Selenium is a trace element and a constituent of more than 20 selenoproteins that play critical roles in supporting reproduction, thyroid hormone metabolism, DNA synthesis and antioxidant status. Selenium exists in two forms: inorganic (selenate and selenite) and organic (selenomethionine and selenocysteine). Most selenium found in human and animal tissues is in the organic form of selenomethionine, where it can be incorporated with amino acids. Skeletal muscle is the major site of selenium storage.Selenium has structural roles, as well as enzymatic functions. It is best-known as an antioxidant and catalyst in the production of active thyroid hormone. Selenium is essential in the balance and support of immune system function. Selenium promotes sperm motility, supports positive mood, antioxidant status, inflammation balance, and heart health. In the context of potential health effects, low selenium status is cause for concern.Selenium provides 200 mcg per serving of selenium. Maintaining optimal selenium levels helps support a positive mood, improves antioxidant status, and promotes inflammatory balance and heart health.AV
