What is Armour Thyroid?
(desiccated porcine thyroid gland)
Armour Thyroid is made from pork thyroid gland tissue. It contains thyroxine (T4) and triiodothyronine (T3), the two hormones your thyroid naturally produces. Unlike synthetic T4-only replacements, Armour provides both forms. Your body uses T4 as a reservoir; cells convert it to T3, the active hormone. Armour gives you both upfront, which some people find more effective for energy and mood.

How thyroid hormones work
Day 1
A US-licensed physician reviews your thyroid symptoms (fatigue, cold intolerance, weight, mood), medical history, and medications. Discusses how thyroid hormones work and the importance of lab-guided dosing.
1Week 1
Start with an initial dose (usually conservative) of your prescribed thyroid hormone, taken once daily in the morning with water on an empty stomach.
2Weeks 4-6
Thyroid hormones accumulate slowly; effects build over 4-6 weeks. Energy, temperature regulation, and mood may shift gradually. Keep a symptom journal.
3Week 6-8
First lab check: TSH and Free T4 (or Free T3 if on T3). Your physician adjusts dose if needed. Repeat this cycle every 6-8 weeks until TSH and symptoms align.
4Beyond
Thyroid hormones work best on a stable dose. Annual labs and check-ins ensure your dose stays right as your body and needs change.

The science of thyroid hormones
Armour Thyroid was the standard therapy before synthetic T4 became available in the 1960s. It provides both T4 and T3; some people tolerate it better than T4-only therapy.
Small studies suggest T4/T3 combinations can improve energy and mood compared to T4 alone in some people, though results are mixed. Your physician weighs this against lab values and symptoms at every check-in.
Learn moreImportant safety information and common side effects
Thyroid hormones regulate metabolism and affect every cell. Overdosing causes tachycardia, palpitations, anxiety, insomnia, and heat intolerance; underdosing leaves fatigue and brain fog. Thyroid hormones are not for weight loss in people with normal thyroid function. Do not use if you have uncontrolled high blood pressure, active angina, or untreated adrenal insufficiency. Tell your physician about all medications, especially beta-blockers, stimulants, and any cardiac history. Stop and seek care for rapid heartbeat, chest pain, severe shortness of breath, or signs of thyroid storm (high fever, confusion, agitation).

Frequently asked questions
How do I take Armour Thyroid?
Taken by mouth, once a day, in the morning. The starting prescription is 1 tablet (30 mg) each time. Your physician sets your own dose and it is printed on your label.
What strengths does Armour Thyroid come in?
The pharmacy carries 2: 30 mg, 60 mg. Your physician chooses which one you get.
How much arrives in each shipment?
30 tablets at the starting strength, shipped to your door from a licensed US pharmacy.
Is Armour Thyroid better than synthetic T4?
Not necessarily. Armour works well for many people; others do better on synthetic T4 or a T4/T3 combination. The key is dosing to your TSH and Free T3 levels, and adjusting until you feel well. Your physician chooses based on your labs, symptoms, and preference.
Why can't I feel my dose immediately?
Thyroid hormones accumulate in your tissues and bloodstream over weeks. The half-life of T4 is about 7 days, so it takes 4-5 half-lives (1 month) to reach steady state. Be patient; your physician will adjust if needed at your 6-8 week check.
Will thyroid hormone help me lose weight if my thyroid is normal?
No. Thyroid hormones are not weight-loss drugs. They work only in people with low thyroid function. Overdosing a person with normal thyroid function causes dangerous side effects (tachycardia, heat intolerance) without weight loss.
Can I adjust my dose myself?
No. Thyroid dosing requires lab values (TSH, Free T4, Free T3) to be safe and effective. Too much causes palpitations and anxiety; too little leaves you fatigued. Your physician adjusts by the numbers and your symptoms, never by guessing.
What if T4 alone does not work for me?
Some people need T3 added or prefer a T4/T3 combination or natural desiccated thyroid. Your physician will try adjusting the T4 dose first, then explore other formulations if needed. This takes patience and close communication.
