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. Since selenium can’t be manufactured by the human body, it has to be obtained from diet or supplements. Ultimate Selenium™ provides selenium, vitamins and other trace minerals and nutrients to support good health. For best results, use Ultimate Selenium™ as part of a full nutritional program that also includes the Healthy Body Start Pack.
