If you experience side effects at any point, such as nausea or skin discoloration, stop using colloidal silver immediately.
Colloidal silver products can vary widely in their composition, so their effects may also vary widely.
Colloidal silver is said to have broad antibacterial and antiseptic effects when taken orally or placed on a wound.
Colloidal silver’s most common commercial form is as a liquid tincture. Most health food stores carry it. It can also be bought as a powder to apply to your skin. Some people even make their own colloidal silver at home, using a special machine.
What’s more, if you use it frequently on an open wound, you may experience localized argyria due to a buildup of silver in the surrounding tissue (18).
Its advocates claim that it’s an effective treatment for all sorts of infections and diseases, ranging from the common cold to cancer.
If you decide you’d like to try colloidal silver, check to make sure that it won’t interact with any prescriptions you’re taking. Consider topical use with guidance from a healthcare professional. Never exceed the dosing recommendations put forward by the EPA.
The real risks of ingesting nanoparticles, which may be present in colloidal silver products, are also unknown.
Colloidal silver is a suspension of silver particles in a liquid. It’s an ancient remedy that was once used to treat bacterial, viral and fungal infections.
Companies that claim that colloidal silver is a miracle cure for diseases such as cancer and HIV are doing so without any clinical proof. There are many other safe options for staying healthy, preventing disease, and getting better from illness.
Applying colloidal silver to your skin is considered less risky than ingesting it. However, if the solution contains very small nanoparticles, you may absorb these through your skin (17).
Before modern antibiotics were developed, colloidal silver was used as an all-purpose remedy for various infections and illnesses.
Silver isn’t a vitamin or mineral that naturally occurs in the body. You don’t need to make sure you’re getting an adequate dose of silver or do anything to make up for not being exposed to it.
Considering the risks and lack of proven benefits, using colloidal silver products is probably not a good idea.
Recently, it has experienced a revival in popularity, with some claiming it can replace antibiotics or other medical therapies to treat bacterial, viral and fungal infections.
Colloidal silver is a classic example of anecdotal reports that differ drastically from scientific research. Always remember that oral colloidal silver isn’t a product that’s regulated by the FDA.
However, given that these particles may more easily pass into your cells and possibly cross the blood-brain barrier, they are considered a probable health risk (6).
A smaller number of people also claim it can help treat illnesses such as Lyme disease, tuberculosis and even HIV/AIDs.
A dosing reference chart created by the EPA suggests that your daily silver exposure — topical, oral, or environmental — shouldn’t exceed 5 micrograms per every kilogram you weigh.
Ingesting colloidal silver puts you at risk of developing a condition called argyria. Ingesting silver nanoparticles, which may be present in colloidal silver solutions, is also considered to be risky.
The size of the silver particles in colloidal silver can vary, but some are so tiny that they are referred to as “nanoparticles.” This means that they are less than 100 nm in size and invisible to the naked eye (1).
