Interaction warnings
Liothyronine + calcium
moderateCalcium salts (carbonate, citrate, acetate) can bind thyroid hormone in the gut and reduce absorption of liothyronine (T3), much as they do with levothyroxine. Taking them together can blunt the effect of the dose and lead to less reliable thyroid replacement.
Liothyronine + iron
moderateIron salts (ferrous sulfate, fumarate, gluconate, bisglycinate) can bind thyroid hormone in the gut and reduce absorption of liothyronine, similar to the well-documented interaction with levothyroxine. Taking them at the same time can blunt the T3 effect and let TSH drift upward.
