Selenium may be a trace mineral, but its importance for human health is anything but small. Often overshadowed by more popular nutrients like zinc or magnesium, selenium plays a critical role in thyroid function, antioxidant defense, immune response, and even fertility. It’s one of the body’s most powerful natural defenders against cellular damage and inflammation.
Found naturally in soil, selenium enters the food chain through plants and animals. While it’s needed only in microgram amounts, a deficiency or imbalance can lead to fatigue, thyroid dysfunction, or weakened immunity. In this article, we’ll explore the many ways selenium supports your health and how to ensure you’re getting enough through diet or supplements.
