Pure Ge-132 Germanium is a unique organogermanium compound, bis-carboxyethyl germanium sesquioxide, sometimes called just germanium sesquioxide. It has unique molecular characteristics which make it non-toxic and permit it to be readily cleared in the urine as the intact molecule.*

Allergy Research Group® introduced pure germanium into the United States in 1986. We recognize the importance of providing pure and tested Ge-132. To assure the quality and purity of our germanium products, we carefully analyze every lot. Testing procedures include identification by infrared spectroscopy, purity by acid group titration, and absence of inorganic germanium impurities by color limit test.
