The thyroid hormone is actually present in two forms called T3 and T4. T4 is the macro-molecule and by the time it reaches its target tissue is hydrolyzed into T3. T3 is more than 100 times more active in metabolism than T4.

The hormone that requires selenium for its synthesis is thyroid hormone, specifically thyroxine (T4). Selenium is a crucial component of the enzyme deiodinase, which converts T4 to the more active form, triiodothyronine (T3). Adequate selenium levels are essential for optimal thyroid function and metabolism. Thus, selenium plays a vital role in regulating thyroid hormones.
