Does protein powder make your stool hard?
Can protein powder make your stool hard?
Although a common side effect of protein powder is diarrhea, many people report that protein powder causes constipation and hard stools. Hard stools are the result of your colon absorbing too much water, which happens when food passes too slowly through your digestive system. Consuming protein powder can make your stools hard and difficult to pass because they are hard to digest, and therefore take a long time to move through your gut. If you want a protein powder that does not make it hard to poop, here are a few ingredients to avoid.
Avoid food additives.
Most protein powders are full of food additives. Although they are not necessarily bad for you in small quantities, food additives can add up quickly, especially if you drink a protein shake every day. At higher quantities, food additives can cause gastrointestinal (GI) side effects.
Many food additives are hard to digest and sit in your gut for longer than they should. This gives your gut bacteria more time to ferment (eat), and as they eat, these bacteria produce gas, which causes bloating, cramps, and nausea.
Gas also slows colonic transit (the amount of time it takes food to travel through the colon). This can lead to constipation and hard stools. Exactly why gas makes it hard for food to pass is a mystery, but one theory is that it reduces intestinal motility (the movement of muscles in the gut).
Keep an eye out for artificial sweeteners too. Artificial sweeteners are poorly absorbed by the gut, which means that they feed your hungry gut bacteria. They also alter the composition of your gut microbiota (the collection of microorganisms that help you digest food). This can lead to serious GI problems and widespread inflammation.
Here is a list of the most common food additives in protein powder:
acacia gum, acesulfame potassium, artificial flavors, aspartame, carrageenan, cellulose gum, dextrin, dextrose, erythritol, gellan gum, guar gum, gum arabic, inulin, locust bean gum, “natural” flavors*, maltodextrin, rice syrup solids, soy lecithin, silica, sucralose, sunflower lecithin, xanthan gum, xylitol
When it comes to identifying food additives, go with your gut. 😉 As a rule of thumb, they are the ingredients that you cannot pronounce. Food additives are not the only thing to look out for when buying protein powder, however. There are several other ingredients that can upset your stomach.

*This is the actual ingredient list of one of the best-selling protein powders in the United States.
Dairy-based proteins like whey can casein are byproducts of cheese and yogurt production. They are known to cause digestive issues, especially for people with lactose intolerance and irritable bowel syndrome (IBS). Over one in three Americans are lactose intolerant, and the prevalence of IBS is somewhere between 10 and 15 percent in the United States. It follows that you may be lactose intolerant or have IBS and not even know it.
Irritable bowel syndrome (IBS) is a poorly understood condition, and it is unclear why dairy triggers symptoms. Lactose intolerance, on the other hand, is clearly understood. People with lactose intolerance are unable to fully digest lactose, the sugar in dairy. As you just learned, partially digested food feeds the bacteria in your gut, which produce gas.
Avoid protein concentrates and isolates.
Finding an additive-free, dairy-free protein powder is hard. Finding an additive-free, dairy-free protein powder made with real foods is next to impossible. Why? Most protein powders are made with protein concentrates and isolates, foods stripped of everything but the protein. They are listed on the ingredient list as “pea protein,” for example, as opposed to “peas.”
We will not go into the details, but protein concentrates and isolates undergo heavy mechanical and chemical processing before becoming protein powder. Sometimes, manufacturers use chemical solvents like hexane to separate the protein from the food. This means that what you end up putting into your body looks nothing like real food.
The potential problem here is that your gut might not know what to do with ingredients like these. Your gut prefers the real thing, not some heavily-processed imitation, so protein concentrates and isolates might be hard to digest for people with sensitive stomachs.
Instead of protein concentrates or isolates, we use egg whites and chickpeas. Egg whites are simply broken, pasteurized, and dried before becoming protein powder. Chickpeas are just dried and ground. Minimally-processed ingredients like these are easy to digest and a stomach-friendly alternative to protein concentrates and isolates.
Unless you have a sensitivity or allergy to eggs, egg white protein is the best protein for people with sensitive stomachs. Egg whites are low in fiber, low-FODMAP, and have the highest protein digestibility-corrected amino acid score (PDCAAS) of any whole food. Our customers have experienced fewer digestive issues with egg white protein than with any other type of protein.
If you cannot eat eggs, try our chickpea protein powder. We like chickpeas because, compared to other plant protein sources, they are high in soluble fiber. Unlike insoluble fiber, which can have a laxative effect, soluble fiber increases in size as it moves through your digestive tract. This can help make your bowel movements easier and more regular.
