What is t3 made from?

T3, or triiodothyronine, is a thyroid hormone that is produced by the thyroid gland from the conversion of T4 (thyroxine) with the help of enzymes. It plays a role in regulating metabolism and other bodily functions.


What is T3 and T4 and T1 and T2?

T3 and T4 are hormones produced by the thyroid gland that regulate metabolism. T3 is triiodothyronine, and T4 is thyroxine. T1 and T2 are not commonly used medical terms in the context of thyroid hormones.


Are T3 and T4 amines?

Is the t4 or t3 active in this particular supplement?

The supplement contains active T3.


How are T3 T4 and TSH related?

TSH is the hormone produced by the pituitary gland that tells the thyroid to produce the thyroid hormones T4 and T3.

How is t3 and t4 synthesized in the thyroid gland?

T3 (triiodothyronine) and T4 (thyroxine) are synthesized in the thyroid gland through a process that begins with the uptake of iodine from the bloodstream. Iodine is incorporated into the amino acid tyrosine within the protein thyroglobulin, forming monoiodotyrosine (MIT) and diiodotyrosine (DIT). These iodinated tyrosines are then coupled to produce T3 and T4. Finally, T4 is released into the bloodstream, while a smaller amount of T3 is also secreted, with T4 being converted to T3 in peripheral tissues as needed.


Why are they reluctant to do the thyroid T4 test?

The old Total T4 test (TT4) is no longer considered the best way to test for T4 levels. T4 and T3 can both be bound by other proteins and hormones in the body. When this happens, the T4 or T3 is not usable by the body. The body can only use T4 and T3 that is not bound, or free. For this reason, Free T4, which only tests the free levels of the hormone, is now preferred over Total T4 testing as more accurate.


What does thyroid secret?

The thyroid secretes two main thyroid hormones. One of these hormones is called 'T4' or 'thyroxine' and the other is called 'T3' or triiodothyronine. The gland secretes roughly 80% T4 and 20% T3. There are very tiny amounts of other thyroid hormones known as T2 and T1 but they don't appear to be clinically very important as the vast majority of hypothyroid patients do well on T4 supplementation alone and nearly all those who are still dissatisfied feel well again once T3 is added as well.All of the T4 produced by the thyroid undergoes peripheral deiodination in the liver to become T3 as T3 is the metabolically active thyroid horome.
