Over the last few decades, there have been several reported problems associated with silver ingestion, including intestinal ulcers and argyria. With the availability of more effective pharmacologic alternatives, physician-directed use of silver-containing products has significantly declined. However, recently many health-food manufacturers have promoted colloidal-silver-based products as cure-alls. With the proliferation of the Internet, it has become much easier for these manufacturers to market their products to unsuspecting consumers using unsubstantiated claims of effectiveness against major illnesses such as AIDS, cancer, arthritis, and infectious diseases.
A negative association made to silver supplementation is the condition Argyria, an extremely rare phenomenon where silver accumulates in the tissue under the skin causing a blue or grayish tint.
