Fate of Iodine in Thyroid Hormone Formation - Why Iodine is Necessary For Thyroid Hormone Formation August 03, 2009 To form sufficient quantities of the thyroid hormone thyroxine or T4, about 50 milligrams of iodine in the form of iodides in the diet is required every year.

20. Ephedrine December 19, 2007 Ephedrine is a sympathomimetic drug and not a hormone compound. It offers athletes three distinct advantages in spite of not being a hormone compound. Ephedrine has clear fat burning characteristics. This occurs since Ephedrine produces heat in the body (thermogenesis). Simplified, Ephedrine slightly increases the body temperature so that the body burns more calories than usual. Ephedrine also stimulates the thyroid gland to transform the weaker LT-4 (L-thyroxine) into the stronger LT-3 (liothyronine), thus accelerating the metabolism. This fat burning effect, with the additional intake o... (read more) Author: mark henry
