Evidence Summary
Amongst its key roles, Selenium has been indicated to protect the thyroid gland from oxidative stress and is necessary for thyroid hormone production. Selenium plays a key role in the health of your immune system. This antioxidant helps lower oxidative stress in your body, which reduces inflammation and enhances immunity. Selenium is required to sustain proper health in both animals and humans due to its linkage with various biological functions in the immune system. Nature has made it impossible for us to obtain sufficient Selenium from the diet since some regions across the globe have been designated as Selenium deficient. Selenium deficiency is associated with a compromised immune system and increased susceptibility to various diseases. Numerous studies have shown a deficiency in Selenium appears to result in immunosuppression, whereas supplementation with low doses of Selenium appears to result in augmentation and/or restoration of immunologic functions (1). According to studies, consuming foods with selenium — such as Brazil nuts, eggs, liver, tuna, cod and sunflower seeds — and/or taking a daily selenium supplement can have positive antiviral effects, support fertility and reproduction, and may even reduce the risk of some types of cancer, autoimmune diseases and thyroid disorders.
