How long can a protein shake sit in the fridge?

In this brief guide, we will answer the question, “how long can a protein shake sit in the fridge?” with an in-depth analysis of how long a protein shake can sit in the fridge. Moreover, we are going to discuss when a protein shake is mixed, and how long it lasts. 

How long can a protein shake sit in the fridge?

If properly stored in an airtight container or bottle in the fridge at or below 40 degrees Fahrenheit, a homemade protein shake will last for around 72 hours.

So, if you’re going to utilize your protein shake within a few days, you should keep it at 40 degrees or lower. Bacterial growth is accelerated between the temperatures of 40 and 140 degrees Fahrenheit, therefore it’s best to keep your protein shake at a lower temperature to keep it fresh for as long as possible.

As a result, the cool temperature of the fridge will slow the growth of bacteria, extending the shelf life of your protein shake.

It’s worth noting that a chilled protein shake can separate into layers, so reblending it before drinking is recommended.

At room temperature, how long can a protein drink last?

When kept at room temperature, a protein shake will survive for around 2 hours.

Because bacterial development occurs more quickly between the temperatures of 40 and 140 degrees Fahrenheit, protein shakes left out for more than 2 hours should be discarded.

Furthermore, if the ambient temperature is about 90 degrees Fahrenheit, the rotting process is accelerated, and protein shakes left out in the open for more than an hour at 90 degrees Fahrenheit should be discarded.

How Long Can a Protein Shake Be Stored in the Fridge?

The greatest period of time a refrigerated protein shake can be consumed is 72 hours. If you leave it any longer, the whey protein will start to produce deadly bacteria. Any other local food (fruits and vegetables) will also begin to spoil. Protein smoothies created with milk, water, or other non-dairy liquids fall into this category.

  • A protein shake can be stored in the refrigerator for up to seven days.
  • Drink your protein shake no more than 12 hours after it’s been in the fridge for the finest flavor.

Drink the protein shake no more than 12 hours after it’s been in the fridge for the finest flavor. Local food can begin to change in flavor and consistency after this stage.

At room temperature, how long does a protein shake last?

In just over 2 hours, a protein drink left at ambient temperature will deteriorate. The shake’s protein content, as well as any dairy items, will begin to spoil. 

Not only will the flavor of the shake change, but it will also raise your chances of getting an upset stomach. This is true of whey protein powder-based shakes as well as plant-based protein-based smoothies.

What Are the Signs That Your Protein Shake Is Bad?

The stench is the most common symptom that a protein shake has gone bad. As the protein degrades, the shake will develop a foul odor. If your shake does not smell the same as it did when it was originally combined, toss it away, properly wipe the cup, and start over.

  • The stench is rotten and spoiled.
  • A taste that is bitter or odd in some way.
  • The texture is slimy.
  • Color that is darker or lighter than when it was first blended.

A bitter flavor, a slimy feel when you drink it, and a change in coloring and consistency are all symptoms that a protein shake has gone bad.

What Happens If You Drink a Malfunctioning Protein Shake?

Drinking a protein shake almost always results in an upset stomach and diarrhea. This can be moderate in some circumstances, but it can also be fairly severe in others. Drink fresh protein drinks and examine any chilled protein shakes before taking your first sip to avoid this.

The most common side effects include stomach upset and diarrhea.

Food poisoning from rotten protein drinks might result in vomiting.

Keep in mind that protein drinks containing spinach or other vegetables can harbor salmonella, a germ that can cause food poisoning. Food poisoning from a bad protein drink can induce nausea, vomiting, and even death.

When a protein shake is mixed, how long does it last?

The contents in your protein shake, as well as how you store it, determine how long it will last. The following is a quick guide to protein shake storage:

  • The maximum time a protein smoothie can be properly refrigerated is 72 hours.
  • A chilled protein shake containing fresh ingredients can last up to 12 hours before it starts to taste notably bad.
  • 2 hours is the maximum amount of time a protein shake can be left at room temperature safely.

To avoid being ill as a result of a terrible shake, follow these instructions. You’ll obtain the best-tasting, safest beverage by drinking fresh protein shakes. However, putting your shake in the refrigerator for a day or two won’t hurt it.
