The main value of T4 is to be converted to T3. Only the T3 thyroid hormone binds to the nuclear thyroid receptors, as it is the active thyroid
The active drugs in Armour Thyroid are levothyroxine and another thyroid hormone called liothyronine (T3). Armour Thyroid and levothyroxine
The thyroid normally produces T4 and T3. About 85% of the hormone that goes from the thyroid into the blood stream is T4 (thyroxine) and only 15% is T3. T3
(T3); liotrix, a synthetic combination of T4 and T3; and desiccated natural thyroid (natural thyroid hormone prepared from dried porcine [pig] thyroid).
T3-Max-25 is a synthetic thyroid hormone called liothyronine sodium. It is created on the basis of the thyroid hormone triiodothyronine (T3).
DRUG: T3, Tri-iodothyronine, is the most active thyroid hormone. USE: T3 is used to treat conditions of low thyroid.
T3-Max-25 is a synthetic thyroid hormone called liothyronine sodium. It is created on the basis of the thyroid hormone triiodothyronine (T3).
The thyroid gland makes two thyroid hormones: thyroxine (T4) and triiodothyronine (T3). Normally, the thyroid gland makes mainly T4 and only a small amount of T3. T4 is changed into T3 in other places in the body. In hyperthyroidism, the thyroid gland usually makes extra amounts of both T4 and T3 but in some cases it only makes too much T3.
T3 (usually as Free T3) and thyroid antibodies (if Thyroid-hormone replacement therapy and some drugs may interfere with thyroid
