Category: Storage & Shelf Life
Most protein bars are safe to eat 1-3 months past their "best by" date if stored properly. The date is about quality, not safety. However, check for off smells, discoloration, or unusual texture before eating.

Protein bar expiration dates are "best by" dates — they indicate peak quality, not safety. Most bars remain safe for 1-6 months past this date depending on ingredients and storage. Bars with nuts and oils degrade faster due to fat oxidation. Bars stored in cool, dry conditions last longer. Always inspect before eating — if it smells off, looks discolored, or has an unusual texture, discard it.
