Crystal colloidal silver

Our colloidal silver is real colloidal silver, which means that the greatest part of Crystal colloidal silver consists of silver particles and not of silver ions. Our colloidal silver tastes like water, but a slightly metallic taste is also not unusual.

Crystal colloidal silver has a concentration of 10 ppm (10 mg/l), consisting of 80.5% colloidal silver particles with a particle size of 0.65 nanometres. This composition ensures that Crystal colloidal silver has the highest effective surface area of 7.1 m2/litre.

We analyse the quality of our products on an ongoing basis to ensure that we can guarantee the highest concentration of colloidal silver particles in the world, namely 80.5%. We also analyse the quality of products from other suppliers, and the results for many suppliers are shocking. The highest colloidal percentages they supply are no more then 10%.

Three types of ‘colloidal’ silver?

There are presently three different types of ‘silver water’ products on the market that are sold under the name of ‘colloidal silver’, namely ionic silver, protein silver, and real colloidal silver. Consumers looking for real colloidal silver are being taken advantage of because ionic silver and protein silver products are being marketed as real colloidal silver. A brief explanation of these three types and the difference is provided below.

Ionic silver

Unfortunately, most of the products sold as colloidal silver consist of ionic silver. The composition of these products consists of at most 10% real colloidal silver and at least 90% silver ions. The producers of ionic silver claim that colloidal silver should look like clear water, but that is simply not true. Companies that sell ionic silver and claim that their product is actually real colloidal silver are simply trying to confuse you, the buyer. Don’t be fooled. If the product is transparent and colourless, then it’s ionic silver and not real colloidal silver.
Question: Would you feel cheated if you were to buy a pack of freshly pressed orange juice containing only 10% freshly pressed orange juice and 90% water?

The difference between ionic silver and colloidal silver

The difference between ionic silver and colloidal silver is due to the difference between the particles. Ionic silver is silver dissolved in water, in other words a solution of ‘silver ions’ in water. Colloidal silver is a suspension of silver particles in water. Silver ions react with chlorine atoms in the body to form silver chloride; silver particles do not. The effect of silver chloride inside the body is totally different than the effect of colloidal silver.

Real colloidal silver

Unfortunately, due to the high complexity of the production process and the associated high level of costs, products with real colloidal silver are the hardest type of colloidal silver to find on the market. Real colloidal silver is a suspension of tiny particles of silver in water. In order to comply with the technical definition of colloidal silver, these particles must be larger in size than 1 atom of silver and smaller than 100,000 nanometres. In our opinion, only products containing more than 50% of colloidal silver particles may be sold as colloidal silver. Crystal colloidal silver contains 80.5% colloidal silver.

Protein silver

After ionic silver products, silver protein products are the next most common type of product marketed as colloidal silver. These products are easy to recognise due to their concentration, which is 30 ppm or higher. Silver protein consists of large silver particles and a binding agent in the form of a protein. The binding agent keeps the large particles floating in the suspension. Silver protein is very easy to produce by simply adding water to silver protein powder, which can be bought from various chemical companies. We strongly advise you not to use silver protein products due to the often high concentration, the very large size of the silver particles, and the protein binder contained in these products.

Complete transparency regarding our quality

In the following, we explain which 4 specifications determine the quality of colloidal silver. Why does Crystal say that the ppm (parts per million) concentration, by itself, says nothing about the quality, and what is the total particle surface area?

Quality based on specifications

In order to be sure that you are buying the highest quality of real colloidal silver available, you need to know 4 product specifications. After years of analysing the products available on the market, Crystal has not come across a single supplier that supplies colloidal silver water with a quality equal to that of Crystal colloidal silver.

Which 4 specifications do you need to know?

1. Concentration (mg/l) ppm

2. Particle size

3. Composition, colloidal vs ionic

4. Particle surface

Concentration in ppm (mg/l)

Crystal colloidal silver has a concentration of 10 ppm, but what does 10 ppm mean exactly and why do we say that this measure by itself says nothing?

For liquids, the concentration in ppm (parts per million) is the same as milligrams per litre (mg/l).

