About Mesosilver

MesoSilver is 0.9999 pure silver in nanoparticle form

MesoSilver is an all-natural mineral supplement in the form of nanoparticle silver. It is an authentic nanoparticle silver product, meaning most MesoSilver consists of silver particles, not silver ions. Learn more. It has the highest nanoparticle concentration: 80% of particles (typical). Other nanoparticle silver products are only 10%.

Before wondering where to buy nanoparticle silver, read What is Ionic Silver? and learn what other producers of nanoparticle silver products don’t want you to know.

MesoSilver has the highest bioavailability of other nanoparticle silver products due to sub-nanometer size particles, whose diameter typically measures 0.65 nm or less.

MesoSilver tastes like water to most people – though a slight metallic taste is typical for some. See the FAQ page for more details on taste.

Nanoparticle Silver Products with a Powerful Combination of Properties!

MesoSilver combines small particle size and high particle concentration, a powerful combination of properties, to produce a nanoparticle silver product with the highest particle surface area of any other nanoparticle silver product ever tested. The Comparison Table shows how the particle surface area of Mesosilver compares to other nanoparticle silver products. To understand why the surface area of silver particles is the key to nanoparticle effectiveness, read Nanoparticle Silver Effectiveness.

Safety and Storage

Mesosilver is manufactured in an FDA-registered facility, has no potentially dangerous protein additives (mild protein), and is non-toxic. See the Safety Data Sheet (SDS).

These nanoparticle silver products do not interact or interfere with any medications and are made using the highest purity, sterile reagent-grade deionized water. MesoSilver’s concentration is 20 ppm (minimum) total silver.

  • Our nanoparticle silver products will not cause argyria, a discoloration of the skin caused by some forms of silver (protein products).
  • No adverse side effects have ever been reported from our nanoparticle silver products.
  • MesoSilver contains only pure water and pure silver.
  • Does not require refrigeration after opening.
  • Infinite shelf life.

Do Not use Nanoparticle Silver Products if You are Allergic to Silver!

Allergic reactions to silver, while not unheard of, are uncommon. Someone allergic to silver would be unable to handle a metallic silver object, such as silver jewelry, without causing an allergic reaction. Those uncertain if they are allergic to nanoparticle silver products should apply a few drops to the back of the hand to see if an allergic reaction results. If you do not see a reaction within 30 minutes, you can be reasonably confident that you are not allergic to silver.

Feeling Worse Before Feeling Better?

Some users experience a Herxheimer reaction when using nanoparticle silver products. This is a temporary and normal reaction to the healing process.

It is a reaction that occurs when the body is detoxifying and the released toxins which can produce headaches, body aches, joint pain, sweating, general malaise, sore throat, nausea and/or flu-like symptoms. More details.

Scientific Advancement

Mesosilver brand nanoparticle silver is the result of thousands of hours of research and development conducted at the Colloidal Science Laboratory, Inc. (CSL) over several years. Purest Colloids, Inc. is the exclusive worldwide producer of MesoSilver. The resulting product, with a particle surface area many times greater than other products of this type, provides more usable silver to the body. To better understand how to compare nanoparticle silver products, see How To Compare Nanoparticle Silver Products here.


The dosage for Mesosilver is typically between one teaspoon (5mL) and one tablespoon (15mL) daily to help maintain health. One tablespoon taken up to 4 times per day may be taken to help fortify the immune system when needed. The actual dosage will vary based on individual needs. At any higher amount, a probiotic should be taken away from the silver to minimize the impact on the gut flora.

A 500 mL bottle will provide a one-month supply when used at a dosage of one tablespoon per day.


MesoSilver is a clear amber-colored liquid, unlike most nanoparticle silver products, and looks like dark iced tea. The very high concentration of Mesosilver particles, not size or contamination, gives Mesosilver its distinctive coloration.

Previously, it was thought that such a dark color indicated the presence of large silver particles, which is the case for nanoparticle silver produced by methods other than the mesoprocess. The small size of the silver particles is confirmed by using a state-of-the-art scientific instrument designed specifically for measuring such small particles. Produced by Malvern Instruments, Ltd. of the United Kingdom, the High-Performance Particle Sizer (HPPS) can measure nanoparticles down to 0.6 nm diameter. The particle size report from the Malvern HPPS indicates that the size of the silver particles in Mesosilver is 0.65 nm in diameter, or only slightly more than two times the diameter of a silver atom making these particles the smallest silver particles of any product on the market.

Once the bottle is opened, the color of MesoSilver may change to gray depending on the atmospheric pollutants in the air. This color change does not indicate a problem with the nanoparticle silver product and is no cause for concern. The effectiveness is not affected. The color change to gray is commonly found in large cities like Boston, New York, Chicago, Los Angeles, Detroit, Denver, and many California cities.
