Armour vs. Other Brands
- ARMOUR is made by Forest Pharmaceuticals. It is made in the following strengths: 1/4, 1/2, 1, 2, 3, 4 and 5 grain tablets. One grain is 60 mg and contains 38 mcg. of T4 and 9 mcg. of T3, plus unmeasured amounts of T2, T1 and calcitonin. The latter three are not removed, as rumor occasionally states. Each tablet contains:
- Porcine Thyroid Powder, U.S. Pharmacopeia
- Dextrose (sugar–allows you to do it sublingually)
- Microcrystalline Cellulose
- Sodium
- Calcium Stearate (stabilizer and lubricant)
- Opadry White (Titanium dioxide, but also contains trace amounts of PEG (polyethylene glycol), Polysorbate 80, and Hydroxypropyl Methycellulose. See below.)
- Porcine Thyroid Powder, U.S. Pharmacopeia
- Microcrystalline Cellulose
- Dicalcium Phosphate
- Sodium Starch Glycolate
- Magnesium Stearate
- Hydroxypropyl Methylcellulose
- Stearic Acid
- Carnauba Wax
- Polyethylene Glycol
***Hormonally, Armour and Westhroid and Nature-Throid are absolutely identical–their Thyroid powder meets the same USP guidelines. Armour has less ingredients than both Westhroid or Naturethroid. Microcrystalline Cellulose is technically what makes a product hypoallergenic, but if you have an severe allergy to corn, Dextrose aka Glucose may be a derivative of cornstarch.

- Sodium starch glycolate (helps dissolute/disintegrate the pill)
- Magnesium stearate (filling agent)

The generic thyroid above is often made in 65 mg. tablets (as compared to 60 mg. of the brand names). They are coated. For some reason, they may be less effective than the name brands, say some users, so you have to take more. Another generic maker is called URL, or United Research Labs, which is a sister company to Mutual Pharmaceutical. As of 8-07, it’s reported by a patient that Qualitest now has the same smell as Armour, which is different than the lack of smell it had before.
- Whole Dessicated Thyroid Glandular Concentrate - Porcine
- Raw Porcine Thyroid Tissue 130 mg.
- Dicalcium Phosphate
- Magnesium Sterate (Natural Tableting Agent)
Patients report that over-the-counter thyroid products, including Nutri-meds, are FAR weaker than all the above. Yes, they may be good in a pinch for help, but not for long term support.
This bible of hypothyroid treatment contains most everything you will find on this site, plus a whole lot more, including a chapter on T3, an explosive doctor chapter, historical information on desiccated thyroid as well as T4, an entire chapter on the TSH (Thyroid Stimulating Hooey), how to interpret your cortisol labs, extra details in two adrenal chapters, and more!

INGREDIENT EXPLANATIONS:
- Microcrystalline Cellulose
- synthetically derived fiber base (similar to plant-derived). It is typically utilized as a filler in a tablet (to provide volume and bulk).
- Dicalcium Phosphate
- derived from a mined ore. It is typically utilized as a binder in a tablet (to hold all the ingredients during compression).
- Colloidal Silicon Dioxide
- derived from a mined ore. Typically utilized as a natural desiccant in a tablet (to provide barrier from moisture and humidity).
- Sodium Starch Glycolate
- Synthetically derived starch molecule (similar to potato starch). It is typically utilized as a disintegrating agent in a tablet (to aid in proper disintegration of the tablet in the stomach).
- Magnesium Stearate
- Derived from a vegetable source (typically palm oil). It is typically utilized as a lubricating agent in a tablet (to aid in proper compression of the tablet).
- Hydroxypropyl Methylcellulose
- Derived from a plant cellulose base (typically cotton blend or wood pulp). It is typically utilized as a granulating agent in a tablet (to provide bulk and density to the tablet for proper compression) as well as part of a clear coating solution (with PEG).
- Polysorbate 80
- An inactive water soluable emulsifying agent which blends the ingredients of mixtures and prevents separating.
- Stearic Acid
- Derived from a vegetable source (typically palm oil). It is typically utilized as a binder in a tablet ( to hold all the ingredients during compression).
- Carnauba Wax
- Derived from the pores of the leaves of the Brazilian wax palm tree. It is utilized in the final stage in tablet coating (to provide a complete seal).
- Polyethylene Glycol (PEG)
- Synthetically derived, water-soluble, waxy solid. It is utilized with Hydroxypropyl Methylcellulose as part of the clear coating solution.
- Lactose Monohydrate
- Present in traceable amount as part of Thyroid USP (diluent)
