How long can you store protein powder?
Good news! The “expiration date” on your protein powder is a quality date, not a safety date. This means your protein has a longer shelf life than indicated on the package. How long? Even months after date. Yup, totally safe ánd just as effective. The shelf life can vary depending on the ingredients and storage conditions. For example, you can store plant-based protein powder much longer than cow’s milk-based protein (whey and casein). Generally, it’s safe to use it up to 6-24 months after the production date if stored properly.
How do you store protein powder? – 6 tips
To make your protein powder last as long as possible (and thus past its expiration date), it is crucial that you:
- Original packaging. Preferably store the protein powder in its original packaging. In any case, do not empty the bag into those pretty clear storage jars. The powder is otherwise not protected from (sun) light;
- Cool, dry and dark. Store the bag in a cool, dry place away from direct sunlight and moisture
- Heat-Free. Do not store bag on your microwave, Airfryer, refrigerator or next to the stove. These devices give off heat.
- Not refrigerated. Do not store your bag of protein powder in the refrigerator or freezer. This place is damp.
- Dry measuring scoop. Always make sure the scoop or measuring spoon is dry before use. Moisture can lead to bacterial growth.
- Airtight. Make sure the container is tightly closed after each use. If the bag no longer seals properly, consider placing the bag in an airtight container for extra protection.
Spoiled? How do you know if protein powder has gone bad?
Use your nose, eyes and mouth to determine if your protein powder is still good.
If the fats in the dry powder have gone rancid, you can smell this: sour and musty.
Also, watch for lumps, discoloration and changes in taste. Don’t worry, you can safely taste without getting sick!
