The shelf life of this true colloidal Silver can be several years unopened. The average nanoparticle size is 2 Silver atoms with about 0.28 nanometers in size. There is no true colloidal Silver product with smaller Silver nanoparticles as we have inspected them all.

No (0.00%) chemicals are found in this product – only 99.99+% pure Silver nanoparticles colloidally suspended in pure distilled water. No other ingredients – especially no preservatives or stabilizers as found in other colloidal Silver products.


If allowed to freeze, all of the Silver nanoparticles will no longer be colloidally suspended and afterward the colloidal suspension may collapse resulting in a loss of color as the Silver nanoparticles will have fallen to the bottom of the bottle, leaving only clear water.

WARNING: Avoid contact with this product if allergic to Silver.
