Purest Colloids true colloidal silver is 90% sub-nanometer particles of pure silver. The smallest particle size available anywhere. No other colloidal silver product can make this claim.

The extremely small particle size (0.65 of a nanometer) is due to a unique manufacturing process which does not involve electrolysis.
Nearly all products called colloid silver are not, this might sound a bold statement but it is true.
It is not possible to make true colloid silver using electrolysis.
Products manufactured using electrolysis are IONIC SILVER SOLUTIONS some of these can be improved in particle content by a process call reduction. When applied to ionic silver solutions reduction is normally applied using a carbohydrate such as glucose or high fructose corn syrup.
The reaction is not easy to consistently control, but when properly carried out can produce silver particles in an ionic solution. The downside is the particles are MASSIVE and not consistent in size.
Of course the manufacturers of these products will be proud to have created particles as small as 23 nanometers, and when this is expressed as decimal parts of a millimetre it sounds a very small number.
Many competing products are only 10% particulate silver , these are not true colloids, some  particles are as large as 800 nanometers will not remain in suspension.
Quite apart from whether a product is actually a colloid or not, and most others are not, particle size is very important. In antimicrobial effectiveness terms a .65 nanometer particle is thousands of times more effective than a 23 nanometer particle. Particle size is discussed in more detail here >>

Purest Colloids manufacture an extensive range of products for different applications all containing their Mesosilver nanoparticles of pure silver, as well as 20ppm Mesosilver for all uses, there is a 30ppm anti-fungal spray and a variety of creams for burns, skin irritations, acne and minor wounds. 

Silver uses
Colloid silver is typically used in a wide variety of antimicrobial applications.
It is antibacterial antiviral and anti fungal, it kills on contact 650 bacteria which is a useful quality in this day of antibiotic resistant bacteria. Unlike antiseptics Colloidal silver is painless when applied to cuts bruises or burns it does not destroy tissue cells. It can be used in sensitive areas without causing pain or stinging.
Silver based compounds are used in hospitals to promote healing in cases of burns and serious wounds.
It is reported to be effective in treating a wide variety of bacterial viral and fungal infections.
In spray form is effective in a wide variety of home sterilisation applications such as hygienic surface cleaning, and to prevent the spreading of bacterial contamination sanitary ware cleaning door handles etc.
It can be used in water sterilisation hot tub and pool cleaning as well as to reduce bacterial proliferation in many common household items, such as toothbrushes, cutting boards, sponges etc.
Gargling with it at the advent of a cold flu or similar infection can dramatically reduce or clear the infection if caught son enough.
In food preservation it can be sprayed onto the top of jam in jars before closing after use to prevent mould growth.

  • Avoid storing Mesocolloids at temperatures exceeding 27 deg C
  • Do not freeze
  • Avoid direct sunlight
  • Do not drink directly from the bottle
  • Once decanted do not pour unused liquid back into the bottle 

Shelf Life

  • Unopened, as long as the above conditions are adhered to, Mesosilver will keep indefinitely.
  • Opened - Use within 1 year.


The dosage for Mesosilver is typically between one teaspoon (5ml) and one tablespoon (15ml) daily to help maintain health. One to four tablespoons taken 4 times per day may be taken to help fortify the immune system when needed. Actual dosage will vary based on individual needs.
A 500 mL bottle will provide a one month supply when used at a dosage of one tablespoon per day
