Selenium

Selenium is an essential trace mineral associated with supporting normal thyroid function, antioxidant enzyme activity, normal immune function, and male reproductive health. New Zealand and Australian soils are naturally lower in selenium — making dietary intake and supplementation more relevant in this region.


Selenium supports the activity of antioxidant enzymes including glutathione peroxidase and is associated with normal thyroid hormone metabolism. Selenomethionine is the most bioavailable supplemental form. Selenium has a narrow intake range — most supplements provide a range considered appropriate for addressing common dietary shortfalls. Do not exceed recommended doses.
