Role of Selenium in Good Nutrition

Selenium is a powerful antioxidant. It works synergistically with vitamin E, meaning that both are more powerful when they are taken together.

Key Functions

  • Selenium helps to activate antioxidant enzymes such as glutathione peroxidase, which neutralizes potentially harmful free radicals.
  • Selenium is needed for healthy muscles, including the heart.
  • Selenium also plays a role in maintaining healthy eyesight, skin and hair.

Food Sources

Seafood, meats and grains

  • The actual content of selenium in whole grains depends on how much selenium is in the soil where the grains were grown.


Check with your local market for the recommended daily intake of selenium.

Safety Evidence

Elderly people, smokers, vegetarians and vegans, and pregnant or lactating women may need slightly higher amounts of selenium.
