Metabolite Identification
Common NameGermanium
DescriptionGermanium is not an essential element. Physiologically, it exists as an ion in the body. Its acute toxicity is low. Germanium-containing dietary supplements became popular in the 1970s in Japan and later in other countries, as elixirs for certain diseases (e.g., cancer and AIDS). However, at least 31 reported human cases linked prolonged intake of germanium products with renal failure and even death.
