What is Selenium? 

Selenium is a mineral found in the earth's soil. It is made of various enzymes and proteins which help to protect against cell damage (free radicals)and help fight infections. It can also help to make DNA. It is also a Glutathione cofactor and is needed for glutathione activity. Anyone who is monitoring their glutathione levels should also consider their selenium levels too.
