Can protein powder cause digestive problems?
Protein powder can cause digestive problems.
Does protein powder upset your stomach?
Many protein powders are hard to digest, and if you experience digestive problems (bloating, diarrhea, etc.) after drinking a protein shake, you are not alone. Every day, thousands of Americans use protein powders that upset their stomach. Unfortunately, many of them assume that protein and indigestion go hand in hand, which is simply not true. Protein powder does not have to upset your stomach, and if it does, you are using the wrong protein powder.
Protein itself is not hard to digest, but many of the other ingredients in protein powder are. Moreover, the only way to understand why a protein powder is upsetting your stomach is to read the ingredient list. Reading the ingredient list is especially important if you suffer from a condition like Candidiasis, Crohn’s, diverticulitis, gastritis, gastroparesis, GERD, leaky gut, IBS, IBD, SIBO, or ulcerative colitis. Once you understand what is in your protein powder, it will immediately make sense why it is hard to digest. To help you get started, here are a few to the top protein powder ingredients to avoid.
Avoid food additives.
Most protein powders are full of food additives. Although not necessarily bad for you in small quantities, additives can add up quickly (especially if you drink a protein shake every day) and cause gastrointestinal (GI) side effects like bloating, constipation, diarrhea, gas, and stomach pain. This is because food additives are, generally speaking, hard to digest. They sit in your gut for longer than food should, which gives your gut bacteria more time to eat. As they eat, these bacteria produce gas, which causes bloating and stomach pain. Gas also slows colonic transit (the amount of time it takes food to travel through the colon) and can lead to constipation.
In the long term, food additives can disrupt regulatory pathways in the intestine, which can result in the development of inflammatory bowel disease (IBD) and systemic inflammatory disorders. Artificial sweeteners are among the most harmful additives in the long term as they alter the composition of your gut microbiota (the collection of microorganisms that help you digest food). This can lead to serious, chronic GI problems, widespread inflammation, and permanent damage to the gut microbiome. Some sweeteners, especially sugar alcohols like xylitol, are also poorly absorbed by the gut (meaning they feed those hungry gut bacteria) and cause diarrhea because they draw water into your intestine. Now you finally have something to blame for those post-protein shake trips to the bathroom!
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 that will not cause digestive issues, 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 and casein, which are byproducts of cheese and yogurt production, 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 isolate (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 almonds. Egg whites are simply pasteurized and dried before becoming protein powder. Almonds are just roasted, pressed, and ground. Minimally-processed ingredients like these are an easy to digest, gut-friendly alternative to protein concentrates and isolates.
Unless you have a sensitivity or allergy to eggs, egg white protein is the best protein for your gut. 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 almond protein powder. Unlike protein concentrates or isolates, almonds contain lots of healthy fats, fiber, and other nutrients like calcium and vitamin E. We prefer almonds to other minimally-processed plant protein sources because they are more gut-friendly. Research suggests that almonds can improve the diversity and composition of the gut microbiome. Research also suggests that almonds possess prebiotic properties, meaning they stimulate the growth of healthy bacteria in the gut.
“I just finished my first bag and ordered 2 more! I Iove this stuff! I have IBS and every protein powder hurts my stomach…except drink wholesome!”
Why drink wholesome?
Our protein powders are additive-free, dairy-free, and made with real foods, not protein isolates. They are perfect for people with gut issues and sensitive stomachs, as well as for people just looking to boost their protein intake without the processing and added junk.
Sick of protein shake digestion problems? If you suffer from Candidiasis, Crohn’s, diverticulitis, gastritis, gastroparesis, GERD, leaky gut, IBS, IBD, SIBO, or ulcerative colitis, switch to drink wholesome. It is made with simple, easy to digest ingredients. Order samples to see for yourself.
