Description

Propagermanium, also known as 2-carboxyethylgermanium sesquioxide, is an organogermanium compound that has been marketed as a dietary supplement. It is believed to possess antioxidant properties and is claimed to have various health benefits, including boosting the immune system, improving blood circulation, and inhibiting cancer cell growth. However, scientific evidence supporting these claims is limited and inconclusive. Propagermanium is synthesized by reacting germanium dioxide with 2-chloroethyl carboxylate in the presence of a catalyst. The compound is relatively stable and can be administered orally or intravenously. Its potential benefits are attributed to its ability to enhance the activity of certain enzymes and to stimulate the production of interferon, a protein that plays a role in the immune response. Despite its popularity as a dietary supplement, propagermanium is not approved for medical use in most countries. More research is needed to fully understand its safety and efficacy.'
