Thyroid hormones regulate metabolism, energy production, heart rate, body temperature, and cognitive function. Compounded thyroid preparations allow precise T3/T4 ratio customization that commercial levothyroxine alone cannot provide.
T4 (thyroxine) converts to the active T3 (triiodothyronine), which binds to nuclear receptors in virtually every cell, regulating gene expression for metabolism, energy production, and thermogenesis.
Many patients don't respond optimally to T4-only therapy. Compounding allows precise T3/T4 combinations, slow-release T3 capsules, gluten-free and dye-free formulations, and doses unavailable commercially.
Compounded thyroid hormones are prescribed on a patient-specific basis. The FDA has raised concerns about the consistency of compounded desiccated thyroid preparations. Patients should work with a knowledgeable thyroid specialist and monitor levels regularly with lab testing.
