We came across posts on X claiming that colloidal silver can boost one’s immune system, and prevent viral and bacterial infections. Some of these posts included links to purchase colloidal silver supplements for consumption, while others even provided guides on how to make colloidal silver at home through electrolysis.
What is colloidal silver?
Colloidal silver is a solution containing tiny silver particles suspended in a liquid base. The silver used in these supplements is the same type used in jewellery and silverware.
Colloidal silver is available both as an oral supplement and for topical application. It is often sold in spray or liquid form, with labels such as “colloidal silver spray” or “silver hydrosol,” among other names. Many of these products are marketed with claims of boosting the immune system, fighting infections, and promoting overall health.

The rise of modern antibiotics
Historically, silver was used as a treatment for infections because of its antimicrobial properties. It was also considered a natural remedy for fungal infections and was thought to prevent viral ailments such as shingles and the flu.
Despite being eventually replaced by modern antibiotics for internal use in the early 20th century – which proved more effective in treating a wide range of health conditions – silver continues to be used in certain applications today. For instance, some wound dressings and bandages contain silver, as it might help kill harmful microbes when applied to the skin, helping to reduce the risk of infection in wounds.
However, concerns about the overuse of antibiotics have grown, particularly regarding the emergence of “superbugs” that exhibit high resistance to antimicrobial treatments. Additionally, misuse of antibiotics for minor or non-serious ailments may damage the immune system. These concerns may have led some people to seek out natural alternatives to antibiotics, looking for ways to support their health without relying solely on pharmaceutical solutions.
Can colloidal silver bolster our immune system?
While colloidal silver may offer some benefits when used topically, there is no evidence to support its efficacy in treating any diseases or conditions when taken as a dietary supplement. Silver is not an essential mineral and does not provide any health benefits when consumed orally.
In 1999, the U.S. Food and Drug Administration (FDA) determined that “over-the-counter drug products containing colloidal silver ingredients or silver salts are not generally recognised as safe and effective”. This decision followed an assessment by the FDA, which found insufficient evidence to support the claims made by manufacturers regarding the safety and efficacy of colloidal silver for treating medical conditions.
However, dietary supplements containing colloidal silver remain available for purchase on the market. Ingesting colloidal silver could interfere with certain medications, including other antibiotics and thyroid medications, and it poses serious health risks, such as kidney damage and seizures.
Turning blue from colloidal silver use
Additionally, prolonged consumption of colloidal silver can lead to a buildup of silver particles in the body and skin, resulting in a condition called argyria. This condition can cause a permanent blue-gray tint to the skin, eyes, organs, nails, and gums, although the exact amounts of consumption and the timeframe for its development are not well known.
A notable case is that of Paul Karason, who appeared on the Today Show in the US in 2008 to showcase his blue skin, a result of over 10 years of consuming colloidal silver. He later passed away in 2013 while being treated for pneumonia although argyria is not believed to have caused his death, as it is primarily a cosmetic issue and not thought to be inherently harmful.
There is no scientific research or human data to support the use of oral colloidal silver for the prevention, treatment, or cure of any health condition, nor is there evidence to support claims that it boosts the immune system. Furthermore, attempting to create colloidal silver supplements at home can be dangerous due to the risk of improper dosing and lack of quality control, which can increase the risk of argyria and other potential side effects.
Therefore, the claim that colloidal silver boosts our immune system is likely false. Consumers should exercise caution and consult healthcare professionals before using supplements, as the risks may outweigh any perceived benefits.
