Gut health is a popular topic of discussion. You have healthcare practitioners preaching about the connection between gut health and disease, Instagram influencers showing you their favorite probiotic-rich meal, chefs giving tutorials on “gut-loving” recipes, and just about everyone in between shouting something about “LOVE YOUR GUT.”

There’s no denying that the health of your gut is important for your overall health and well-being. Whether it’s mental health, joint health, cardiovascular health, or obviously digestive health, there’s some sort of link between the balance of your gut bugs and the state of your health.

And because of this, we sit on the side of all the health-loving fellows and agree that keeping your gut healthy and happy means keeping your entire body the same way!

While most people will tell you that probiotics are a huge thing for supporting gut health, we have something a little bit different up our sleeve—they’re called prebiotics, and they’re the latest and greatest thing when it comes to keeping your gut balanced.

What Are Probiotics?

Probiotics are the gut supplement we always hear about. The live microorganisms that, when administered in high amounts, can offer a number of positive benefits for the person taking them 1.

But the benefits aren’t an across-the-board thing—they differ depending on the strain you’re taking. For example, Lactobacillus species naturally inhabit the small intestine and are great for supporting the gut barrier, bowel function, and immunity.

Bifidobacterium, on the other hand, reside in the large intestine (or colon) and support digestion, mood, and stress response. The different locations in your gut that bacteria reside translates to different health benefits.

Lactobacillus and Bifidobacteria are two of the most widely consumed probiotics, but there are other strains like Saccharomyces, Streptococcus, Enterococcus, Escherichia, and Bacillus.

Supplements can contain a single strain or a mix of many; single strains often are used to treat specific conditions rather than the gut’s overall health. But regardless of what you choose, the goal of probiotic supplements is to repopulate and rebalance the gut microbiota, thereby improving health outcomes.

With prebiotics, they work a bit differently. Prebiotics are not organisms per se; rather, they are the food that supplies these organisms' fuel. Just as humans and all other living, breathing species need food to survive, the good bugs in your gut do, too.

And if you’re not feeding them what they need (i.e., prebiotic fiber), they’re going to die. These prebiotics are selectively used by host microorganisms (your gut bacteria) and are able to manipulate host microbiota 2.

Basically, taking prebiotics is important because they help nourish specific probiotic strains populating the gut rather than contribute additional strains.

Generally speaking, prebiotics are actually different types of complex carbohydrates. Because the body doesn’t have the enzymes needed to break them down, the microbes in your gut metabolize them to generate short-chain fatty acids (SCFAs) like acetate, propionate, and butyrate 3. These SCFAs offer their own health benefits to the body.

Besides taking a prebiotic supplement, you can also get prebiotic fiber from many food sources, including:

  • Chicory root
  • Dandelion greens
  • Jerusalem artichoke
  • Garlic
  • Onions
  • Leeks
  • Asparagus
  • Apples
  • Bananas

Why Is Gut Health Important?

Most people relate the gut to just the digestive system, and while the digestive system obviously plays a huge role in gut health, gut health is so much more.

Broadly speaking, the gut encompasses both the stomach and the intestinal tract, and when we’re talking about gut health, we’re referring to the balance of microorganisms populating these spaces; is it more food bacteria or more bad bacteria?

Gut health, directly and indirectly, affects your entire body. Here’s why maintaining a healthy and balanced microbiome is important for more than just your digestive system:

  • Nutrient production (vitamin K, certain B vitamins)
  • Mood regulation and mental health
  • Digestion
  • Joint health
  • Cognitive function
  • Hormonal balance
  • Sleep

Signs of a gut imbalance

There are tests available to determine if you have dysbiosis, leaky gut, or any other digestive/gut issues, but some of the most common symptoms that will tell you something isn’t quite right are:

  • Abdominal discomfort (gas, bloating, diarrhea, constipation)
  • Mood imbalances
  • Poor focus and concentration
  • Skin issues (eczema, acne, dry, itchy skin)
  • Sugar cravings
  • Sleep disturbances
  • Weight changes
  • Poor immunity

If you’re struggling with any of these, chances are there’s something going on in your gut.

