However, because they are sealed in their wrappers and not exposed to air or light, they can last for a long time without losing their flavor. The average shelf life for Life Savers is two years, but they have been known to last much longer. There have been reports of people finding Life Savers that are decades old and still taste fresh. So if you come across an old pack of Life Savers, don't be afraid to give them a try!
