What are the dosage recommendations for colloidal silver?

We have been​ contacted by the "Trading Standards and Environmental Health" department that notified us regarding the legislation surrounding colloidal silver.

Colloidal silver is not considered a dietary supplement as it does not appear in the EU list of minerals in the food supplementation legislation (2002/46/EC) : no health claims can be made regarding colloidal silver.

Though, the sale of colloidal silver in the EU is not permitted as a dietary supplement, it is authorized as a cosmetic product.

Therefore, colloidal silver can only be used externally : we do recommend to use it at least 3 times a day externally and letting it dry naturally.

Being a cosmetic product, Institut Katharos does not recommend ingesting colloidal silver.
