About Mesosilver

MesoSilver is 0.9999 pure silver in colloidal form

MesoSilver is an all-natural mineral supplement in the form of nanoparticle colloidal silver. It is a true colloidal silver product, which means the majority of MesoSilver consists of silver particles, not silver ions. Learn more. In fact, it has the highest nanoparticle concentration: 80% of particles (typical). Other colloidal silver products are only 10%.

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

MesoSilver has the highest bioavailability of any other colloidal 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 normal for some. See the FAQ page for more details on taste.

Colloidal 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 colloidal silver product that has the highest particle surface area of any other colloidal silver products ever tested. The Comparison Table shows how the particle surface area of Mesosilver compares to other colloidal silver products. To understand why the surface area of silver particles is the key to colloidal effectiveness read Colloidal 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 Material Safety Data Sheet (MSDS).

These colloidal 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 colloidal 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 colloidal silver products.
  • MesoSilver contains only pure water and pure silver.
  • Does not require refrigeration after opening.
  • Infinite shelf life.

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

Allergic reactions to silver, while not unheard of, are uncommon. Someone having an allergic reaction to silver would not be able to handle a metallic silver object such as silver jewelry without causing an allergic reaction. Those who are uncertain if they are allergic to colloidal 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 fairly certain that you are not allergic to silver.

Feeling Worse Before Feeling Better?

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

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

Scientific Advancement

Mesosilver brand colloidal silver is the result of thousands of hours of research and development conducted at the Colloidal Science Laboratory, Inc. (CSL) over a period of 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 colloidal silver products, see How To Compare Colloidal 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 of the gut flor.

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


Unlike most colloidal silver products, MesoSilver is a clear amber-colored liquid, looking like dark iced tea. It is the very high concentration of Mesosilver particles, not size or contamination, that 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 colloidal silver produced by methods other than the mesoprocess. The small size of the silver particles is confirmed by the use of 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) is capable of measuring colloidal particles 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 found in the air. This color change does not indicate a problem with the colloidal 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 in many cities in California.
