Can Protein Shake Get Spoiled?

Protein shakes are a convenient and easy way to get the nutrients your body needs, but they can also go bad if they’re not stored properly. Here’s what you need to know about how long protein shakes last and when they start to spoil. Most protein shakes will last for 2-3 days in the fridge after being opened, but there are a few things that can make them go bad sooner.

If your shake has any dairy in it, it will only last for 1-2 days due to the milk spoiling quickly. If your shake has fruit or vegetables in it, those can also start to spoil more quickly. Finally, if your shake has been sitting out at room temperature, it will only last for 1-2 hours before going bad.

So how can you tell if a protein shake has gone bad? The easiest way is to smell it – if it smells sour or off, then it’s time to toss it out. You may also see some separation of the liquid and solid ingredients, or notice that the color has changed.

If you see any of these signs, it’s best to err on the side of caution and throw the shake out. Protein shakes are a great way to fuel your body, but be sure to keep an eye on them so they don’t go bad!
