How to stop stomach pain from protein shake?


Stomach pain after consuming a protein shake can be a common issue for some individuals. While protein shakes are generally considered a convenient and effective way to supplement protein intake, they can sometimes cause discomfort. In this article, we will explore several strategies to help alleviate or prevent stomach pain associated with protein shakes.

Possible Causes of Stomach Pain from Protein Shakes

There can be several reasons why protein shakes may cause stomach pain. It is essential to identify the potential causes to determine the appropriate solution. Here are a few possible reasons:

1. Lactose Intolerance: Some protein shakes contain lactose, a sugar found in milk. If you are lactose intolerant, consuming lactose-containing protein shakes can lead to digestive issues and stomach pain.

2. Low-Quality Protein: Protein powders of inferior quality may contain additives, fillers, or low-quality protein sources that can be harder to digest, resulting in stomach discomfort.

3. Allergies or Sensitivities: Some individuals may have allergies or sensitivities to specific protein sources, such as whey or soy. Consuming protein shakes made from these sources can cause stomach pain in such cases.

4. Excessive Protein Intake: Consuming an excessive amount of protein in a short period can overwhelm the digestive system, leading to stomach pain and discomfort.

Strategies to Alleviate Stomach Pain from Protein Shakes

Now that we have identified some possible causes, let’s explore strategies to alleviate stomach pain from protein shakes:

1. Opt for Lactose-Free Protein Shakes: If you are lactose intolerant, choose protein shakes that are specifically labeled as lactose-free or opt for plant-based protein powders, which are generally lactose-free.

2. Choose High-Quality Protein Powders: Select protein powders from reputable brands that prioritize quality. Look for products that undergo third-party testing to ensure purity and digestibility.

3. Experiment with Different Protein Sources: If you suspect an allergy or sensitivity to a particular protein source, try switching to a different protein powder. For example, if you have been using whey protein and experiencing stomach pain, consider trying a plant-based protein powder like pea or hemp.

4. Gradually Increase Protein Intake: If you are new to protein shakes or have recently increased your protein intake, it is essential to do so gradually. Give your body time to adjust by slowly increasing the amount of protein consumed over several days or weeks.

5. Ensure Proper Mixing: Improperly mixed protein shakes can lead to clumps that are harder to digest. Use a blender or shaker bottle to ensure thorough mixing and a smoother consistency.

6. Stay Hydrated: Drinking enough water throughout the day can aid digestion and prevent stomach discomfort. Make sure to consume an adequate amount of water alongside your protein shake.


Stomach pain from protein shakes can be a result of various factors, including lactose intolerance, low-quality protein, allergies or sensitivities, and excessive protein intake. By identifying the underlying cause and implementing appropriate strategies, such as opting for lactose-free protein shakes, choosing high-quality protein powders, and gradually increasing protein intake, you can alleviate or prevent stomach pain associated with protein shakes. Remember to consult with a healthcare professional if you experience persistent or severe stomach pain.
