Selenium toxicity was first confirmed in 1933 to occur in livestock that consumed plants of
the genus Astragalus, Xylorrhiza, Oonopsis, and Stanleya in the western regions of the …

Selenium is a fascinating element that has a long history, most of which documents it as a
deleterious element to health. In more recent years, selenium has been found to be an …

The biological activity of selenium is dependent upon its speciation. We aim to integrate
selenium speciation and metabolism into a discussion of the mechanisms by which …

Inorganic selenium and oxo-sulfur compounds are widely available in dietary supplements
