Can Protein Powder Go Out Of Date

If you have ever entered a protein shop you probably have seen Costco-sized protein powder tubs everywhere. Their size can make it difficult to consume them before the date stamped on the side, which raises the question: Will protein powder actually expire?

Does Protein Powder Expire?

The shelf life of most protein powders is 12 to 18 months, which is occasionally made possible by the addition of preservatives. Protein powder can go bad even if, when stored properly, it does not go bad like meats and fresh food. Protein powder has an expiry date, which is marked on the container just like any other packaged commodity.

There are three different ways that expiration dates can appear on protein powder containers:

  • Use by: Consumers can look at this date as the date on which the product needs to be completely consumed. It is more concerned with quality over safety, although both are a factor.
  • Best by: This date is when a product should be consumed due to both safety and quality.
  • Sell by: Stores are concerned with the sell by date which indicates to them when the product should be sold or removed because typically, a product only has a third of its shelf-life left.

Since protein powders are all dry powders, their shelf life may vary, but they are less likely to actually spoil than other foodstuffs. Even protein powder, though, has a shelf life. In general, bacteria, fungi, oxygen, heat, and moisture cause food to genuinely go bad. Your container of protein may last months past the indicated expiration date if you can prevent those five items from entering the protein container by keeping it well sealed and stored in a cool, dry location.

Ways to Keep Your Protein Powder Fresh Longer

Follow these four storage suggestions to preserve the freshness of half a container of your valuable protein and prevent waste:

  • Protein powder should always be kept in the original container. The packaging is dark or opaque to shield the ingredients from light.
  • Store the protein container in a cool, dry location, such as a pantry or cabinet.
  • Protein powder shouldn’t be kept on top of a refrigerator. Its shelf life will be shortened there due to the mechanical heat and humidity.
  • Make careful to always use a dry spoon or scoop. Adding water to the container might encourage the growth of mold, which subsequently encourages the growth of germs.


Popular dietary supplements in the form of dairy protein powders or vegan protein powders are derived from both animals and plant sources respectfully.

Many protein powder makers specify an expiration date of two years after production even though research indicates that protein has a shelf life of 9 to 19 months. This is probably made feasible by additives that enhance shelf life.

If your protein doesn’t have a rotten smell, unpleasant taste, changes in color, or clumping, eating it soon after its expiration date is probably safe. But if you notice any of these issues in your protein powder, it is essential to replace your tub immediately.
