Selenium is an essential trace element required by the human body in small amounts. It operates as an antioxidant and in thyroid metabolism. It appears to have other important and positive roles in the body with some studies suggesting it may have anti-cancer properties when taken within safe dosage limits as discussed below.

Where do I get Selenium from?

Selenium is found in a variety of meat and vegetarian sources. The total amount of selenium in vegetarian products will depend heavily on the quantity of selenium in the soil in which the product grew.

As can be seen from the table to the right, Brazil Nuts are so high in Selenium that care is advised that people do not overindulge!

Other than nuts, quantities of Selenium are more modest but also spread across many different foods. Accordingly, people with a balanced diet are likely to get enough Selenium.

However, as discussed below, people who aren't able to maintain a diverse and balanced diet can consider a multivitamin containing Selenium to ensure they obtain enough of this mineral.

An easy way to ensure you get enough Selenium without resorting to supplements is to have a small handful of mixed nuts a day.
