Important Update on Selenium Supplementation


A while back I wrote an article on the role of selenium in autoimmune thyroid disease. I summarized several studies which found that selenium supplementation reduced inflammation and damage to thyroid tissue, lowered thyroid antibody levels in the blood, and improved the conversion of T4 to T3. However, I also sounded a note of caution when it comes to selenium supplementation: “These preliminary studies show the positive effects of selenium supplementation on inflammatory activity in… Read More
