The thyroid gland is located on the front part of the neck below the thyroid cartilage (Adam's apple). Introduction Thyroid hormones used therapeutically include crude thyroid extracts as well as synthetic forms of L-thyroxine (levothyroxine, T4) and L-triiodothyronine (liothyronine, T3). In fact, it is estimated that 1 in 7 Americans suffer from a thyroid disorder, yet nearly 60 percent of those individuals are completely unaware of their condition.

When you combine hypothyroidism with the common low-thyroid symptom of brain fog, maybe even a bit of depression, and you’ve got a Thyroid Stimulating Hormone (TSH) Suppression. When T3 and T4 levels are low, the body produces more TSH to stimulate the thyroid. The two thyroid hormones, thyroxine (3,5,3′,5′-tetraiodothyronine) and 3,5,3′-triiodothyronine, are formed by the addition of iodine to an amino acid (tyrosine) component of a glycoprotein called thyroglobulin.

THYROID HORMONE:• Gross and Microscopic Anatomy of the Thyroid Gland.
