What is the thyroid gland?
The thyroid gland is a small, butterfly-shaped organ found at the lower middle part of the neck. It is sometimes referred to as the “master controller” of metabolism, and is important to health and well-being. The thyroid creates, stores, and releases thyroid hormones into the blood. Thyroid hormones are important to the normal function of our body, and affect everything from the brain to our other organs.1
