Colloidal Silver FAQs

According to Dr Pedersen, there are no harmful effects on the gut microbiota. Colloidal silver only destroys pathogens with a primitive cell structure, thereby maintaining the sensitive balance of the intestinal flora by preserving the good bacteria. 

The only recurring side effect is argyria: argyria is characterised by a grey/blue colouration of the skin caused by very large doses of silver. 

No cases of argyria have been documented following the ingestion of commercially manufactured colloidal silver. The rare reported cases of argyria occurred following the domestic production of silver salts, which were then consumed in very high doses.

Since 1 January 2010, colloidal silver is no longer considered a dietary supplement by the European Union. In France, all manufacturers of colloidal silver have registered it as a cosmetic product, which implies that it can only be used externally. After all, who would drink a cosmetic product?

In many other countries, such as Switzerland, it is considered a dietary supplement, so it can be ingested.

There is a page with more information on this topic. 

Contrary to what you may have read, colloidal silver is not banned: it is sold as a cosmetic product by the manufacturers, which implies that ingestion is not permitted. Ingestion is prohibited throughout the EU following its status change in 2010.

To our knowledge, there are no interactions with colloidal silver.

On the contrary, beneficial effects have been observed when conventional antibiotics are taken in combination with silver, as demonstrated by a study published in 2013.

We recommend storing it in a dark place at room temperature: a medicine box is perfect. For the gel, remember to replace the transparent cap to avoid oxidation.

In countries where colloidal silver is considered a dietary supplement, take 10 ml per day internally or spray externally 3 times per day. There is a full page on this subject here. 

The antiseptic action of colloidal silver can be explained in at least 3 ways. All three explanations are tied to its ability to inactivate microbial DNA and proteins, without damaging the tissue: 

1. Disruption of the outer membrane proteins of pathogenic organisms
2. Inactivation of bacterial enzymes
3. Inhibition of bacterial reproduction by way of their DNA 

Humans have enjoyed the beneficial properties of silver for thousands of years. Today, it is used to fight infectious diseases (bacteria, fungi, viruses, parasites) and to strengthen the immune system.

Colloidal silver is an aqueous solution made up of purified water and silver.

Conductivity meters (TDS meters) are designed to measure the conductivity of the water, and they are therefore calibrated with a saline solution. However, silver has an electric potential two times lower than salt: to obtain an approximate estimate of the concentration of the silver solution, you must multiply the result provided by your TDS by two. 2 x 20 = 40 PPM. Furthermore, testers that measure up to 999 PPM have a margin of error of 2%, or 20 PPM. These devices are therefore somewhat unreliable. 

For qualitative results, you need to use a spectrophotometer instead of a basic meter for measuring dissolved solids, which was never intended to measure colloidal silver. 

You can find all of the analyses proving the concentration of KATHAROS 40 PPM solution here.

There is no need for dilution; you can use your solution as it is. KATHAROS product, although more concentrated, still contains an extremely small quantity of silver.

KATHAROS product has a PAO (Period After Opening) of 6 months: once the bottle has been opened, you have 6 months to use it. This recommendation is based on tests carried out by independent laboratories before the product was placed on the market. However, after internal tests that have been made, it is indicated that is completely effective after 6 months.

As long as the bottle has not been opened, it can be stored indefinitely. 

KATHAROS solution is stored in glass bottles to avoid any risk of dispersion. Furthermore, the glass bottles are amber-coloured to protect the product from UV rays and guarantee its purity.

KATHAROS solution is completely transparent, which reflects its quality. The smaller the particles, the more transparent and effective the solution. The colour of the gel can vary due to oxidation: the colour does not affect its effectiveness.

KATHAROS only uses purified water and silver in the production of their liquids. For the gel, a natural preservative and gelling agent is added.

Thanks to its production method, KATHAROS solution is made up of minute particles measuring 150 picometres (less than a nanometre), thereby guaranteeing a high level of effectiveness.

After reviewing the scientific literature, it was found that many researchers concluded that: the more concentrated the solution, the more effective it is. Based on this observation, KATHAROS worked for more than a year to produce the most concentrated colloidal silver solution possible via electrolysis: their tests, allowed them to consistently achieve a concentration of 40 PPM.

The claim that solutions over 10, 15 or 20 PPM are less effective has been flying around for a while. There is no scientific data to back up this theory.
