Colloidal silver is an alternative therapy that may be used for a wide range of purposes, from treating deadly viruses to preventing bacterial infection. However, experts disagree about the safety of colloidal silver. While some say it can be used responsibly without significant risk, others maintain that colloidal silver can cause serious side effects.

What Is Colloidal Silver?

Colloidal silver is a solution of small particles of silver suspended in liquid. The size of the suspended particles varies, with some being too small to see without magnification.

Historically, colloidal silver was used to treat a variety of infections and illnesses, including bacterial infections. However, with the invention of modern medicines, colloidal silver was used less frequently. Recently, as more people have become interested in more natural alternatives to modern medicine, colloidal silver has seen a resurgence in popularity.

Colloidal silver may be taken orally as a dietary supplement, or it may be applied directly to the skin. Various strengths are available to meet different needs.

Why Is Colloidal Silver Used?

Colloidal silver may be used for many different medical purposes. For instance, some people claim it can treat fungal, viral and bacterial infections. Other people may use colloidal silver to address serious illnesses like HIV, tuberculosis or Lyme disease.

Researchers are not sure exactly how colloidal silver works. When used as an antiseptic or antibacterial, it may work by attaching to the cell walls of the bacterium or other pathogens and damaging their membranes. Damaged membranes allow silver to flow into the cell, where it can damage the cell DNA and cause death.

Potential Health Benefits of Colloidal Silver

The potential health benefits of colloidal silver vary widely. While some of these benefits are supported by research, others are not. Some of the potential health benefits of colloidal silver include:

  • Antifungal – Lab studies have indicated that colloidal silver can kill certain strains of fungi in a controlled environment.
  • Antiviral – Some people believe that colloidal silver can kill viruses and prevent or treat infections when ingested.
  • Antibacterial – Studies have shown that colloidal silver can kill many different types of bacteria. Prior to the invention of antibiotics like tetracycline, colloidal silver was commonly used in the treatment of bacterial infections.
  • Immune support – Some people believe that colloidal silver can boost immune system function when taken as a dietary supplement.

Is Colloidal Silver Healthy or Dangerous?

Because of the potential health benefits associated with colloidal silver, many people are curious about whether this substance can be used safely. Like any supplement, colloidal silver is not without risks. Before choosing to consume colloidal silver, it is important to understand these risks and weigh them against the potential benefits. If you choose to add colloidal silver to your daily regimen, it is also important to choose the safest and most reliable delivery system available.

Side Effects and Complications of Colloidal Silver

The use of colloidal silver has been linked to a number of possible side effects, making it necessary for users of this substance to exercise caution.

One of the biggest risks associated with the ingestion of silver nanoparticles is a condition known as “argyria.” Although this side effect is rare, it is worth considering before beginning a colloidal silver regimen. When someone develops this complication, their skin will begin to turn a bluish-gray color. This occurs because of a buildup of silver particles within the skin. Particles may build up in other parts of the body as well, including the internal organs.

For most people, argyria will only occur after ingesting silver nanoparticles for an extended period of time. It may also occur in individuals who are exposed to large amounts of silver because of work or another environmental issue.

Colloidal silver can also pose a risk for people who take certain medications. Specifically, colloidal silver can interfere with the absorption of medications into the bloodstream. Tetracyclines and quinolones tend to be absorbed less effectively when someone is also consuming colloidal silver. Colloidal silver may also interfere with the body’s ability to absorb thyroxine, a thyroid medication.

The Mayo Clinic reports that excessive use of silver is associated with other potentially-serious side effects as well, including neurological issues and seizures.

In general, the risk of side effects and complications is higher with ingested colloidal silver than topical colloidal silver.

Deciding to Take Colloidal Silver

Colloidal silver is not considered officially “safe” by the FDA, so consumers use this product at their own risk. Because of the mixed information available about colloidal silver, it can be difficult to decide whether this supplement is right for you. Before taking colloidal silver for any disease or condition, it is important to understand the potential side effects so you can be vigilant. It is also important to choose the colloidal silver product that poses the least health risk possible.

Colloidal silver products vary according to their composition. The exact effect and risk level of these products will be determined based on the size and shape of the particles used, as well as their concentration. Whether or not the colloidal silver particles are coated will make a significant difference in the product’s effects and safety level as well.

In general, it is best to choose coated colloidal silver over uncoated colloidal silver. The coating of colloidal silver particles prevents them from forming clumps, which reduces the risks associated with consuming them. Some of the primary benefits of coating include:

  • Reliable size uniformity – Coating keeps particles uniform in size so they won’t get trapped in tissue.
  • Stability – Coated colloidal silver is more stable and has a longer shelf-life.
  • Safety – Coated colloidal silver particles pose a lower risk of side effects than uncoated silver particles.


Keep in mind that not all coatings used on colloidal silver particles are the same. Likewise, because colloidal silver products are not standardized, it can be difficult to compare products between brands and be sure that you are receiving the same quality of colloidal silver every time you make a purchase. For this reason, choosing a reliable, trustworthy colloidal silver brand is essential.

Coated Silver is a coated colloidal silver formula with a high concentration and small, uniform nanoparticles of silver. This solution can be dissolved in almost any liquid, making it versatile regardless of your intended use. Contact us today to learn more!
