Levothyroxine T4 (0.2mg/60caps)

A synthetic levo-isomer of thyroxine, levothyroxine (T4) serves as a precursor to triiodothyronine (T3), the active form that is engaged in biochemical and metabolic activities. To control enzymatic pathways related to energy use, protein interactions, and molecular signaling, T4 is deiodinated. This substance has a high plasma protein binding (~99%), mainly interacting with albumin-like structures, transthyretin, and thyroxine-binding globulin (TBG). Deiodination, conjugation, and oxidative deamination are the metabolic routes that involve excretion mechanisms and enzymatic reactions.
