Tag: Expired protein shakes

Thanks to advanced aseptic pasteurization and special packaging, unopened fairlife Core Power protein shakes are shelf-stable for months, but they are not immortal. Like all dairy products, fairlife Core Power shakes expire and can spoil, especially after the seal is broken.

According to Premier Protein’s FAQ, a 'best before' date on their products indicates peak quality, not a strict safety deadline. This means it *might* be safe to drink Premier Protein shakes after the expiration date, but only if they have been stored correctly and show no signs of spoilage.
