The thyroid is the small butterfly-shaped gland in your neck that can sometimes wreak havoc on your life. The thyroid is able to get away with sorts of mischief because the small gland wields mighty power when not in balance. Thyroid 5 provides thyroid support with sea plants rich in iodine. Why iodine?
