For hundreds of years, silver has been shown to be a powerful, natural antibiotic and prevents against infection. We now know that it acts as a catalyst in disabling the enzyme that single-celled bacteria, viruses and fungi need for their oxygen metabolism.
The good news is that micro-organisms appear unable to adapt in the presence of silver particles the way they can with pharmaceutical antibiotics.
Especially important is that properly produced silver particles are harmless to higher life forms like humans, animals and plants.

We offer two kinds of colloidal silver and both are high quality and manufactured to produce the most effective kind of colloidal silver. One is our Ionic based silver, while the other is our Particulate based silver. True quality is based on a combination of PPM (parts per million) as well as particle size. Most colloidal manufacturers only list PPM. The effectiveness of the silver particles is based upon the total surface space of the particles. Many commercial brands will produce silver particles that are in the 100 nanometer to 1 micron range. QuantumSilver nanoparticles have the highest bioavailability, therefore gaining access to the site of action in the system more rapidly. Third party testing has shown that QuantumSilver has silver particles in the range of 2 to 10 nanometers in size, which could be as much as over 100 times the surface space as other colloidal silver products.
