Selenium is a trace mineral important for thyroid hormone metabolism (it's needed for enzymes that activate and regulate thyroid hormone) and for antioxidant defense, through its role in glutathione peroxidase, one of your body's key antioxidant enzymes. Deficiency is uncommon with a typical varied diet but can occur with very restrictive diets, certain malabsorption conditions, or in regions with selenium-poor soil, and can affect thyroid function and immune health. Excess selenium, most often from over-supplementation, can also cause toxicity, so testing is used to evaluate either possibility when clinically relevant.

Selenium is crucial for our body, acting as a building block for important proteins called selenoproteins. These proteins, including powerful antioxidants like glutathione peroxidase, protect our cells from damage by removing harmful substances produced by our body. Without selenium, our cells could be damaged, leading to problems with blood clotting and cell membrane integrity by affecting substances that control blood clotting.

This test measures the level of selenium in whole blood. Selenium is a vital antioxidant mineral involved in thyroid function, immune response, and protection against oxidative stress.
Most people know vitamins are important — but few realize that minerals are the “spark plugs” of your cells. They activate the enzymes that drive nearly every process in your body, from hormone production to detoxification to energy creation. Without enough minerals, even the healthiest diet and lifestyle can fall short, leaving you feeling fatigued,…
