MesoSilver is the Most Effective Colloidal Silver

Many products are advertised as being colloidal silver, but in fact are mostly ionic silver solutions. A true silver colloid consists mostly of silver nanoparticles. Learn The Truth About Ionic Silver that other producers don’t want you know.

MesoSilver has the highest percentage of its silver content in the form of silver nanoparticles, not silver ions. See the Comparison table »

Because MesoSilver has a much higher particle surface area than any ionic silver product, one would expect that the antimicrobial effectiveness would likewise be much greater. The graph confirms the greater effectiveness of MesoSilver vs. the ionic silver product as would be expected based on the greater particle surface area. Read More »


MesoSilver, MesoGold, etc. Are Non-toxic

MesoGold, MesoSilver and MesoPlatinum are made of noble metals, MesoZinc, MesoCopper and MesoSilica are made of metals that are essential for human body, and all of them, when used in colloidal form are non-toxic. When used, the noble metals do not cause heavy metal poisoning and in form of particles they do not accumulate in body tissues or any organs. Read More »

Purest Colloids, Inc. hired one of the leading independent laboratories in the U.S. to do a toxicology study on the colloidal silver product, MesoSilver. As a result of the test work, the independent laboratory made the following conclusion, “Under the conditions of this study, there was no mortality or significant evidence of toxicity observed in the rats. The test article MesoSilver would not be considered toxic at a dose of 5g/kg by oral route in the rat.” Read More »

What Are Mesocolloids?

Mesocolloids consist of pure elemental metal nanoparticles dispersed in ultra pure deionized water. The smallest sized nanoparticles are called mesoparticles. Mesoparticles are very small particles whose size is greater than a single atom but smaller than conventional small particles. Size ranges from sub-nanometer to 10 nanometers in diameter and mesocolloids typically consist of 10 – 30 000 atoms per particle. Colloids consisting of mesoparticles have a particle surface area that is many times greater than colloids produced by other methods and are called mesocolloids. Read More »

Mesocolloids Combine

  • small particle size and
  • high concentration of particles

Mesocolloid is a trademarked name that refers to an entire group of metal colloids that are produced using the mesoprocess. The term mesocolloid was coined by the scientists at the Colloidal Science Laboratory (CSL) who developed the method of producing colloids consisting of mesoparticles.

Meso-World animation shows the relative size of the silver particles in MesoSilver.

Colloid Effectiveness Is Determined By Particle Surface Area

Compared to colloidal products produced by other methods, Mesocolloids have the highest particle surface area because of the combination of small particle size and high concentration of particles. See the Comparison Table for comparative examples. Mesocolloids are characterized by the small size of the mesoparticles that constitute the colloid and the high percentage of particles vs. ions. Read More »

Mesocolloids Have The Highest Particle Surface Area

For a constant concentration of metal nanoparticles, the particle surface area increases as the particle size decreases. In the chemical world, reactivity increases with increasing surface area. Therefore, the effectiveness of colloidal solutions increases with decreasing particle size as the particle surface area increases. For this reason, particle surface area serves as a metric for comparing colloidal solutions. In metal colloids the increase in reactivity that derives from the increased particle surface area translates directly to effectiveness of the colloid. Surface area is expressed in square centimeters (cm²) per milliliter (ml) of colloidal solution, and is written as (cm²/ml). Read More »


Research And Expert Opinions

According to experts, no microorganism ever tested has been able to stay alive for more than six minutes when exposed directly to colloidal silver.

In laboratory tests with colloidal silver, bacteria, viruses, and fungal organisms are killed within minutes of contact. Larry C. Ford, M.D. of the Department of Obstetrics and Gynecology, UCLA School of Medicine, Centre For The Health Sciences reported in November 1, 1988, “I tested them (the silver solutions) using standard anti-microbial tests for disinfectants. The silver solutions were anti-bacterial for concentrations of 105 organisms per ml of Streptococcus Pyogenes, Staphylococcus Aureus, Neisseria Gonorrhea, Gardnerella Vaginalis, Salmonella Typhi and other enteric pathogens and fungicidal for Candida Albicans, Candida Globata and M. Furfur.”

Alfred Searle, founder of the giant Searle Pharmaceuticals (now Monsanto) stated, “Applying colloidal silver to human subjects has been done in a large number of cases with astonishingly successful results. For internal administration … it has the advantage being rapidly fatal to pathogens without toxic action on its host. It is quite stable.” Further information indicates that Colloidal Silver does not cause harmful interactions with other medications or topical treatments.

Although scientists and health professionals have warned about the rise of “supergerms”, microbes that have become resistant to antibiotic treatments, bacteria seems unable to build up a resistance to silver. Unlike some other metals, silver is not poisonous to the body – only to harmful microbes. It is also not addictive, and is very difficult to overdose on. In addition to hundreds of years of practical use, recent scientific studies on humans and animals have shown that wounds treated with silver heal at a faster rate than those treated without silver. Read More »

According to many studies, colloidal gold increases mental acuity and the ability to concentrate. Colloidal gold is thought to strengthen mental function by increasing the conductivity between nerve endings in the body and on the surface of the brain.

Gold is also used in the treatment of several forms of cancer. Injection of microscopic gold pellets helps retard prostate cancer in men. Women with ovarian cancer are treated with colloidal gold, and gold vapor lasers help seek out and destroy cancerous cells without harming their healthy neighbors. Read More »
