What is the gut? 

These days, everyone and their mother is raving about fermented foods like kombucha, kefir, and kimchi, you are constantly bombarded with ads for products full of probiotics, prebiotics and postbiotics, and health influencers will not stop talking about taking care of gut issues you did not know you had.

If you are anything like me, all of this hype about gut health hype comes with a lot of confusion. What even is the gut? And why is it so important? 

The gut, to put it simply, is a pathway through your body that allows you to break down food and absorb nutrients. It starts in your mouth, and ends in your colon.

Gut health refers to the function and balance of everything in this system. That said, when people talk about gut health, they are usually referring to the gut microbiome – the collection of microorganisms living in your small intestines.

Your gut microbiome does more than just help you digest food. It also plays an important role in most areas of human health, including metabolism and immunity.

This is why an imbalance in your gut bacteria is linked to chronic diseases ranging from gastrointestinal inflammatory and metabolic conditions to neurological, cardiovascular, and respiratory illnesses.

Taking care of your gut, specifically your gut microbiome should therefore be a top priority. Before you start chugging kombucha, however, you need to understand what gut health is really all about.

What are probiotics? prebiotics? postbiotics?

The human gut is complex and made up of many different parts and processes. Among them are probiotics, prebiotics, and postbiotics, all of which have become buzzwords. It is for this reason that I am taking them time to explain what they are, and what they are not.


Probiotics are bacteria and yeasts that live in your gut. The most common are Lactobacillus and Bifidobacteria.

You can get probiotics from supplements and foods prepared by bacterial fermentation. Foods high in probiotics include yogurt, kefir, sauerkraut, tempeh, and kimchi.

Although the evidence is promising, more research is needed on the health benefits of probiotics, that is, the scientific community still disagrees about what the actual benefits are, as well as about which strains of bacteria are good, and which are bad. Some researchers even warn about possible negative effects of probiotics, and call for caution and strict regulation.

A growing number of food and supplement companies spike their products with probiotics to make them “gut-friendly.” Given the uncertainty surrounding the role of probiotics, I recommend avoiding products like these until more conclusive research is available.


Prebiotics are foods that feed your gut bacteria, helping to create a healthy gut microbiome. They can be found in high fiber foods like fruits, vegetables, and whole grains.

Some food and supplement companies also spike their products with prebiotics, but instead of using whole food sources of prebiotic fiber, they use cheap, heavily-processed ingredients like guar gum and inulin. This is not a healthy way to feed your gut bacteria.


Postbiotics are the bioactive compounds that probiotics (bacteria) produce when they consume prebiotics (fiber). Although postbiotics are the waste products of probiotic bacteria, they offer various health benefits to your body. For instance, postbiotics include vitamins, amino acids, antimicrobial peptides slow the growth of harmful bacteria, and short-chain fatty acids help healthy bacteria flourish.

In most cases, you should be able get all the probiotics, prebiotics, and postbiotics you need from a balanced diet. If you do decide to supplement, keep in mind that it is hard to predict the appropriate dose or type without significant, in depth testing under the guidance of a trained healthcare practitioner. And even then, it can still be challenging. 

What is the best gut health protein powder?

When it comes to gut health, picking the right protein powder is super important. Protein powder is something you consume regularly, if not every day, so small amounts of problematic ingredients can have a big impact.

Many protein powders are made with ingredients that can cause painful side gastrointestinal (GI) effects and long term gut health problems. Among these ingredients are food additives, dairy-based proteins, and protein concentrates and isolates. 

