Did you know that the thyroid gland has the highest concentration of selenium compared to any organ in your body? Selenium is a powerful and essential trace mineral actually first discovered by the Swedish chemist Berzelius in 1817. Selenium mainly acts as an antioxidant, anti-inflammatory, and it is involved in the production and activation of thyroid hormone.
Selenium protects the thyroid from oxidative damage but a deficiency can lead to an increase in the weight of your thyroid which can be compounded by an iodine deficiency. When you’re deficient in selenium, you actually lose iodine more quickly so these two substances must work in perfect balance.
