The thyroid is a small, butterfly-shaped gland located near the base of your neck that makes and stores thyroid hormones. Thyroid hormones play a big role in our bodies, as they help regulate energy levels, metabolism, body temperature, mood, heart rate, and blood pressure. Nutrients like Iodine, Zinc, and Selenium are very important for thyroid health and can be found fish, seaweed, dairy, and eggs, as well as legumes, nuts, and seeds.
