Colloidal Silver Shelf Life

Hi Utopia,
How long generally do you think your silver is good for? I want to purchase 9 bottles but I'm wondering if we don't use it all for a year or so will those bottles still be good?

Hi Michelle,
Colloidal Silver generally keeps better in larger volumes, so we don’t recommend the 8 oz. for long term storage as it is more susceptible to cold, which can cause the particle agglomeration and fallout. Volumes such as 1 gallon and 5 gallons if unopened and kept in an environment that isn’t too cold, will last indefinitely. We have 5 gallons in storage than were below sellable PPM for 7+ years with no visible changes.
