From the brand

It was in October 2014 that Jean, our founder, heard about colloidal silver for the first time. Taken aback, he discovers its incredible merits and wonders why this solution is so little known to the general public. It was in the face of this observation that the Katharos Institute was born and it has a clear mission: to make the world aware of the extraordinary qualities of this thousand-year-old product!

What makes our company unique?

The feeling of having a mission: We are fortunate to be able to offer you this product and are aware of this great responsibility.

Why we love what we do?

We love colloidal silver and the impact it has on you. The whole team carefully reads each of your opinions and that gives us the energy to serve you on a daily basis.

Why do we only make colloidal silver?

We are convinced that manufacturing with care in France only colloidal silver is the best proof of quality

A complete range.

Gel, liquid, small format, economical format … Our colloidal silver is available in 7 different packaging.

Is the bottle made of glass?

Yes. Although more expensive and fragile, we chose glass to maintain the purity of the solution. No compromise on quality!

What is the expiration date?

You can store colloidal silver for 30 months without opening it. Once opened, you have 16 months to use it.

Where can I find the Ebook?

Upon your purchase, you will receive an email within 3 days including your Ebook. You can also download it from the QR code on the packaging or label.

MORE CONCENTRATED FOR INCREASED EFFECTIVENESS After more than a year of research, we have accomplished what few others have achieved: Producing concentrated colloidal silver at 40 PPM via low-voltage electrolysis. This is of paramount importance since a more concentrated solution is more effective, as demonstrated by a peer-reviewed scientific study published in 2010 in the journal Applied Microbiology and Biotechnology.
MORE THAN JUST COLLOIDAL SILVER Our mission as a team is to impart our love and knowledge of colloidal silver to you. The free E-book included with every purchase gives you an in-depth insight into the incredible world of Colloidal silver and how it can improve your life. The best part? All orders arrive with a beautiful 30ml spray to fill to conveniently take your colloidal silver with you anywhere. A handy measuring cup included makes sure you always pour the correct amount.
WATER OF EXTREME PURITY We chose the purest water available – Type 1 UltraPure Water. It is used for the most critical laboratory operations, as in molecular biology. It must be pointed out that most colloidal silver solutions contain type 2 or 3 ultrapure water, which can contain up to 100 times more bacteria than type 1 ultrapure water! In order to maintain this high level of purity, we have chosen to use amber glass bottles.
SOLUTION CERTIFIED BY 3 INDEPENDENT LABORATORIES Many companies have abused consumers' trust and are quick to have less PPM than advertised. In order to demonstrate our earnestness, we have published all the analyses that certify our concentration at 40 PPM as well as our use of type 1 ultrapure water, on our website. We are the only company in the industry to share the results of our product analyses with our users.
WE ARE SPECIALISTS AND PRODUCE OUR SOLUTION OURSELVES Many companies do not mind subcontracting the production of their colloidal silver at the expense of quality. Often, these same companies also offer dozens of other outsourced products. We are proud to specialise in colloidal silver – in fact, we have been proudly producing, packaging and selling our solution ourselves for many years.
