Colloidal Silver has had a long running love-hate relationship with most people. Though a generalisation, those of us who understand the limitations and applications of colloidal silver love it, those who understand it less or who have never heard of colloidal silver, inevitably jump on the hate bandwagon.

A brief history of silvers use.
Since around the early 1600’s silver was considered as a medical metal. Physicians of the day noted that implements that had been made from silver would resist the growth of bacteria (fungus by modern terminology). It was during the mid to late black death period in London that this attraction to silver by the learned physicians started to take a foot hold.

In more modern pioneering times, a silver coin was often dropped in to a bottle of milk in that it would prevent the milk from souring as fast as it would otherwise do. This could in some cases increase the life of the milk by as much as 7-10 days without refrigeration. It must be stressed however, that today’s silver coins are not made from pure silver as they would have been in times past. Today they are mostly sterling silver and are always coated with a protective layer to preserve their luster.

Though unconventional for the times, silver powders, fine ground flour with silver fragments, were used during some periods in history as first aid to stop bleeding and presumably to curb infection. Silver impregnated dressings are today commonplace in the military and medical fields.

Colloidal silver has its place in every ones life.

It’s kind of confusing to me how people shy away from colloidal silver because for the last 25 years or so I have used it on an almost daily basis for ailments and prevention of ailments with invariably great success.


So for me at least, the issue isn’t if colloidal silver is good or bad, it’s if the method of its production is good or bad.

Let me explain..

What is Colloidal Silver.
In its most basic form, colloidal silver is a solution of liquid (most commonly water) that has silver particulates suspended in it. That’s it in a nutshell. The term colloid is used to describe a particle of some other material (in this case silver Ag) that is small enough in size that once suspended in water, it will remain there simply by the electromagnetic force interaction between the liquid and the particle. If the particle falls or is separated from the water due to gravity it is not a true colloid.

It is also important to point out here, that silver colloids are 100% intact particles of silver, they are atomically stable with no missing or added electrons. They are physically particles, fragments of Ag silver.

What is Ionic Silver.
Ionic silver is a different thing altogether than colloidal silver. Ionic silver is produced when a silver molecule losses or ejects one of its electrons, most commonly the outer electron. This loss of that single electron transforms the molecule from a particle to an ion. This is an ionic silver and is not the same as a silver colloid.

BOTH IONIC and COLLOIDAL silvers have their place

Fantastic additional information on the use of silver in medicine can be found here.

So why do I say it’s in the method of its production that makes colloidal silver good or bad?

This is the kicker…

There are currently no regulations in any country worldwide that requires a license or any other means of validation to support manufacturers claiming they produce colloidal silver machines.

It is a real shame that the production at home of colloidal silver can be abused by those who have remembered a little bit of high school physics. The problem that we face though is that this high school physics isn’t what’s needed to produce colloidal silver.

The latest buzzword in the colloidal silver arena has to be “nano“. Now I don’t mind its use when it is used correctly or in context, but it really grates me when it is used by people who push these elementary principal “nano colloidal silver generators“.

This setup will NOT produce Colloidal Silver… maybe poor Ionic though.

Simply because an object is too small for the human eye to see this does not by default make that object “nano” sized.

In this 3x9volt battery example, this unit will not produce colloidal silver (only very poor ionic silver) and will never produce nano particulate colloidal silver. There is an absolute void of any technology in this example setup to produce a single effective silver colloid… of any size. Yet people will buy in to this.

The smallest object the naked eye can see is 0.1mm in diameter… a nano colloid would be 10-9 in comparison. 1 nm = 1.0E-6 mm… they’re small.

The Renewedcell Colloidal Silver generators are very different. They use a predominantly software driven process that slowly releases the silver particles in to the water rather than “blasting” them off. This they call their low voltage (12Vdc) slow release process. High voltage agitation (above 24Vdc) of the silver atoms can cause them to come apart in “clumps” (groups of particles) rather than the more consistently sized and individual particles from the low voltage set up.

This method of low voltage – slow release has been demonstrated to produce far greater numbers (up to 300x more) of silver particles per any given volume of liquid than from a high voltage process.


Don’t Believe The Size Hype

Though it is often claimed that smaller silver colloids are better, this isn’t the full story. Yes smaller is better.. but to a point. Silver colloids in the 5-15 nanometer size fall in to the “goldie locks” range. They are not too small nor are they too large, just right. For solutions that are intended to combat bacteria specifically, colloids up to 100nm are perfectly fine.

Given that the human DNA helix is 2 nanometers (2nm) in diameter and the average bacterium is 1um (1 micrometer) in diameter, claims of 1nm colloids being the best colloid size you can make is very misleading.

The size issue is important because of how silver reacts with a bacterium cell. Silver “kills” the virus/bacterium by amalgamating the virus/bacteria cell in to the silver particle and thus removing the virus/bacteria’s ability to absorb oxygen.

1nm silver particles are too small to fully amalgamate with a virus cell that is minimum 10 times larger than itself and is thus is never going to kill the virus, let alone have a look in at killing a bacteria.

A silver colloid can amalgamate a cell that is between 2 and 4 times the colloids size, that’s it, no larger. The Renewedcell silver colloids are demonstrated and measured as being between 4nm and 12nm in diameter. The larger colloids of this range are produced first in the process of producing the colloidal silver. While there is a larger electrical resistance between the two silver electrodes (the silver rods) more current is needed to bridge that gap and thus larger colloids are formed. As the resistance between the electrodes reduces (as more colloids are released) the current can flow easier and thus smaller colloids are produced.

Smaller Isn’t Always Better

We should also consider that smaller silver colloids (less than 5nm) have a significantly lower electromagnetic force and will not be able to attract or be attracted to other cells in the same way, for example, a 6nm silver colloid would be able to. The attraction force of a particle is not linear. For example, a 10nm colloid will have over 4x more attraction force than a 5nm colloid.

So ultimately, you can purchase a solution of colloidal silver that is rated at, let’s say, 50 Parts Per Million (PPM) of 1nm silver colloids, and this would be far less effective than, let’s say, a solution at 15PPM of 10nm sized colloids.

There is also the upper size of the colloids to consider. Colloids that are too big (above 20nm) will not be able to pass through some tissues within the body (blood-brain barrier for example) and will be caught and expelled from the body before it has done any effective work.

There’s only 1 manufacturer who is pushing for regulation.

Based in Australia, Renewedcell is the only manufacturer (that I am aware of) that is pushing for the regulation of the manufacture and claims thereof of colloidal silver generators/machines and bottled colloidal silver solutions.

“We welcome regulation in the colloidal silver space, as to us this will weed out the false claims and in some cases outright lies that are a plague to us all.”

In an email response from Lucy Hovind, marketing officer at Renewedcell, when I asked about their thoughts on regulation she stated;

“We have already gone through all of the testing and independent analysis of our solutions prior to us releasing our machines to market.. we can support our claims and challenge anyone to do the same for theirs.”

What does this mean to us then?

  • if they (Renewedcell) want regulation, they must be ready for it
  • they must have the technical means to support their claims
  • their solutions must be what they claim they are
  • you get what you pay for

This is why we only recommend the purchase of an Ionic & Colloidal Silver or Colloidal Silver generator from Renewedcell.

UPDATE
I’ve been informed that in late 2018 or early 2019 Renewedcell will be releasing their own proprietary colloidal silvers manufactured on an alkaline based solution. Currently I can confirm that the solutions are undergoing independent validation trials. Unless there is a marketing change between now and the final release date the solutions will be called Nano-15TM. This I’m presuming will denote the PPM count. I’ll keep you posted once I know more.
