The Colloidal Silver Buyer’s Guide

by Dr. Edward Group DC, NP, DACBN, DCBCN, DABFM Published on , Last Updated on


Google ‘colloidal silver’ and you’ll get nearly 2.4 million results. There’s a lot of products, information, and mis-information out there. Here’s a simple guide to help you understand the different names, types, and key factors to find the best colloidal silver product for you.

Colloidal Silver History

As recently as the 1920s, colloidal silver was used to fight infection. In the 1800s and early 1900s, silver coins would be dropped in milk to keep it from spoiling. Infants have been fed with silver spoons for centuries as a protective measure. The only problem with silver is that it’s an element and not a patentable substance. That means Big Pharma can’t make money on it, and you’ll find when Big Pharma can’t make money on a medicine, central governments generally oppose it.

Silver has been used for thousands of years. Now, in the 21st century, technology has made silver even more available. Here’s what you should know before you buy colloidal silver.

What Does Colloidal Mean?

Colloidal could be considered an alternative name for ‘particle.’ This is because a true colloidal silver product will contain silver particles. Ideally, you want to look for products containing nanoparticles. More on that in a moment. Three types of products are often sold as colloidal silver. These are ionic silver solutions, silver protein solutions, and true colloidal silver. Here’s an overview of each:

Ionic Silver Solutions

These products contain both silver particles and silver ions. As a general rule, about 90% of these solutions are ionic silver. Ionic silver solutions may also be called monatomic silver, silver hydrosol, or more recently covalent silver.

Silver Protein Solutions

These solutions contain silver particles and a protein binder. They may be labeled as Silver Protein or Mild Silver Protein. Silver particles in these solutions are generally large which is why they require a protein like gelatin. The need for a protein increases the danger of bacteria contaminating the solution. Because of the large size of the silver particles, a solution containing silver protein may not be safe and could lead to a condition known as argyria.

True Colloidal Silver

Silver nanoparticles make up the majority of true colloidal silver. More than 50% of the silver content will be silver particles with the remaining 20-49% of silver being ionic silver. What is the difference between a silver ion and a silver particle? A silver particle, or nanoparticle, is usually a complete atom of silver. This differs from a silver ion, which is a silver atom with an extra electron gained when it binds to a water molecule.

How to Identify a Safe Colloidal Silver Product by Color

Ionic silver and true colloidal silver solutions vary from clear to a dark color. The darker the color, the higher the concentration of silver particles which block light trying to pass through the solution. But you need to be wary of dark solutions. Silver protein solutions range in color from an amber hue to a dark, almost black color. If you’re not sure by the color, shake the product. A silver protein produces a foam that will last for several minutes after being shaken.

What Particle Concentration is Best?

Particle concentration doesn’t necessarily determine the effectiveness of a product, but it can help clue you in on the type of product it is. Ionic silver and true colloidal silver generally contain in the range of 3 to 20 ppm (parts per million). Silver proteins contain 30 ppm up to 20,000 ppm. Concentrations at this level are not considered safe.

Particle Surface Area

What makes a colloidal silver product effective is its surface area. The greater the available surface area, the greater amount of surfaces of harmful organisms that can be contacted. To illustrate this, think of a silver dollar. A silver dollar contains roughly 27 grams of silver with a surface area of about 28 square centimeters. Break up all the silver particles into their atomic form, and the surface area of all those silver particles can be measured in acres!

Can You Make Your Own Colloidal Silver?

It’s true you can buy your own generator and make home-made colloidal silver solutions. First, you should never make a silver solution using silver salts or silver proteins. Issues such as contamination, the silver particles being too big and ineffective, and argyria are common concerns.

As for the generators–while you could attempt to make your own solutions at home, there are considerations to make. You’ll need to invest the time and money to get the equipment and learn how to use it. You’ll also need to ensure a sterile environment. Most importantly, you’ll need to ensure the purity of the colloidal silver product. Or, you can save yourself a lot of time and money and try Silver Fuzion® instead.

    Most of the most common silver compounds are photosensitive.
    This being the case, it is pretty obvious that anyone who makes a silver solution using tap water, full of chlorine and fluorine, probably deserves to look like a smurf. This being said, don’t buy your solution from someone who has blue skin:-) On the other hand, I have made and consumed silver solutions that were made with store-bought distilled water. I don’t see any reason why particle size would have anything to do with purity of the water used, whereas nanoparticles are usually produced by very high voltages, which would negate the need to add an accelerant that could produce a photosensitive silver compound. I have always used three “9-volt” batteries and silver bezel to make my silver solution, and patience precludes the need to add anything to the distilled water. Whether an accelerant is added or not, the best way to speed up the making of silver solution, in my experience, is to use a little bit of the previous batch as a starter. This will lead to the dilution of whatever deleterious silver compounds might be in the solution.
    As to strength, I’m a believer in making and using silver solutions that are as strong as you can stand, tastewise. I don’t use anything which has changed from white to darker, as I’d take that as an indication that photosensitivity has occurred.
