The Nonexistent 'Colloidal' vs. 'Ionic' Silver Controvery and Dr. Rima Laibow (August 12, 2014)

Hi Ken,

Just needing a bit of clarification re: CS versus nano-silver. These days, several alternative practitioners are claiming that colloidal, or ionic, silver is outdated, and that nano-silver is the "next generation" of silver, and is FAR more effective and safe. Here is an example from the website of one prominent alternative MD, Dr. Rima Laibow of Natural Solutions Foundation:


And the following site states:

Activz Silver is not Colloidal Silver or Ionic Silver - Activz Silver is the next generation of silver. The old technology of colloidal silver has been improved to create this next generation of silver products; Nano-silver. There’s 18 U.S. patents backing the safety and efficacy of this nano-particle technology.

Nano-silver: A thin multivalent silver oxide coating, built of numerous Ag404 molecules surrounds the metallic nano-sized silver core. With the Ag404 coating, the silver particle is attracted to the surrounding water molecules, and as such, becomes part of the structure of the water. This makes the silver much more stable and bioavailable than other forms of silver. Because of this difference, our silver particles have many qualities; qualities that each add up to create a unique silver technology.

Our silver particles are excreted from the body within 24 hours. Therefore, supplements made with our silver particles can normally be ingested daily as a dietary supplement without building up in the body.

Our silver particles reach their peak absorption in the blood stream within 2 hours.
Because of their multiple modes of action, you need less of our nano-silver particles to accomplish the same thing as you would with other ionic or colloidal silver particles; comparatively, the results are much less silver ingested.

Activz Silver works faster, longer, and is very efficient

After a cursory search of your site, I was unable to find much in the way of your opinion of nano-silver. Can you please comment?

Also, can you clarify what seem to be 2 conflicting statements on your site? In one place, you state:

"Colloidal silver produced with a relatively low voltage DC current, will produce a solution that has clusters of silver atoms joined together and will appear yellow in color".

In another, you state:

"all CS solution made with low voltage DC current are producing IONS of silver. The main reason that the silver atoms will remain suspended in a CS solution is due to the fact that they are ions and REPEL each other and therefore bounce all around the solution trying to get away from each other".

Many thanks,


Hi Marilyn,

After reading your email again, I see that I didn't completely answer you in the previous reply.

CS can be made using either DC or AC voltage. It can also be made using low, medium or high voltages of either DC or AC. You can get different parameters in properties when using different voltages and waveform type. The so called "nano" silver CS is made with high voltage AC. At very high voltage, you get smaller ions of silver going into solution. They are so small that they don't reflect light and the solution looks clear. There are a few misconceptions being promoted on the internet by self anointed experts on colloidal silver and Rima echoes those misconceptions in her statements.

"Colloidal" silver and "ionic" silver are not two different "things" as she states. They aren't nouns. They are adjectives.

1. All colloidal silver particles made with electrolysis create an "ion" when they come off the silver electrode -- without exception. The silver atom loses an electron from its outer orbit and becomes an ion with a net positive charge. Ions of the same polarity (positive charge) will repel each other in the solution, thus they become evenly distributed throughout the solution.

2. "Colloidal" refers to very fine particles in a liquid solution that are held in suspension in that solution. If the particles fall to the bottom of the glass or cling to the sides, then it's no longer a "colloidal" solution.

So "ionic' silver just refers to the fact that the silver atoms have lost an electron and are now in an "ionic" state and "colloidal" refers to particles in suspension. The "nano' silver that Rima is boasting about has been around for a very long time and is traditionally called "HVAC" silver, or High Voltage AC (AC means "alternating current"). Rima's "Activz Silver" is both colloidal and ionic, whether she realizes it or not.

When very high voltages are involved, additional compounds are formed with HVAC production. Very often, one electrode is placed in the water and the second electrode is held an inch or so above the water to increase arcing. Since air is mainly composed of oxygen and nitrogen, you get an increase of nitric acid in the solution as well as silver oxides, such as Ag404. If you sent a sample of their "Activz Silver" to a lab for analysis, you would get back a report that showed either zero or near zero in silver atoms, but a very high reading of nitric acid.

The silver oxide, per se, doesn't necessarily make the silver more bio-available, but smaller ion size is a legitimate factor is this regard. As far as stability goes, if you measure the ppm of a HVAC solution using a TDS meter, you will see that it will gradually decline as the months roll along. The high voltage employed instates a high level of energy in the electron cloud surrounding the silver atoms, but it doesn't remain in that high energy state for a long period of time. It gradually dwindles as the electron shells come down to a lower state of activity and the ppm will gradually decrease. You will get more activity if you use HVAC silver relatively soon after it's made. HVAC that's been in storage for a year or two will have much lower activity. Do you have any way of knowing when their stuff was made or how long it's been in storage? Of course not.

As far as 18 patents goes, I don't know. I'm dubious. Maybe they can supply the patent numbers and we can take a look at exactly WHAT was patented.

It takes about 2 weeks for the body to remove silver, whether it's called "nano" or not. The Silver Institute explained the mechanism in a 1998 paper. I have a copy. Her statement that their stuff clears out of the body in 24 hours is incorrect.

Colloidal silver made with low voltage DC will look yellow when made with distilled water. Anyone can make it themselves without any worries about the safety concerns involved when using high voltage AC (typically 10, 000 to 12,000 volts AC is employed). Low voltage DC Colloidal silver will deactivate just about every bug in the book. UCLA ran a lengthy test of low voltage CS in 1988 and wrote a report (since disappeared and now denied). Low voltage DC CS killed over 650 pathogens, their entire catalog.

Regards, Ken

PS. Rima was a psychiatrist, not a practicing "alternative" physician. All psychiatrists are required to get a MD in order to practice psychiatry. She's definitely 'prominent,' but for an entirely different reason. Her care in stating "facts" has been called into questions by the Dr Mathias Rath Health Foundation among others.
