Descriptions. Selenium supplements are used to prevent or treat selenium deficiency. The body needs selenium for normal growth and health. Selenium is needed for certain enzymes that help with normal body functions.Although selenium is being used to prevent certain types of cancer, there is not enough information to show that this is effective.f you think that you are not getting enough vitamins and/or minerals in your diet, you may choose to take a dietary supplement. Selenium is found in seafood, liver, lean red meat, and grains grown in soil that is rich in selenium.
Selenium occurs in minerals such as eucairite (CuAgSe), crooksite (CuThSe) and clausthalite (PbSe), but these minerals are too rare to use as a major source of selenium. Today, most selenium is obtained as a byproduct of refining copper. Selenium's resistance to the flow of electricity is greatly affected by the amount of light shining on it. The brighter the light, the better selenium conducts electricity. This property has made selenium useful in devices that respond to the intensity of light, such as electric eyes, photo cells, light meters for cameras and copiers. Selenium can also produce electricity directly from sunlight and is used in solar cells.
