Dear sir, it is not good to take only T3 (liothyronine) for low thyroid? And why you prefer T4?

T3 (liothyronine) or T4. T4 is the major thyroid hormone in the blood and a small fraction is also converted to T3 (liothyronine). T4 is preferred. Adding T3 (liothyronine) tablets adds more cost and limited extra value. Sometimes T3 (liothyronine) is necessary but not often.
