What Is Selenium?

Selenium is an essential trace mineral that contributes to the normal function of the immune system, normal thyroid function, and the protection of cells from oxidative stress. It plays an important role in numerous biological processes and is a key component of antioxidant enzymes that help protect the body's cells from oxidative damage.

Benefits of Selenium

Supports the Immune System

Selenium contributes to the normal function of the immune system and helps protect cells from oxidative stress by supporting the body's natural antioxidant defence mechanisms.

Contributes to Normal Thyroid Function

Selenium plays an essential role in the metabolism of thyroid hormones and contributes to the normal function of the thyroid gland.

Provides Antioxidant Protection

Selenium is a component of antioxidant enzymes such as glutathione peroxidase, which help protect cells from oxidative stress caused by free radicals.

Supports Cardiovascular Health

By helping to protect cells from oxidative stress, selenium contributes to overall cellular health. A balanced diet that includes adequate selenium intake supports general cardiovascular wellbeing as part of a healthy lifestyle.

Contributes to Reproductive Health

Selenium contributes to normal spermatogenesis, an EFSA-authorised health claim relating to male reproductive health.

Note: There are currently no EFSA-authorised health claims stating that selenium supports female reproductive function. Therefore, no such claim should be made.
