There is considerable discussion and controversy regarding whether ionic
silver or particulate (colloidal) silver is more efficacious. This
has been discussed on the silver-list
by many of the members; some of them having chemistry and/or medical
backgrounds. It is claimed by
colloids are more effective at killing pathogens. Their product is
about 90% colloidal while most ionic/colloidal silver is typically 75-95%
ionic. They claim that ionic silver is converted to silver
chloride in the stomach by coming in contact with hydrochloric acid,
thereby becoming ineffective.
Natural Immunogenics, manufacturer of Argentyn 23 claims the
ionic portion is more effective at killing pathogens. Their product
is about 95% ionic. In order to resolve the dispute Natural
Immunogenics performed kill studies using a controlled comparison
that diluted both MesoSilver and Argentyn 23 with hydrochloric acid to
neutralize the ions in MesoSilver. Then the two were diluted to 20
PPM each so the comparison would have validity. They
then combined the remaining fractions of Mesosilver and Argentyn with two strains of Staphylococcus Aureus.
The dilutions were placed on petri plates and graded as to their
effectiveness in killing the pathogens.
Please see the test results
Look near the bottom right side of the report for the in vitro kill rates. This should resolve the issue. It seems clear the
ionic portion is more effective at killing pathogens.

It should be noted that the silver
water produced with SilverGen generators is approximately 85-98+% ionic and
the balance is colloidal. So, no matter who you think is right, the water contains enough
of each form of silver to be effective.
We believe the ionic form of silver is
the best for killing pathogens, stem cell regeneration and also the form
that causes cancer cells to dedifferentiate. See
