Selenium (Se) is an element that we get from food, and it is also an antioxidant. Selenium is present in the muscles, liver, kidneys, thyroid gland, platelets, and heart. Selenium contributes to the well-being of hair and nails, normal thyroid function, the production of sperm, and the function of the immune system. Selenium deficiency can also cause damage to the heart muscle.
Selenium is absorbed into the body from the gastrointestinal tract. Excess selenium is excreted into urine. Fish and shellfish contain a lot of selenium, but we also get it from grains, dairy products, and meat.
When should selenium be measured?
The level of selenium is usually measured when examining possible selenium deficiency. Other trace elements, such as copper and zinc, are also often tested together with selenium.

What can cause elevated selenium values?
High selenium levels indicate that the body has received too much selenium from food and/or nutritional supplements. This is known as selenium toxicity. In the worst case, it can cause damage to the liver and nervous symptoms.
What can cause decreased selenium values?
Low selenium levels suggest selenium deficiency in the body, which can involve depression and anxiety. A link has also been suggested to an increased risk of cardiac diseases and malignant tumours.
