Selenium is an essential trace mineral, and the body only requires small amounts to function properly. It works as an antioxidant, especially when it is combined with vitamin E. Antioxidants like selenium help in the fight against damaging particles in the body known as ‘harmful’ free radicals. It is essential for the good health of human beings.
Most of the selenium in the body comes from the diet. The amount of selenium that is actually present in food depends on where it is grown or raised. Brazil nuts, Crab, liver, fish, poultry, and wheat are generally all good sources of selenium.