For many producers, ppm is the “Unique Selling Point”, and it is often the only specification mentioned on the packaging or on the website. For many users of colloidal silver, ppm is a measure of quality: the higher the ppm, the better the quality. Although many producers want you to believe this, it is absolutely not true!

The ppm concentration alone says nothing about the quality, as explained in the example below. As an example, let us consider Crystal colloidal silver with a concentration of 10 ppm or 10 milligrams of silver per litre.

Imagine that we put 1 particle of silver weighing 10 milligrams in 1 litre of water. We would then have a silver concentration of 10 ppm or 10 milligrams of silver per litre of water. Now if we divide that same piece of silver into billions of tiny silver particles and we suspend all those colloidal particles in 1 litre of water, we would still have a liquid with a silver concentration of 10 ppm or 10 milligrams of silver per litre.

But of course the liquid with billions of tiny particles is much more effective. The only difference between the two liquids is the size of the particles into which the 10 milligrams silver per litre is divided. This is what we mean when we say that the concentration of silver in ppm, by itself, says very little about the quality of the product.
This brings us to the particle size.

Particle size

Crystal colloidal silver consists for 97% of silver particles with a particle size of 0.65 nanometres. These particles consist of approximately 19 to 20 atoms of silver. The remaining 3% have a particle size 2.8 nanometres. Physically speaking, it’s impossible for smaller particles of silver to exist suspended in water simply because the laws of physics don’t allow it. In other words, the silver particles in Crystal colloidal silver are, physically speaking, of the smallest possible size. This is also one of the reasons why the colloidal silver we supply is of the best possible quality, bar none. It’s the particle size that determines the effectiveness of colloidal silver. After all, the tinier the particles, the more particles there are per weight of silver and the more effective the colloidal silver will be.

From 1984 to 2000, Professor Ronald J. Gibbs was director of the Centre for Colloidal Science at the University of Dalaware. His book contains the following quote:

"The size of the particles in colloidal silver suspensions we use, are very important. Particle size controls the effectiveness of the colloidal silver suspension"

Composition: colloidal versus ionic

How do we determine which liquids can be called ‘colloidal silver’?
If a liquid contains more than 50% colloidal silver and therefore less then 50% ionic silver, it can be called colloidal silver.

Crystal colloidal silver contains 80.5% colloidal silver and 19.5% ionic silver. Our colloidal silver contains a certain percentage of ionic silver, as ionic silver is always produced during the production process of colloidal silver. Ionic silver and colloidal silver are in no way comparable in terms of their effectiveness; they are two completely different substances. A study carried out by Hogeschool Zuyd (Zuyd University of Applied Sciences) in Heerlen, the Netherlands, concluded that most of the products on the market contain only 10% colloidal silver and 90% ionic silver.

Total surface area

The total surface area, which is the sum total of all the surface areas of the individual particles, is the most important specification that determines the quality of colloidal silver water. For Crystal colloidal silver with a concentration of 10 ppm, the total surface area is no less then 7.1 m2/l. The greater the total particle surface area, the more effective the colloidal silver is. The total surface area is the most important measure of the quality of colloidal silver, and it is determined by the specifications of the colloidal silver. The better the specifications are, the better the colloidal silver is.

The total particle surface area is determined by the concentration of silver in ppm (mg/l), the particle size, and the percentage of colloidal silver. The ionic silver does not count in this regard, as it consists of dissolved ions and not of particles. The smaller the particle size, the more particles there are and the greater the total surface area of all the particles, in other words the effective particle surface area.

The least expensive colloidal silver

The figure above provides an overview of the price/quality ratio of our colloidal silver. The figure makes it clear that the price of Crystal colloidal silver per particle surface area is the lowest. You can find more detailed information in the reports prepared by Hogeschool Zuyd.

Quality testing by Hogeschool Zuyd (Zuyd University of Applied Sciences)

Hogeschool Zuyd has carried out a study into the quality of various colloidal silver and silver cream products from Dutch suppliers. Some of the conclusions from their study are presented below; you can also find these conclusions in the original report. You can download the complete report by clicking on the ‘download report on silver’ link given below the conclusions.

