The thyroid is a butterfly-shaped gland in the neck of a person that controls the synthesis, secretion, and storage of thyroid hormones. The four major functions of thyroid hormones are: controlling the rate of energy use by the body, promoting the breakdown of proteins, fats and carbohydrates, promoting growth and regulating the body's sensitivity to other hormones, and being one of the most important glands in the body.

The thyroid gland is the endocrine organ with the highest selenium content in normal human bodies. It contains a variety of selenoproteins. It not only participates in the synthesis, activation and metabolism of thyroid hormones, but also plays an important role in the thyroid antioxidant system and immune system. Studies have confirmed that selenium deficiency is closely related to goiter, autoimmune thyroid disease, and thyroid cancer.
