The function of the thyroid gland is to take iodine, found in many foods, and convert it into thyroid hormones: thyroxine (T4) and triiodothyronine (T3).Thyroid cells are the only cells in the body which can absorb iodine. These cells combine iodine and the amino acid tyrosine to make T3 and T4.he function of the thyroid gland is to take iodine, found in many foods, and convert it into thyroid hormones: thyroxine (T4) and triiodothyronine (T3).
The thyroid gland is an organ that produces hormones that regulate important bodily functions, including metabolism. The thyroid is stimulated to produce its hormones by another hormone called thyroid stimulating hormone, or TSH. When thyroid hormone levels are abnormally high, TSH is typically low. Low TSH can cause a host of symptoms, ranging from general symptoms to symptoms specific to a particular organ.
