Active Ingredient

Tiratricol (3,3',5-triiodothyroacetic acid) is a naturally circulating metabolite of active thyroid hormone (T3) with a high degree of structural similarity and follows the same downward degradation pathway (deiodination and conjugation) and elimination via bile and urine. Tiratricol has been demonstrated to be able to enter MCT8 dependent cells without a functioning MCT8 transporter unlike T3 and T4. Tiratricol can thereby replace T3 in MCT8 dependent tissues and restore normal thyroid hormone activity across tissues.
