If you are among one of the many who enjoy the ease and convenience of using protein powders to refuel post workout, you’ve likely encountered your fair share of the dreaded clump.
No one enjoys a lumpy, clumpy protein powder, so why does this happen? There’s a few reasons but don’t worry. It can easily be avoided in most cases with just a few tricks.
Does Clumping Mean Protein Powder Has Gone Bad?
While it’s off putting, clumping in your protein powder does not necessarily mean it has gone bad. While it can be a sign that your protein powder is rancid, this is usually accompanied by other, more obvious signs, including foul smell and changes in color.
Always check the expiration date on your supplements to avoid consuming powders that have gone bad. If your protein powder has not reached its expiration date yet and does not have the above characteristics, it’s likely clumping for other reasons.
Some common reasons your protein powder may clump include improper storage (protein powders should be stored in a cool, dry place), improper blending (avoid using a spoon to stir), improper temperature of the liquid (protein powders mix poorly in very cold water), or the quality of the protein powder itself.
Does Protein Powder Expire?
Like all supplements and food products, protein powder does expire. While it’s not usually harmful to consume past its listed expiration date, it will lose its potency.
Protein powders typically have a long shelf life but it’s still important to be aware of the expiration date which is required to be listed on the supplement label.
Protein powders typically have a shelf life between 1-2 years on average but this also depends on the presence of other ingredients in the product.
What's the Best Way to Store Protein Powder?
Protein powder is best stored in a cool, dry place. Any hint of moisture that it is exposed to will result in clumping and can render the product inefficient.
The best places to keep your protein powder are likely in a kitchen cabinet or drawer to keep it away from sunlight and nice and cool. Be sure to keep the product tightly sealed to prevent any moisture from leaking in, particularly if you live in a humid climate.
How to Avoid Clumps in My Protein Shake?
The best way to avoid clumps in your protein shake is to choose a high-quality protein powder and be sure to store it properly. Keep the lid on tight and store in your cabinet where it will stay cool.
When going to mix your protein powder, avoid using liquids that are too cold as this can make it more difficult for the product to disperse well.
Also use the proper blending method, which can include a blender bottle, a shaker cup, or even a milk frother. Avoiding trying to mix your protein powder with just a spoon.
What if I Don't Have a Blender and Only a Shaker Bottle?
While a blender will work best at evenly dispersing the protein powder for creamy results, a shaker bottle will work as well.
When using the shaker, be sure to use water that is room temperature versus ice cold as this will help mix the powder evenly. Most protein powders recommended letting your protein shake sit following use of a shaker cup to reduce foam.
Why Does Whey Isolate Get Foamy?
If you use a whey protein isolate supplement you may notice that your powder gets foamy. While this may be concerning, it is completely normal with this type of protein powder.
Whey isolate gets foamy because it easily entraps air, especially when stirred vigorously. You may notice a layer of foam at the top of your cup if vigorously shaking with a shaker to mix the powder with your liquid.
How to Avoid Foamy Whey Isolate Shakes?
You can lessen the foam from your whey protein isolate shakes by mixing your shake prior to your workout and letting it sit, mixing the protein powder in slowly and avoiding shaker cups, or by using room temperature or lukewarm liquid.
It also helps to use 100% whey isolate, such as our Clear Naked Whey, which has 20 grams of pure whey protein isolate versus those that have added ingredients. Use a shaker cup to mix your shake and let it sit to reduce the foam.
