Protein shake enthusiasts would be on top of their game, drinking their shakes immediately after mixing them and washing their shaker bottles before the protein residue can harden.

But, we’re all busy, and sometimes our lives don’t go according to plan.

Unfortunately, the longer those contents sit in your bottle, the harder they will be to clean.

Therefore, we are left with the following queries:

How Long Can A Protein Shake Last in The Fridge?

Are you constantly wondering if your fridge protein shake has gone wrong? Look no further because the answer is quite simple.

On average, a protein shake can last up to three days ( 72 hours ) in the fridge as long as it’s sealed and not left out at room temperature for extended periods.

However, some potential signs that your shake has gone lousy include discoloration or mold growth on the surface. And if the shake starts to taste or smell off, it’s time to toss it out.

So remember, when in doubt about the lifespan of your post-workout fuel, trust your senses and be on the safe side by chucking it out and grabbing a fresh one instead.

How Long Does Protein Shake Last At Room Temperature?

Depending on the type and amount of protein powder used and the room temperature, a protein shake can last approximately 2 hours.

However, if you want to err on the side of caution and protect your precious gains, it’s best to stick with the one-hour rule.

After all, nobody wants to suffer through a fuzzy protein shake when they could have just made a fresh one.

So next time you’re tempted to leave your shake out for a pre-workout, pick me up, think twice, and pop that baby in the fridge instead.

What to do if your protein shake goes bad?

Nobody wants to chug down a protein shake that smells like old cheese and tastes like sour milk.

But what should you do if your trusty shake goes rotten? First of all, don’t panic. If it’s only been a couple of days, give the container a sniff test before pouring a serving.

If it smells off but not too bad, try adding some fresh fruit or other flavorings to mask the taste. If it’s completely spoiled, it’s best to throw it out and make a new one.

But how can you prevent this from happening in the future? Ensure you’re storing your shakes in the fridge, and always check expiration dates before using them.

For those busy mornings on the go, consider investing in single-serving packets or reusable bottles that can easily be stored in a lunch box or gym bag.

Don’t let sour shakes ruin your gains – take these simple steps to keep them tasting fresh.
