Colloidal silver
Colloidal suspension of silver nanoparticles marketed for antimicrobial, immune-boosting, and anti-aging effects. FDA ruled in 1999 that colloidal silver is NOT generally recognised as safe (GRAS) for any condition. EFSA and TGA concur. Causes argyria (irreversible blue-grey skin discolouration). No legitimate supplement use.
How it works (mechanism of action)
Acts on cellular signalling pathways relevant to the documented clinical indications. Contains bioactive compounds with enzyme-modulating, receptor-binding, or antioxidant properties studied in peer-reviewed literature.
FDA 1999 FINAL RULE: colloidal silver products are NOT safe or effective for any condition claimed. ARGYRIA: Irreversible permanent blue-grey/slate discolouration of skin, mucous membranes, and organs due to silver accumulation — no treatment exists. Neurological toxicity. Antibiotic interference (reduces absorption of antibiotics). Drug interactions: tetracyclines, quinolone antibiotics, penicillamine, thyroxine. Banned/restricted as supplement in USA, EU, Australia, Canada.
