Colloidal silver

The use of colloidal silver is not approved while on the Marshall Protocol. Colloidal silver may interfere with the body's absorption of tetracyclines, and thus could affect absorption of minocycline. It also affects absorption of thyroxine & several other classes of drugs.¹⁾

While colloidal silver is marketed for internal and external use as an alternative medical remedy, and there is some in vitro evidence suggesting that it has antibiotic effects, there is currently no scientific evidence of its effectiveness in vivo.²⁾ In vivo antibiotic effectiveness could make colloidal silver dangerous in someone using the Marshall Protocol: it is not regulated as a pharmaceutical, and its effectiveness could therefore vary widely between batches, leading to unpredictable levels of immunopathology.

Although colloidal silver as a trace element, rather than as ABx may have some validity in a very small number of patients, an excess of silver may becomes dangerous.

Colloidal silver products can have serious side effects.³⁾ In rare cases of excessive long-term use, it use can result in argyria, a form of silver toxicity.^{4) 5)}
