How do I tell if protein powder is bad?

There are a few signs that indicate protein powder has gone bad and should no longer be used:

  1. Off odor: If the powder has a rancid, moldy, or otherwise unusual smell, it may be a sign that it has gone bad.
  2. Change in texture: If the powder has become clumpy, has a gritty texture, or has formed lumps, it may be a sign of spoilage.
  3. Discoloration: If the powder has changed color or has darkened, it may indicate that it is no longer fresh.
  4. Expiration date: Always check the expiration date on the package to ensure that the protein powder has not passed its shelf life.

It's important to store protein powder in a cool, dry place, and to keep the lid tightly closed to prevent contamination and spoilage. If you suspect that your protein powder has gone bad, it's best to discard it and purchase a fresh supply.
