Liothyronine (T3) and Levothyroxine (T4) are the two most commonly used thyroid ingredients. 

​

Commercially available products are only available in certain strengths. Our process uses individual powders of each ingredient that allows for full customization of your thyroid dose.

​

In accordance with our commitment to high quality standards, all thyroid ingredients are mixed and then independently verified by a third party lab to ensure proper potency. This way you can feel confident that you're receiving the right strength for your unique needs.
