What Is Selenium?

Selenium is an essential trace mineral that your body needs in small amounts to function properly. Even though it is required in tiny quantities, it plays a powerful role in maintaining overall health. Many people search for selenium benefits because this nutrient is directly linked to immunity, metabolism, and cellular protection.

Unlike vitamins that your body cannot produce, selenium must be obtained through diet or supplements. It is naturally found in soil, which means the amount in food depends on where it is grown. This makes understanding selenium-rich foods especially important for maintaining balanced nutrition.
