Selenium is a rare mineral found in the soil, water, and some foods. The selenium content in plants its related to the selenium content of soil in which the plants grow.  While you only need a very small amount of selenium, it plays a key role in your metabolism. It’s necessary for cellular functions in many organisms, including all animals.

In the U.S., selenium deficiencies are uncommon. Some health conditions—such as HIV, Crohn’s disease, and others—are associated with low selenium levels.

Selenium can be found in fish, grass-fed and pasture-raised meats, whole grains, and nuts and seeds.

Is your intake of selenium adequate?

Remember that selenium salts are toxic in large amounts, and an overdose of selenium may cause:

  • Bad breath
  • Fever
  • Nausea
  • Liver, kidney, and heart problems
  • At high enough levels, selenium can cause death
