Selenium

Discover why selenium is an essential trace mineral and why it plays an important role in antioxidant protection, thyroid function and immune health.

Selenium is an essential trace mineral that the body needs in small amounts to support many important biological processes. Although only tiny quantities are required, selenium contributes to normal immune function, thyroid function and the protection of cells from oxidative stress.

It is naturally found in a variety of foods, including Brazil nuts, seafood, meat, eggs and whole grains. In nutritional supplements, selenium is commonly provided in carefully measured amounts to help support an adequate dietary intake.

The Basics

Understanding Selenium

What is Selenium?

Selenium is an essential mineral, meaning the body cannot produce it on its own and it must be obtained from the diet. It forms part of a number of specialised proteins called selenoproteins, which are involved in many important biological functions.

Selenium Forms

Selenium supplements are available in several forms, including selenomethionine, selenium yeast and sodium selenite. Selenomethionine is one of the most commonly used forms because it is naturally incorporated into amino acids and is well absorbed by the body.

Antioxidant & Thyroid Support

Selenium contributes to the normal function of antioxidant enzymes that help protect cells from oxidative stress. It also contributes to normal thyroid function, as selenium-dependent enzymes help regulate thyroid hormone metabolism.

Frequently Asked Questions

What is selenium?

Selenium is an essential trace mineral required for many important functions in the body, including normal immune function, thyroid function and antioxidant defence.

What foods naturally contain selenium?

Selenium is naturally found in Brazil nuts, seafood, meat, poultry, eggs, dairy products and whole grains. The amount present in plant foods can vary depending on the selenium content of the soil in which they are grown.

Why are Brazil nuts known for selenium?

Brazil nuts are one of the richest natural food sources of selenium. However, the amount of selenium they contain can vary considerably depending on where they are grown.

Why is selenium important for the thyroid?

The thyroid gland contains one of the highest concentrations of selenium in the body. Selenium contributes to normal thyroid function by supporting enzymes involved in the production and metabolism of thyroid hormones.
