About this ingredient
Selenium is an essential trace mineral required for several important functions in the body. It forms part of selenoproteins and enzymes involved in antioxidant protection, thyroid hormone metabolism, immune function, and cellular processes. Selenium is naturally found in foods such as seafood, meat, eggs, dairy products, grains, and Brazil nuts, while supplements may contain forms such as selenomethionine or sodium selenite. Because the body requires only small amounts, excessive intake can cause adverse effects.
