T3 thyroid hormone necklace | silver If you have spent enough time in an endocrinology clinic, you know the T3 conversation. The TSH is normal, the T4 is normal, the patient still feels off. The question is whether peripheral conversion to T3 is doing what it should. This 37 mm pendant in 925 sterling silver carries the molecule at the centre of it. The Science Behind T3 Triiodothyronine is the active form of thyroid hormone. It binds nuclear receptors and regulates the transcription of hundreds of genes that control metabolism, heart rate, body temperature, and developmental timing. The thyroid secretes only about 20 percent of circulating T3 directly. The rest is generated in peripheral tissues, particularly the liver and kidney, by deiodinase enzymes that remove a single iodine atom from T4. Genetic variants in the DIO2 gene have been associated with reduced peripheral conversion in some studies, and the question of whether T4 monotherapy is sufficient for every patient remains an active area of clinical research. Who Tends to Wear This The wearer is usually someone for whom T3 is not an abstract concept. endocrinologists and thyroidologists clinical researchers in deiodinase biology or combination therapy endocrinology fellows and physiology students patients who have argued for combination T3/T4 therapy and won Explore Related Molecules Jewelry T3 thyroid hormone necklace | gold vermeil T4 thyroid hormone necklace | silver T4 thyroid hormone necklace | gold vermeil T3-T4 earrings | silver T3-T4 ring | silver Frequently Asked Questions Why T3 specifically rather than T4? T3 is the active hormone. T4 is largely a circulating reservoir that becomes T3 only after a deiodinase removes one iodine atom. People who wear the T3 pendant tend to be those who think about thyroid hormone at the cellular level, where T3 binds and the genomic effects begin. Who is the typical recipient? Endocrinologists, thyroid researchers, and patients with personal thyroid history are the three groups that order this most. The piece tends to be chosen as a defended-PhD gift, a board-pass marker, or a personal milestone for a patient who has stabilised on T3 therapy.
