Why Should I Take A Desiccated Thyroid Or Compounded Thyroid? Why should I take a desiccated thyroid or compounded thyroid instead of Synthroid? To answer this question it is important to explain the difference between T4 and T3. T4 is a prohormone. When a patient is given a medication that contains only T4- such as Synthroid, Levoxyl, Levothyroixine, Tirosint- the practitioner is hoping that the patient’s body is going to naturally convert this T4 prohormone into the active hormone called T3. Unfortunately, not everyone does this very well. Visit Here: https://abhormonetherapy.com/why-should-i-take-a-desiccated-thyroid-or-compounded-thyroid-instead-of-synthroid
