and substitutes for the lack of thyroid hormone in hypothyroidism (underactive thyroid gland) needed to regulate normal growth and metabolism. Armour Thyroid 90mg tablets are used to treat the symptoms of hypothyroidism, including, tiredness, muscle weakness, cramps, feeling the cold, a slow heart rate, dry and flaky skin, hair loss, a deep husky voice and weight gain.

What is the difference between natural and synthetic thyroid hormones?

Armour Thyroid 90mg tablets contain an extract produced from pig thyroid glands which contains both forms of thyroid hormone; thyroxine (levothyroxine or T4) and liothyronine (L-triiodothyronine or T3). These hormones are therefore natural hormones compared to synthesised hormones found in some other preparations of thyroid medication. Both natural and synthetic hormones work in the same way to treat thyroid disease.
