Whey is one of the most popular protein powders on the market, especially among bodybuilders and anyone who practice weight training on a regular basis. Because whey protein is easily absorbed, it’s most typically utilized as a post-workout protein (particularly when supplementing with whey protein isolates).
When a protein is quickly absorbed, the body may instantly begin the process of muscle repair and regeneration. Whey protein also has a higher concentration of the BCAAs leucine, isoleucine, and valine. While all essential amino acids are necessary for muscle growth, leucine is the one that gets things started.
Whey protein powder has a shelf life of at least 18 months when maintained under normal circumstances, according to a 2016 research published in the Journal of Dairy Science titled “Physical and chemical changes in whey protein concentrate held at increased temperature and humidity.” 70°F and 35 percent humidity are considered standard circumstances.
This applies to the majority of kitchen pantries, cabinets, and closets. Researchers studied the physical parameters of two batches of whey protein concentrate stored in less-than-ideal circumstances to see how hot, humid environments impact the shelf life of protein powder.
Whey protein concentrates containing 34.9 grams of protein per 100 grams and 76.8 grams of protein per 100 grams were kept for up to 18 months in high humidity and high temperature conditions. The samples became yellow far sooner than they would under normal circumstances. Because of their alarming look, the whey protein held at 95°F was withdrawn from the research after a year.
The samples exhibited a shelf life of roughly nine months at 95°F when stored in sealed bags. Protein powders can spoil more sooner if they’re not kept cool and dry, or if their containers aren’t properly sealed, according to the researchers.
Other protein powders, such as pea protein, brown rice protein, and egg protein, are recommended in a similar way to whey protein. Keep your protein powder in a cold, dry location at a temperature that is as near to 70°F as feasible, such as the pantry or within a kitchen cabinet.
Here’s a short rundown of good storage options:
- Inside the pantry
- Inside a cabinet
- Placed in a drawer
- On a wall shelf where it will not be exposed to direct sunlight
- In a cupboard
Keep in mind that you want your protein powder to be room temperature or “cool,” not frozen or chilly. Protein powder should not be stored in the refrigerator or freezer because the repeated transition from hot to cold as the container is brought in and out might generate condensation, which can cause your protein powder to spoil before its expiration date.
Also, stay away from the extremes of the temperature range, such as warm or hot. You run the danger of spoiling or reducing the shelf life of your protein powder if you store it in a room that is normally warmer than 70°F, or in any region with excessive humidity or moisture.
You may keep your protein powder in a firmly sealed tub, pouch, or zip-lock bag for storage. If your protein powder comes in a pouch, you shouldn’t need to move it to a tub or canister because most companies construct their packaging with optimal storage in mind (or vice versa). Your protein powder should be good in its original packing as long as it is stored in reusable packaging that can be properly sealed and maintained in a dry, dark environment. If your protein powder comes in a tub, make sure the lid is snugly twisted on after each use; if it comes in a resealable bag, make sure it’s sealed airtight after each use. Heat and moisture are the main threats to your protein powder’s shelf life, so keep all packaging away from sunlight and water.
Whether you keep your protein powder in a cupboard or on a shelf in your pantry, it’s generally a good idea to put it front and center among your other items so you don’t forget about it. You don’t want to go through your cupboard and find a batch of protein powder that has passed its expiration date.
Do Protein Powders Actually Expire?
As previously stated, most protein powders have a shelf life of around 1.5 years when stored at normal temperatures (70°F and 35% humidity). If a protein has additives, the shelf life can be extended by up to two years.
Plant proteins maintain better than milk proteins like whey or casein because the absence of milk components reduces serious bacterial issues right away. However, virtually all protein powders, from whey to pea, are low-moisture foods, making them less susceptible to bacterial development (even if they aren’t dairy-free). You shouldn’t be concerned about dry food, such as protein powder, going bad as long as you eat it within a few years after purchase and keep it in perfect circumstances.
How To Tell When Protein Powders Go Bad?
