How Long Is Homemade Colloidal Silver Good For?
Homemade colloidal silver can last for a long time if stored properly. The silver particles remain stable in the solution for a few months up to several years, depending on the quality of water used and the storage conditions. Colloidal silver should be stored in an amber or dark glass bottle, away from light, heat, and electromagnetic fields to prevent degradation. Testing the potency periodically with a TDS meter can help determine its efficacy over time.
