Webb22 mars 2024 · Armour Thyroid is a tablet that contains both T3 and T4, which are the two main thyroid hormones that are naturally produced in the body. T3 has more than four times the level of activity in the body as T4, and the body uses T4 to make T3. Although the body produces about 15 times as much T4 as it does T3, some people have a difficult … Webb10 feb. 2024 · The primary active compound is T 3 (triiodothyronine), which may be converted from T 4 (thyroxine) and then circulates throughout the body to influence …
Webb19 sep. 2015 · 2. Mode Of Action Of Thyroid Hormones Thyroid hormone acts on target cells (particularly cells of liver, muscle and kidney), most of the T4 is deiodinated to form T3. True intracellular hormone is T3, rather than T4. Moreover, T3 is found freely in the plasma and T4 is usually bound with plasma proteins. So, at the site of action, T3 acts … WebbThe thyroid hormone receptors belong to a nuclear receptor superfamily that also includes receptors for other small lipophilic hormones.
