The most frequent question asked by a patient suffering from hypothyroidism is, “what is the difference between armour thyroid and Synthroid, which is more effective.” Even though both medicines are meant to replace the thyroid secreted hormones, they are different substantially.

What is Hypothyroidism and how is it treated?

Hypothyroidism means underactive thyroid gland. The basic function of the thyroid gland is to secrete thyroxine (T4) and triiodothyronine (T3). The thyroid gland is stimulated by the Thyroid-stimulating hormone, produced by the hypothalamus. Hypothyroidism is most importantly measured by the amount of TSH secretion in the body.

The two most famous medications for hypothyroidism include Armour Thyroid and Synthroid. But which among them is better for treatment exactly and how can it be proved? Let’s compare and find it out.

Armour Thyroid

Armour thyroid is a non-synthetic medication. It contains desiccated Thyroid extracts. Usually, it is made of dried and powdered Thyroid, from pigs. It has both T4 and T3 hormones in a ratio of 80:20. Because of this mixture, most doctors are switching to a synthetic form of treatment.

Difference between Armour thyroid and Synthroid

  1. Synthroid is a synthetic hormone identical to human’s T4 hormone. Whereas, armour Thyroid contains Thyroid extracts from pigs. Hence, it is not identical to the human form.
  2. Armour thyroid is a natural desiccated hormone derived from a pig. On the other hand, Synthroid is prepared in the laboratory.
  3. Synthroid contains only T4 hormone and armour contains both T4 and T3.
  4. Synthroid is very unlikely to trigger an autoimmune response in a patient having Hashimoto’s thyroiditis. Thus people with Hashimoto feel comfortable with synthetic medication and not with armoured thyroid.
  5. Armour thyroid acts a bit faster, unlike Synthroid. On one hand, Synthroid takes around 4 weeks to show any change in your lab report whereas armour alters your lab report in 2 weeks.
