Since levothyroxine already contains
Levothyroxine tablets combined with iodine-131 for thyroid cancer patients undergoing radical thyroidectomy effectively could improve the treatment efficiency, reduce the risk of
It's complicated, but that tiny amount of iodine is needed in the process of converting your levothyroxine/T4 (inactive) to T3, which is the bio-available (usable)
