Selenium is one of the most important micronutrients to include in a longevity minded health regimen and is frequently cited by antiaging specialists as an antioxidant that should be included on a life extension checklist.

In fact, selenium and Vitamin E, another powerful antioxidant, are synergists, meaning they each improve the efficiency of the other. Moreover, selenium is critical for the body to produce glutathione peroxidase, the body's master antioxidant.

What specific benefits are provided by selenium? According to Dr. Donald Lisk at Cornell University, selenium is a powerful "chemopreventive agent" which makes it a cancer fighter. Additionally, selenium intake can improve immune system strength, reduce the incidence of heart disease, keep blood vessels healthy, reduce the risk of stroke, potentially reduce anxiety and depression, and even increase fertility in men.

Selenium is an essential trace mineral that works closely with vitamin E to provide the body with powerful antioxidant protection from the free radicals that may contribute to the development of cancer, heart disease, and arthritis.

Selenium protects the body from free radical damage in two ways: It is incorporated into proteins to make selenoproteins, which are important antioxidant enzymes, and it helps the body manufacture itís own natural antioxidant, glutathione.

What are the potential benefits of taking Selenium?

Selenium may help fight cancer. In a study published in the Journal of the American Medical Association, selenium reduced colorectal, lung, and prostate cancer mortality in humans by 50 percent over 10 years.* Selenium may also prevent or slow tumor growth by boosting immune cell activity and suppressing development of blood vessels to the tumor.
