Selenium Supplementation

Meaning

Selenium supplementation is the clinical or nutritional practice of ingesting controlled amounts of the essential trace mineral selenium, typically provided in an organic or inorganic salt form, to ensure adequate intake and support optimal physiological function. Selenium is indispensable for the proper activity of selenoproteins, which are critical components of the body’s antioxidant defense system, immune response, and the complex metabolism of thyroid hormones. Supplementation is often clinically guided by serum or whole-blood selenium status.
