Tirosint vs Levothyroxine: The Case for Switching Thyroid Medication

Tirosint is a T4 only thyroid medication but with some twists.

Many patients report significant improvement in hypothyroid symptoms when switching from T4 only medications like Levothyroxine and Synthroid over to Tirosint.

But how can that be? Especially when Tirosint is a T4 only medication?

This occurs for several reasons:

1) Inactive ingredients –

+ Levothyroxine and Synthroid contain MANY inactive ingredients (complete list in the video) which your body may be reacting to and limiting absorption. These inactive ingredients may be causing negative side effects that mimic hypothyroidism or limit your ability to reach the optimal dose.

Tirosint has 3 inactive ingredients and 1 active ingredient making it the “cleanest” thyroid medication (T4 only).

2) Decreased absorption –

+ Due to these inactive ingredients the absorption of Levothyroxine and Synthroid may be inferior to that of Tirosint. The fewer inactive ingredients means the more thyroid hormone that will be absorbed which means the better you symptoms will be. This is also very important for hypothyroid patients who have GI related conditions such as SIBO/SIFO, GERD and low stomach acid. Tirosint is more easily absorbed and utilized than other forms of thyroid hormone due to these reasons.

Who should consider using Tirosint?

– Patients with GI related issues
– Patients who don’t tolerate Synthroid or Levothyroxine
– Patients with multiple sensitivities or food allergies
– Patients with Leaky gut or increased intestinal permeability
– Patients who don’t tolerate T3 containing medications like NDT and/or liothyronine/cytomel
– Patients who are extremely sensitive to medications and supplements
– Patients who have experienced some improvement on Levothyroxine or Synthroid but still have room for improvement
