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.
Pro-Balance Selenium provides 200 mcg per serving of selenium, ideally formulated using the amino acid chelate form of selenium (selenium glycinate) for enhanced absorption, optimal utilization and gastrointestinal comfort. Maintaining optimal selenium levels helps support a positive mood, improves antioxidant status, and promotes inflammatory balance and heart health.
The importance of bioavailability is obvious. If consuming a selenium supplement has little effect on improving the body’s selenium balance, there is no reason to ingest it. Signs of inferior mineral supplements include the use of cheap, poorly absorbed, rock-salt minerals. Reacted Selenium, formulated in the superior amino acid chelate form, selenium glycinate complex, has a high level of stability, which helps it to avoid food and other minerals that compete for absorption in the gut. This stability allows for enhanced absorption in the gastrointestinal system.
Selenoproteins play a role in supporting oxidative modification of lipids, inflammation balance and healthy blood flow. For these reasons, experts have suggested that selenium supplements could impact heart health. In addition, selenium plays a role in cognitive health. Serum selenium concentrations decline with age. Sufficient selenium concentrations might play a role in supporting brain function throughout the lifespan, possibly due to selenium’s antioxidant activity. Selenium concentration is higher in the thyroid gland than in any other organ in the body. Selenium, like iodine, has a significant supporting role in thyroid hormone synthesis and metabolism.
