Selenium: Overview
Selenium is an essential trace mineral present in almost every cell of the body. The highest concentrations of Selenium in the body are found in the kidneys, liver, pancreas, spleen and testes. Selenium can be obtained in the diet through seafood, poultry, meat, grains, brazil nuts and in supplement form.
Health Benefits
Selenium is very important for good health, and has many functions. Helping to boost the immune system, Selenium also has powerful antioxidant properties to help keep disease at bay. Studies show Selenium to have strong cancer-preventative properties, and to have anti-inflammatory activity. Additionally, Selenium may help prevent heart attack and stroke by making blood less likely to clot, and by increasing HDL (good) cholesterol levels.
Research shows that Selenium may be important in the prevention of age-related macular degeneration and the formation of cataracts. Selenium may also help suppress or shorten the duration of herpes outbreaks. Selenium may also help to enhance male fertility.
Using Selenium
Multi-vitamin supplements may or may not provide sufficient amounts of Selenium, so check the label. Consult your doctor before taking a Selenium supplement if you have a health condition or are taking any medication.
Take at least 400 IU of vitamin E with Selenium for maximum absorption.
