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.