Conclusions report silver

1. Only Crystal delivers a product where the specified concentration of silver and the measured concentration of silver match.

2. If we assume that a colloidal silver product should consist of more than 50% colloidal particles and less than 50% ionic silver, Crystal is the only supplier that provides colloidal silver.

3. The specified particle size of the product is only guaranteed by Crystal and it is way smaller than the particle size of the other suppliers.

The colour of colloidal silver

Crystal colloidal silver is a clear, amber coloured liquid. You can easily see whether you have purchased real colloidal silver by simply looking at the colour. Real colloidal silver is, in fact, an amber coloured liquid that reminds one of cooled tea. Real colloidal silver thanks is characteristic colour to the high concentration of silver particles, and it is these silver particles that give the product its characteristic colour. In contrast, most of the so-called colloidal silver products on the market consist of a liquid that looks the same as water. These products contain ionic silver instead of colloidal silver, and sometimes even that is missing.


According to European Regulation EC no. 1925/2006, producers of colloidal silver in Europe are no longer permitted to sell this product as a dietary supplement in water. But rest assured, the composition of Crystal colloidal silver has not changed. The only thing that has changed is its European classification.

We must therefore inform you that the old daily dosage mentioned below is no longer applicable, even though the composition of the product is still the same. 1 to 4 teaspoons 4 x per day, to be placed beneath the tongue for a few minutes before being swallowed.

The instructions for use have now been revised as follows.
Crystal colloidal silver Medical Device Class 1.
Mouthwash and gargle. For the treatment of skin disorders.

Skin discolouration, also called Argyria

Crystal colloidal silver is real colloidal silver and does not cause any skin discolouration (argyria). Argyria is a skin condition in which the skin becomes blue-grey in colour. Most people are familiar with the story of Paul Karason, called the ‘Blue Man’ in the media. The story of the Blue Man was a ‘fake story’, made up by an advertising agency and paid for by a pharmaceutical company. The goal of this campaign was to make people afraid of using colloidal silver. The tactic used was based on the claim that the condition of the Blue Man was caused by the use of colloidal silver. The entire story was a complete hoax.

He developed the condition because he used a self-made silver solution, which most probably contained a high concentration of ionic silver as well as large particles of silver (larger then 500 nanometres).

Crystal colloidal silver is real colloidal silver with silver particles measuring only 0.65 nanometres and does not cause any skin discolouration.

Shelf life of colloidal silver

Crystal colloidal silver is made of a noble metal, and as a result Crystal colloidal silver has an unlimited shelf life. Nevertheless, we recommend a maximum shelf life of 3 years. The above applies only if the product does not become frozen. Freezing makes colloidal silver ineffective and worthless.


Crystal colloidal silver does not need to be stored in a cooling.
For maximum shelf life, we recommend that you:

- Do not drink from the bottle of colloidal silver but instead use the small spoon or pipette provided with the product.
- Do not return any unused colloidal silver into the bottle.
- Store colloidal silver at room temperature.
- Avoid exposing the product to direct sunlight.

The packaging

As made clear above, Crystal focuses on quality. This quality is reflected in the specifications of the colloidal silver as well as in the packaging. It’s important to deliver quality, but it’s just as important to ensure that the product retains its quality during use. Accordingly, our 200 ml bottle of colloidal silver comes with a handy fliptop cap that makes it very easy to use. In addition, our 200 ml bottle also comes with a small spoon and pipette. The 1000 ml bottle of colloidal silver comes with a free refill set, consisting of a 100 ml bottle with handy fliptop cap, atomiser, small spoon, and pipette.

Contraindications for colloidal silver

f you are allergic to silver, then you should not use Crystal colloidal silver. Although allergic reactions to silver are rare, they are not unknown. If a person is allergic to silver, he or she is not able to wear objects made of silver. If you are not sure whether you are allergic to silver, you can apply a few drops of colloidal silver to the back of your hand. If, after 30 minutes, you do not notice any reaction, then you can be sure that you are not allergic to silver.