Avoid food additives

Regularly eating emulsifiers, thickeners, sugar substitutes, and other additives can not only upset your stomach, but also alter the composition of your gut microbiome – the collection of microorganisms living in your gut. This can lead to gut dysbiosis, which is linked to a number of chronic digestive issues

Here is a list of the most common food additives in protein supplements:

  • acacia fiber
  • acacia gum
  • acesulfame potassium
  • artificial flavors
  • ascorbic acid
  • aspartame
  • calcium carbonate
  • carrageenan
  • cellulose gum
  • dextrin
  • dicalcium phosphate
  • dipotassium phosphate
  • erythritol
  • gellan gum
  • guar gum
  • gum arabic
  • inulin
  • locust bean gum
  • maltitol
  • maltodextrin
  • mono- and diglycerides
  • ‘natural’ flavors
  • rice bran extract
  • rice dextrin
  • rice hulls
  • rosemary extract
  • silica
  • silicon dioxide
  • sodium alginate
  • soluble corn fiber
  • sorbitol
  • soy lecithin
  • sucralose
  • sunflower lecithin
  • tocopherols
  • tricalcium phosphate
  • xanthan gum
  • xylitol
  • zinc oxide

Avoid dairy-based proteins

Dairy-based proteins like whey and casein, although not an issue for everyone, can cause side effects like bloating and diarrhea. This is in part because they contain lactose, a sugar most adults cannot fully digest.

Avoid protein concentrates and isolates

Most protein powders are made from protein concentrates and isolates, which have been mechanically and or chemically stripped of everything but the protein, including the enzymes, fiber, and other natural digestive aids that help you break them down. As a result, they can cause digestive issues and possibly even disruptions to your gut microbiome

Finding a protein powder free from food additives, dairy-based proteins, and protein concentrates and isolates is hard.

In fact, 99% of protein supplements contain one or more of these problematic ingredients. This is why we created drink wholesome. Keep reading to learn more about why we make the best protein powder for gut health.

NOT our ingredients

  • acacia gum

  • acesulfame potassium

  • artificial flavors

  • carrageenan

  • erythritol

  • guar gum

  • inulin

  • maltodextrin

  • 'natural' flavors

  • silica

  • soy lecithin

  • sucralose

  • xanthan gum

  • xylitol

Note that instead of using protein concentrates or isolates, we use whole food protein sources like collagen, egg whites, and almonds, which are easier to digest and absorb.

Whole food protein sources also have unique digestive benefits: collagen can reduce bloating and improve digestive symptoms, egg whites can help restore your mucosal intestinal barrier, and almonds can improve the composition of your gut microbiome.

You will also notice that we do not add digestive enzymes, probiotics, or prebiotic fiber to our protein powders like other companies.

That is in part because research into the benefits of doing so is inconclusive at best – in some cases, adding probiotics to food can actually make gut issues worse.

It is also because whole foods do not have artificially altered to make them easy to digest or good for your gut. If a company is adding digestive enzymes, probiotics, or prebiotic fiber to its products, it is probably trying to mask the fact that it stripped these components away during processing. 

In conclusion, our customers experience fewer digestive issues with our gut health protein powder than with any other type of protein supplement. Order samples to see for yourself.

What role does protein play in the gut?

Protein, which is made up of amino acids, is integral to the health of your gut lining.

In addition to supporting intestinal cell health, amino acids derived from dietary protein are needed for tissue repair and maintenance. They are also essential for synthesizing the digestive enzymes, which help you break down and absorb the food you eat, and are involved in the production of neurotransmitters, which regulate gut motility.

How can protein powder support gut health?

Adding protein powder to your diet is an easy way to fill in nutritional gaps and ensure that you are meeting your protein needs. It is especially convenient for people with busy schedules or dietary restrictions.

Not all protein powders are created equal, however, so it is important that you be mindful of the ingredients, and monitor how it interacts with your gut.

Also keep in mind that every gut is different, so finding a protein powder that works for you may require some experimentation.

Finally, it is recommended that you consult with a dietitian for personalized nutrition advice when making significant changes to your diet. A good practitioner can make a huge difference in helping you identify what ingredients work (or not not work) for you.

Verified Purchase I'm only filling this out because I haven't found anything else like it. My system is sensitive to everything. I get headaches and stomachaches so easy from anything but regular old sugar for instance, and even that I can't have too much of. I'm using your protein powder (with the maple sugar) every morning, and I'm convinced there isn't a better one out there. I'm a 50 year old trying to lose 50 pounds and feel like your powder is the closest to something natural I can find which is good at my age, lol. I'm very proud of finding you guys and already tell everyone about it.
