What is Selenium? Selenium is a trace mineral that is essential for antioxidant support within the body. Research shows that many people with certain conditions are highly at risk of being deficient in this certain mineral. A diet with high-quality sources of meat and fish is the best way to support mineral balance in the body. A selenium supplement can also add valuable support, but should only be taken with the guidance of your healthcare professional.
