Can I use Sovereign Silver Bio-Active Silver Hydrosol after the 3-year expiration date?

All Sovereign Silver products carry a 3-year expiration date, supported by evidence from stability studies. This means that even at the 3-year mark, a silver content analysis would still show a reading of at least 10 ppm (label claim). Over time, the concentration may decrease gradually as the silver adheres to (or adsorbs onto) the inside of the glass bottle or the surfaces of the closure system. It is always best to consume the product by (or before) the expiration date.
