Sulfur is widely distributed in nature. It is found in many minerals and ores, e.g., iron pyrites, galena, cinnabar, zinc blende, gypsum, barite, and epsom salts and in mineral springs and other waters. The metabolism of sulfur amino acids, methionine and cysteine, has been linked to several key aspects of human health and cellular function.
