Many people use colloidal silver as a general health supplement, as well as for the treatment of various ailments. For example, people may use colloidal silver to combat infections, to treat Lyme disease or just to improve their general health. However, because of the potential for side effects when taking colloidal silver, its use has been controversial in some circles.

Below is some information about colloidal silver, its benefits and its risks.

Potential Benefits of Taking Colloidal Silver

Throughout history, colloidal silver has been used for a wide variety of purposes. Today, it is used even more widely. While some of colloidal silver’s potential benefits are supported by the results of scientific research, others are not.

Some of the potential benefits of taking colloidal silver supplements include:

  • Preventing infections – Some studies indicate that colloidal silver can kill various pathogens, including fungi, viruses and bacteria. For this reason, some people may take colloidal silver in hopes of preventing fungal, viral or bacterial infections.
  • Treating infections – Historically, colloidal silver has been used to treat active infections. Its use for this purpose was particularly widespread prior to the development of antibiotics. Today, many people still use colloidal silver as an alternative method of treating infections.
  • Supporting the immune system – Some people consume colloidal silver every day as a supplement in hopes of supporting and improving the function of the immune system.
  • Treatment of other ailments – Many people believe that colloidal silver can be taken to treat ailments other than infections. Research results with regard to other potential uses of colloidal silver have been mixed.

Risks of Taking Colloidal Silver

When taking any supplement, it is important to weigh the potential desired benefits against any associated risks. Research studies have identified several risks that may be associated with taking colloidal silver. These risks are more substantial when you choose to take uncoated colloidal silver. Risks are present whether you take colloidal silver orally or apply it to your skin. Risks are greater with everyday usage than occasional usage.


Argyria is a rare but serious side effect that can occur among people who take colloidal silver in large dosages or for an extended period of time. The risk of argyria may also be higher when poor quality supplements are used.

Argyria occurs when silver particles build up in the body’s tissues, including the skin and mucous membranes. Over time, this can cause the tissues to look blue or grayish in color. The color change itself is not dangerous to your health, but it can be embarrassing. In addition, the buildup of silver particles in the skin indicates that these same particles are likely building up in other parts of the body as well, where they may be able to cause more substantial damage. In many cases, argyria will not be reversible.

Organ Damage

Some studies have indicated that colloidal silver may pose more serious risks to certain organs, including the liver and kidneys. The likelihood of damage to these organs increases when colloidal silver is used for an extended period of time.

Drug Interference

Taking colloidal silver may alter the concentration and/or effectiveness of other medications, as colloidal silver changes the way your body absorbs these medications. Examples of medications that may be impacted by taking colloidal silver include antibiotics and thyroid medicine.

Other Side Effects

Other possible side effects of colloidal silver supplements include:

  • Neurological issues
  • Headaches
  • Stomach/digestive problems
  • Silver allergy (very rare)


Taking Colloidal Silver Safely: Maximizing Benefits and Minimizing Risks

The possible side effects of colloidal silver consumption are most often related to the buildup of silver in the body. Thus, you can greatly reduce the risk of these side effects by choosing a colloidal silver supplement that is less likely to accumulate in your organs and other tissues.

One of the best ways to prevent the buildup of silver in your body is to choose a coated colloidal silver supplement. Coated colloidal silver supplements differ from uncoated supplements in that each silver nanoparticle in a coated supplement has a protective coating designed to improve your body’s ability to process the supplement. This coating ensures that the silver nanoparticles maintain a uniform size and shape, and it prevents them from sticking together and forming clumps. This means that the body will be able to process the supplement easily and no dangerous buildup of silver particles will occur. In addition, coated colloidal silver is a slow-releasing particle that can effectively permeate the spaces between the cells. It also contains a neutral charge, which means it won’t produce uncontrolled reactions that could pose a danger to your health.

When taking colloidal silver for any purpose or condition, it is also important to take the appropriate dosage. Colloidal silver supplements include different concentrations of ions, so check your product’s label to determine how much you should take. You should also follow the instructions provided by the product’s manufacturer. If you notice worrisome side effects, discontinue your use of the supplement and report the problem to your doctor.
