Description
Selenium is a trace mineral essential for various bodily functions. It plays a crucial role in antioxidant defenses, helping to protect cells from damage. Selenium is also involved in the production of selenoproteins, which support immune system function and overall health. The human body requires selenium in small amounts, and it can be obtained through dietary sources or supplements. Selenium deficiency can lead to impaired immune function and increased susceptibility to infections. Selenium is also important for thyroid function and can help regulate metabolism. The mineral has been shown to have anti-inflammatory properties, which can help reduce oxidative stress. Selenium can be found in foods such as Brazil nuts, fish, and turkey, but supplements can help ensure adequate intake.
