The human body needs trace amounts of selenium to perform a variety of functions, including synthesizing antioxidants shown to protect against cell-damaging free radicals. And because selenium can’t be manufactured by the human body, it has to be obtained through diet or supplements. Ultimate Selenium is an all-in-one solution, providing selenium and other trace minerals, vitamins, and nutrients known to support overall health. For best results, use Ultimate Selenium as part of a full nutritional program that includes the Healthy Body Start Pak 2.0 & Plant Derived Minerals.
