    Selenium (/sɨˈliːniəm/ si-lee-nee-əm) is a chemical element with the atomic number 34, represented by the chemical symbol Se, which has an atomic mass of 78.96. It is a nonmetal, whose properties are intermediate between those of sulfur and tellurium. It rarely occurs in its elemental state in nature, but instead is obtained as a side-product in the refining of other elements.http://en.wikipedia.org/wiki/Selenium

    Researchers writing in the July 15, 2000 issue of the British-based international medical journal, The Lancet, called attention to the importance of selenium to health, citing the trace mineral's potential to reduce the risk of thyroid problems, pregnancy and fertility problems, heart disease, and progression of HIV to AIDS, among other important findings.