Why Prebiotics Matter

Digestive health

The heath of your digestive system relies heavily on the health of your gut and the populations of microbiota residing in it. When these populations become imbalanced, and the bad guys outnumber the good, it spells trouble for your entire body.

Because prebiotics support the growth of specific bacterial colonies already residing in the gut, research shows that prebiotics help to increase relative numbers of Lactobacillus and Bifidobacterium species, as well as alter bacterial metabolism.

When these bacteria are thriving, they produce large amounts of short-chain fatty acids that possess antimicrobial activity and enhance the integrity of epithelium lining the gastrointestinal tract 4.

When your gut barrier is sealed, food stays within your GI tract, which prevents food sensitivities, enhances nutrient digestion and absorption, and prevents chronic low-grade inflammation and disease development.

Weight management

Did you ever think a healthy gut could help you lose weight? It can! Gut bacteria won’t have a direct effect on weight loss, but their activities have a rippling effect through your entire body, which can help to control weight by regulating energy expenditure, metabolism, and hormones.

Research shows that an imbalanced gut is linked to obesity, and that low fecal bacterial diversity is associated with adiposity and dyslipidemia, impaired glucose regulation, and higher levels of low-grade inflammation 5, all of which contribute to body composition and weight.

A healthy microbiome may help to support weight loss by 6:

  • Affecting intestinal gene expression involved in energy balance
  • Regulating intestinal barrier function
  • Regulating satiety hormone release (leptin and ghrelin)
  • Generating short-chain fatty acids (SCFAs)
  • Regulating digestion and absorption of nutrients

Mood and brain function

Your brain and gut work on something called the gut-brain axis, and the health of your gut has a lot to do with how well your brain functions. Changes in the diversity and health of the gut microbiome is an underlying factor involved in the development of several neurological disorders involving inflammation 7.

Prebiotics help balance out the gut microbiome, leading to less inflammation and fewer cognitive symptoms.

Some research also finds that prebiotics may influence the central nervous system (CNS) by modulating neuroinflammation, which is important for treating cognitive impairment and mood disorders like anxiety and depression 7.


With more than 70% of your immune system residing in your gut, it should be pretty obvious that a healthy gut makes for a healthy immune system. Many components of the immune system are regulated by the microbiota populating the skin, oral cavity, gastrointestinal tract, genitals, and respiratory tract 8.

When your gut bugs are imbalanced, there’s not enough of the good guys to support your internal and external defense mechanisms, hence why you get sick or ill.

Not to mention, the short-chain fatty acids produced by fiber fermentation contribute to the production of important inflammatory and immune cells like IL-8, TNF-α, IL-6, CXCL1, and CXCL10 through their role as energy substrates 9, as well as regulate various immune system components (neutrophils, monocytes, and macrophages) 8.

Basically, an imbalanced microbiome is a breeding ground for inflammation and disease.

How To Support Your Gut

When it comes to supporting a healthy gut, there are loads of things you can do. A healthy diet is pretty much the best, but other things like stress management, proper sleep, physical activity, avoiding food triggers, and of course, supplementation are also key.

Probiotics are generally the number one supplement recommendation, but even with those, there are several things to consider. Is it shelf-stable, or does it need refrigerating? How many CFUs (colony forming units) does it contain? What strains are in it? What am I using it for?

Probiotics are highly specific to the condition you’re working with and what you’re looking to achieve, but the thing about prebiotics is that everyone needs them regardless of the condition.

Prebiotics aren’t like probiotics in the sense that specific strains cater towards helping certain bacteria flourish; prebiotics help the bacteria that already exist in your gut—no matter the strain. While yes, they do have a preference towards supporting certain ones, by no means do they discriminate.

And that’s the exact reason we love them so much.
