Germanium comes from inside the earth’s crust, but is also present in living matter and the human body. Plant foods, such as wheat, vegetables, bran and leguminous seeds, are rich sources of germanium. Pure GeOxy-132 Organic Germanium is a unique organic germanium compound, bis-carboxyethyl germanium sesquioxide, sometimes called just “germanium sesquioxide.” The high-purity organic complex is safe, with much lower toxicity than the inorganic form; germanium dioxide is a form of inorganic germanium.
