Can Protein Shakes Hurt Your Stomach?

If you’re working out hard, you might be tempted to turn to protein shakes for help in building muscle. But while they can be a convenient way to get extra protein, they can also cause stomach problems. Protein shakes can hurt your stomach if you drink them on an empty stomach, drink them too fast, or don’t chew them well enough.

They can also cause problems if you have a sensitivity or allergy to one of the ingredients. If you’re having trouble with protein shakes, try drinking them slower, chewing them more thoroughly, or eating something before you drink them.

Stomach Issues with Protein Powders

If you’re like most people, you probably think of protein shakes as a healthy way to get the nutrients your body needs. But what you may not know is that protein shakes can actually hurt your stomach. Protein shakes are made with powdered milk or whey, and these dairy products can be hard for some people to digest.

If you have trouble digesting lactose, the sugar in milk, then you may experience gas, bloating, and other uncomfortable symptoms after drinking a protein shake. Another problem with protein shakes is that they often contain added sugars and other ingredients that can upset your stomach. So if you’re feeling bloated or gassy after drinking a protein shake, it’s probably because of the ingredients, not the protein itself.

So what’s the bottom line? Protein shakes can be healthy for some people, but they’re not right for everyone. If you have trouble digesting lactose or find that sugary protein shakes make your stomach feel worse, then it’s best to avoid them altogether.

Can Protein Cause Stomach Problems

If you’re like most people, you probably think of protein as something that’s good for you. After all, it’s an essential nutrient that helps build and repair muscle tissue, and it can also help you lose weight. But what you may not know is that protein can also cause stomach problems.

That’s because protein is a large molecule that takes longer to digest than other nutrients. When it breaks down in your stomach, it can produce acids that can irritate your digestive system. This can lead to symptoms like heartburn, indigestion, and bloating.

So if you’re having stomach problems, you may want to cut back on the amount of protein you’re eating. And if you’re taking a supplement like whey protein, be sure to drink plenty of water with it to help flush out your system.

Why Do I Feel Sick After Drinking a Protein Shake?

If you’re wondering why you feel sick after drinking a protein shake, it could be because of the ingredients. Some protein shakes contain dairy or soy, which can cause bloating and gas. Other common ingredients in protein shakes, such as caffeine or sugar, can also upset your stomach.

If you have trouble digesting lactose (the sugar in milk), consider using a plant-based protein powder instead of one that contains whey or casein from milk. If you’re still having stomach issues after switching to a different type of protein powder, it’s best to speak with a doctor or registered dietitian to figure out what’s causing your discomfort.

Can Protein Cause Your Stomach to Hurt?

There are a few different ways that protein can cause stomach pain. The first is if you have a sensitivity or intolerance to a certain type of protein. This can cause digestive symptoms like bloating, gas, and diarrhea.

If you think you may be sensitive to a certain type of protein, try eliminating it from your diet for a week or two to see if your symptoms improve. Another way protein can cause stomach pain is if you eat too much of it at once. Eating a large amount of any food can lead to indigestion and stomach pain, but protein is especially hard for the body to digest in large quantities.

So if you overeat protein-rich foods like meats or cheeses, you’re more likely to end up with an upset stomach. Finally, some types of proteins can be contaminated with harmful bacteria that can cause food poisoning. This is especially true of poultry and eggs which often carry salmonella bacteria.

If these bacteria aren’t cooked properly, they can infect anyone who eats the contaminated food and lead to severe stomach cramps, vomiting, and diarrhea.

So while protein itself isn’t necessarily bad for your stomach, there are some circumstances where it can lead to discomfort. If you think you may be sensitive to certain types of proteins or if you tend to overeat protein-rich foods, it’s best to talk to your doctor or dietitian about how to best incorporate this nutrient into your diet without causing gastrointestinal distress.

Is Protein Powder Hard on Your Stomach?

No definitive answer exists as to whether protein powder is hard on your stomach. However, some people may experience digestive discomfort after consuming protein powders, particularly whey-based powders. This is likely due to the fact that whey is a dairy product and contains lactose, which can be difficult for some people to digest.

Additionally, protein powders often contain other ingredients that may irritate the stomach, such as artificial sweeteners, flavours and colours. If you find that protein powder upsets your stomach, try switching to a plant-based powder or taking it with food. You may also want to talk to your doctor or a registered dietitian about which type of protein powder would be best for you.


Protein shakes are a great way to get extra protein into your diet, but they can sometimes cause stomach issues. If you’re having trouble with protein shakes making your stomach hurt, there are a few things you can do to help. First, try drinking your shake with a meal instead of on an empty stomach.

This will help your body digest the shake better. Second, make sure you’re drinking plenty of water throughout the day to keep your digestive system moving smoothly. Finally, if you’re still having trouble, try a different type or brand of protein powder.

There are many different types available, so finding one that works for you may just take some trial and error.
