The Thyroid and Thyroid Hormones

The Thyroid and Thyroid Hormones

The thyroid is a small gland that lies in the neck about the level of the Adam’s apple and weighs approximately one ounce.  It produces thyroid hormone and calcitonin.  The parathyroid glands are very small and lie on the outside portion of the thyroid gland and secrete parathyroid hormone.  Thyroid hormone ignites your metabolism so you can burn fat and produce energy.  We will be focusing on thyroid hormone.

The thyroid gland is stimulated to make thyroid hormone by thyroid-stimulating hormone (TSH) which is produced in the pituitary gland located in the brain.  The pituitary is controlled by the hypothalamus in the brain which monitors the amount of circulating thyroid hormone.  Iodine must enter the thyroid gland through a transport system that is repaired with the intake of vitamin C.  There is usually about 20-30 mg of iodine in the body and 75 percent of it is stored in the thyroid.  In addition to iodine, iron, tyrosine, selenium, vitamin E, vitamin C, vitamin D, magnesium, zinc, copper, and vitamins B2, B3, and B6 are required for thyroid hormone production.

Testosterone

Testosterone is made in the testes and adrenal glands in a male, and in a woman, the ovaries and adrenal glands.  Testosterone is very important for metabolism.  It has been shown that low thyroid states result in low testosterone levels.  When the thyroid gland returns to optimal function in individuals with challenged thyroids, their testosterone levels also return to normal.  Testosterone replacement can help many conditions including thyroid and autoimmune diseases but simply giving these patients testosterone without correcting the reason why their testosterone is low in the first place does a great disservice to these patients in the long run.