Protein powder that has gone “bad,” like damaged foods, may typically show various indications, including:
- Rancid or sour smells
- Bitter taste
- Changes in color
- Wet lumps or clumping
Although the Food and Drug Administration (FDA) does not compel supplement manufacturers to include an expiration date on their labels, many high-quality brands do. They want their consumers to have reasonable expectations of the product’s quality. However, depending on how you kept your protein powder, it might go bad sooner than the expiration or “use by” date. That’s why, rather than focusing just on the date written on your goods, it’s more vital to pay attention to your storage circumstances, as well as how your powder looks and smells. If you open a protein powder bottle and it stinks, tastes, or is full of moist clumps, throw it away, regardless of the expiration date or the quantity of protein remaining.
Does A Protein Shake Need To Be Refrigerated?
Protein powders aren’t supposed to be kept in the fridge, but what about protein shakes? Many individuals prefer prepackaged protein drinks or manufacture protein shakes that aren’t consumed immediately. The protein powder itself does not need to be refrigerated, but it should be if it is blended into a drink or smoothie and not consumed immediately away.
Expiration dates and storage recommendations for protein powder apply only to the dry powder, not to a protein smoothie. When you combine protein powder with other foods, especially perishables like milk or vegetables, the powder’s expiration date no longer applies since food storage differs from dry protein powder storage.
You should eat your protein powder straight away or store it in the refrigerator if you mix it with your favorite drink, fruits, or vegetables. You may keep your protein shake in the fridge for up to two days.
If you leave the protein shake out in warm or hot weather for a few hours, you will not want to consume the contents. So, if you didn’t drink your protein shake right away or put it in the fridge, dump it and start again in a clean shaker.

How Long Does Whey Protein Last In The Fridge?
Whey protein should not be kept in the refrigerator because it is a dry powder. Condensation will form inside the container as a result of the temperature fluctuations involved in pulling it out to use it and then putting it back.
Unless you’ve blended it with fruits or other components that don’t last as long as whey protein, you may make a shake and keep it in the fridge for up to 48 hours. Before drinking, give it a good shake to separate the protein powder.
Whey protein-based baked items and other meals may be stored in the refrigerator for up to two weeks, just like any other sort of milk-based recipe.
How Long Does Whey Protein Last In The Freezer?
If you bring home considerably more whey protein powder than you can take in a reasonable length of time, one alternative is to put it in the freezer. However, it has no effect on the quality of your powder.
Dry whey protein won’t survive as long in the freezer as wet whey protein, but it won’t be destroyed unless you expose it to moisture. The largest threat to whey protein is condensation formed by the container, which is moved from cold to warm temperatures, much like in the refrigerator.
Whey protein may be stored without causing any damage when combined into a smoothie or another dish. It can last roughly as long as a milk product in terms of freshness.
Whey protein, according to most sources, may last 9-19 months if properly kept and protected from moisture, light, and heat. If you take care of it, it might survive even longer.
How To Store Whey Protein?
Maintaining the freshness of your whey protein requires proper storage. Over time, the quality of whey protein deteriorates. It is less likely to make you sick, but it does lose its effectiveness with time.
Whey protein should be stored in a dry, dark, and cold environment. Your pantry or closet is perfect. Protein powder is harmed by light, heat, and moisture. Keep the container securely closed to keep out air and moisture.
It is not required to keep whey protein in the refrigerator or freezer. Condensation may collect on the inside of the container, which the powder will absorb.
Whey protein should not be kept on top of the refrigerator. Whey protein cannot withstand the heat generated by your appliances. It will deteriorate in a hazardous manner.
How Do You Unfreeze A Protein Shake?
If you want to freeze whey protein, either dry or in a smoothie, you’ll need to know how to defrost it before drinking it.
The easiest way to defrost whey protein is to leave it in the fridge overnight. This can help to prevent condensation from forming, which can cause your protein powder to deteriorate fast.
If you’re thawing a frozen protein shake, you may utilize the defrost feature on your microwave. Keep in mind that you don’t want it to become too hot since you want it to stay chilly.
Whey protein, casein, and milk powder are all derived from dairy. Most dairy products you’re familiar with deteriorate rapidly. The dry environment, in which bacteria cannot thrive, distinguishes protein powder. Keep whey protein dry and cold, and it should last 9 to 19 months on average.
