What is Synthroid®?
Synthroid® is a synthetic form of the thyroid hormone, thyroxine. The primary function of this hormone is to regulate the metabolic rate of the cells found in virtually every tissue in the human body. This hormone is also responsible for regulating body temperature and plays a role in cognitive functioning and in the digestion of food. For people with low thyroid hormone levels, these processes become impaired, leading to a condition known as hypothyroidism, or low thyroid. Synthroid® has been a standard hypothyroidism treatment since the mid-1950s.
