Selenium helps the immune system be less reactive in people who are already suffering from thyroid disease and is essential for clearing toxic chemicals from the thyroid cells. With well-balanced nutrition, you should be getting between 30 and 85 mcg of selenium daily, but Dr. Arem recommends you get at least 100 mcg to prevent thyroid cell damage and keep your immune system less reactive. Do not take supplemental selenium exceeding 300 mcg a day.
