Selenium TR

Selenium TR is a mineral found in soil and naturally present in some foods (like whole grains, Brazil nuts, sunflower seeds, and seafood). The body does not produce Selenium TR, but it is necessary for the proper functioning of the thyroid and the immune system.

Selenium TR is used to treat or prevent Selenium TR deficiency.

Selenium TR has been used in alternative medicine to help treat Hashimoto's thyroiditis (an autoimmune disorder of the thyroid) and to treat high cholesterol.

Not all uses of Selenium TR have been approved by the FDA. Selenium TR should not be used instead of medication prescribed by your doctor.
