Hypothyroidism - Choosing the right thyroid hormone

There are many underlying metabolic causes behind poor thyroid function. These include male and female hormones, gluten sensitivity, candida infection, leaky gut, small intestinal bacterial overgrowth (SIBO), nutritional imbalance, adrenal fatigue, chronic stress, liver dysfunction and medications.
Addressing all of these areas give the patient suffering with thyroid disease the best chance at correcting the underlying cause of thyroid disfunction.

There are quite a few options for thyroid medications for hypothryoidism. Our bodies will not all react the same to these different medications. Finding the right thyroid medication can take some experimenting with the help of your doctor.

Below is a list of common medications used to treat or reduce the symptoms of Hypothyroidism.

T4 Drugs
Brand names : Synthroid, Levothroid, Levoxyl, Unithroid
These drugs contain the synthetic form of one thyroid hormone, the levothyroxine T4. They also have different fillers and binders, so people may have different allergic responses to the different brands.

T4 Drugs
Brand name Tirosint
The synthetic levothyroxine T4 in Tirosint is in a liquid form inside a capsule. Tirosint has no fillers.

T3 Drugs
Brand name Cytomel (synthetic).

Bio-identical thyroid hormones
Brands names Armour (T3/T4), Nature-throid (T3/T4) and Westhroid (T3/T4).

When choosing the appropriate thyroid hormone, three factors must be considered:
  • Sensitivity to fillers: Some people are sensitive to the dyes and fillers in thyroid hormone medications. For example, patients who know or suspect that they are sensitive to Synthroid tablet fillers may try switching to Tirosint Gelcaps.
  • Bio-identical versus synthetic hormones: sometimes receptor sites on cells simply respond better to bio-identical than synthetic hormones
  • Difficulty converting T4 to T3: People who have difficulty converting T4 to T3, do better with thyroid hormones that include T3.
