Trace amounts of gold, about 0.2 milligrams, are naturally present in the human body, but the core question remains: does gold break down in the body when ingested or used in medical applications? The answer depends largely on its form, as pure, metallic gold behaves very differently from its ionic or nanoparticle counterparts.

Despite claims made by some dietary supplement companies, ingesting gold nanoparticles is not recommended and comes with potential health risks. The inert nature of bulk gold changes drastically at the nanoscale, where properties like large surface area and high reactivity can become toxic within the body. While some products containing colloidal gold are marketed for wellness, many expert bodies warn against their oral use due to insufficient safety data.

Did you know that standard ascorbic acid, a form of vitamin C, is highly unstable and can lose a significant portion of its potency when exposed to light and air? The development of gold complex vitamin C represents a technological leap, combining vitamin C with submicrometric gold particles to dramatically enhance its stability, absorption, and effectiveness, particularly for topical applications.
