What is the best SIBO-friendly protein powder?
Written by Jack Schrupp and reviewed by Ella McGonagle, M.S. Nutrition
drink wholesome is the best SIBO-friendly protein powder. It is additive-free, dairy-free, and made with real foods, not protein isolates – 99% of supplements fail to meet at least one of these criteria. This makes it 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. If you suffer from SIBO, or any other digestive disease, order samples to see if our protein powder is right for you.

What is SIBO?
Small intestinal bacterial overgrowth (SIBO) occurs when there is an overgrowth of bacteria in the small intestine, particularly of types of bacteria that normally grow in other parts of the gut. This overgrowth can cause stomach pain and diarrhea, and can lead to malnutrition and weight loss in severe cases. Although SIBO remains a poorly understood disease, it is associated with several chronic conditions including irritable bowel syndrome (IBS), Crohn’s disease, and gastroesophageal reflux disease (GERD). It can also be a complication of abdominal surgery.
The goals of SIBO treatment are threefold: 1) correct the underlying cause; 2) provide nutritional support, if necessary; and 3) treat the overgrowth. The most common treatment for SIBO is antibiotics, which can help decrease the number of bacteria in the small intestine. Antibiotics will not address the underlying issue that caused SIBO in the first place, however, which is why antibiotics are often paired with changes to diet.
What is the SIBO diet?
The SIBO diet is a temporary elimination diet used to help people determine which foods are problematic and cause symptoms. It involves eliminating certain carbohydrates, specifically high-FODMAP foods, to starve gut bacteria (bacteria eat carbohydrates). FODMAPs are short-chain carbohydrates that are indigestible or poorly absorbed by certain people. The SIBO diet has three steps. First, you stop eating high FODMAP foods. Next, you slowly reintroduce these foods to determine which ones are problematic. Finally, once you have identified the foods that cause symptoms, you avoid or limit them.
Although the SIBO diet is characterized by elimination, there are a few key ingredients, and one of them is protein. Eating lots of protein is important because SIBO can impair your ability to absorb nutrients from food. Basically, the excess bacteria in your small intestine break down your bile salts, which are used to digest fats and protein. The result is an impaired ability to digest and absorb these nutrients, which can lead to nutritional deficiencies and impact your overall health.
Can you have protein powder on the SIBO diet?
You should aim to eat 1-2 grams of protein per kilogram of body weight per day, and to get as much protein as you can from normal food. Getting enough protein this way can be challenging for some people, however, which is where protein supplements can help. There are two types of protein supplements: ready-to-drink (store-bought) protein shakes, and protein shakes made with protein powder. In order to make a protein shake with protein powder, you have to mix the powder with milk or water. This requires a blender or a shaker bottle, and a little extra time and effort. Some people, prioritizing convenience, prefer to buy ready-to-drink protein shakes, but if they knew what they were drinking, they would probably vomit.
Ready-to-drink protein shakes are full of emulsifiers, stabilizers, thickeners, sweeteners, and flavors. Ingredients like these improve characteristics like taste, texture, and shelf stability, but can cause uncomfortable side effects and long-term gut damage (more about this soon). This is why I recommend that you make your own SIBO-friendly protein shakes with protein powder. That said, not all protein powders are created equal, and many contain the same additives found in ready-to-drink protein shakes!
Why drink wholesome?
drink wholesome is additive-free.
One of the reasons why we make SIBO-friendly protein powder is that we do not use food additives. Most protein powders, on the other hand, 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 hard to digest, and 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.
When buying protein powder for SIBO, one ingredient to avoid in particular is artificial sweeteners. Artificial sweeteners are among the most harmful food 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 for SIBO, however. There are several other ingredients that can upset your stomach.
Protein Matrix Comprised of (Whey Protein Concentrate, Whey Protein Isolate, Calcium Caseinate, Micellar Casein, Milk Protein Isolate, Egg Albumen, Glutamine Peptides), Polydextrose, Sunflower Creamer (Sunflower Oil, Corn Syrup Solids, Sodium Caseinate, Mono- and Diglycerides, Dipotassium Phosphate, Tricalcium Phosphate, Soy Lecithin, Tocopherols), Natural and Artificial Flavor, MCT Powder (Medium Chain Triglycerides, Nonfat Dry Milk, Disodium Phosphate, Silicon Dioxide), Lecithin, Cellulose Gum, Salt, Yellow 5, Sucralose, Acesulfame Potassium, Papain, Bromelain.

drink wholesome is dairy-free.
Another reason why we make SIBO-friendly protein powder is that we do not use dairy-based proteins. Many protein powders are made with whey and casein, which are byproducts of cheese and yogurt production, and 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.
drink wholesome is made with real foods.
A final reason why we make SIBO-friendly protein powder is that we do not use protein isolates. Most protein powders, on the contrary, are made with protein concentrates and/or isolates, foods stripped of everything but the protein. They are listed on the ingredient list as “pea protein” and “whey protein” as opposed to “peas” and “whey.” I 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.
If you think about it, your gut was designed to digest naturally occurring foods, not laboratory formulated imitations, so if you feed it anything but real food, it might get upset. The long term implications of eating processed foods are still not well understood, but more and more research is finding that it can alter the composition of your gut microbiota, and lead to permanent damage to the gut microbiome. It is therefore in your best interest to avoid protein powders made with protein concentrates and isolates.
Instead of protein concentrates or isolates, we make SIBO-friendly protein powder with 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, naturally alkaline, 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 possess prebiotic properties and can improve the diversity and composition of the gut microbiome.
