FAQ

What is Ultra Silver?

Ultra Silver is a highly concentrated colloidal silver product made with .9999 fine silver and purified water.

We offer four concentrations:

500 PPM
1,000 PPM
5,000 PPM
10,000 PPM

Each concentration is available in multiple bottle sizes.

What does PPM mean?

PPM means parts per million. For colloidal silver, it describes the concentration of silver in the product.

For example, a 1,000 PPM product contains a higher concentration of silver than a 500 PPM product.

See our Colloidal Silver Concentration page for a more detailed explanation.

Why is Ultra Silver dark in color?

The amber-to-dark-brown appearance is a characteristic of our concentrated colloidal silver.

The color generally becomes darker as concentration increases. A concentrated colloidal product can therefore look very different from the clear or nearly clear ionic silver solutions commonly sold at much lower concentrations.

Is Ultra Silver independently tested?

Yes. We use independent laboratory testing to verify important characteristics of our products, including silver concentration.

Laboratory documentation is available to customers who would like additional information about our products.

What is the difference between colloidal silver and ionic silver?

The terms are sometimes used interchangeably in marketing, but they don't describe exactly the same thing.

Colloidal silver contains microscopic particles of silver suspended in a liquid. Ionic silver primarily contains dissolved silver ions.

For a more detailed explanation, see Colloidal Silver and Ionic Silver.

Why sell such high concentrations?

Ultra Silver specializes in concentrated products. Higher concentrations allow a substantial amount of silver to be supplied in a relatively small volume.

Our products range from 500 PPM through 10,000 PPM so customers can choose the concentration and bottle size appropriate for their intended non-medical use.
