Top 9 Natural Gut Health Supplements

There’s a wise saying that goes: “When in doubt, start with the gut”. In other words, if you’re struggling with health symptoms, you can take comfort in knowing that healing the gut is the right place to start. We’re not just referring to digestive symptoms, either. Chronic low energy, joint pain, acne, eczema, depression, low immunity, and difficulty losing weight have all been linked to an imbalanced gut microbiome.

Many people also suffer from chronic gut conditions. Twelve percent of Americans are said to have irritable bowel syndrome, and it’s believed even more cases go undiagnosed. (1) Leaky gut syndrome, SIBO, celiac disease, gut dysbiosis, and autoimmune conditions are on the rise, which serves as a reminder that caring for gut health is a priority.

Where should you begin? There’s no arguing the path to a healthy microbiome is eating more plant foods and making positive lifestyle changes, like replacing happy hour with a yoga class. However, studies have shown that certain herbs, amino acids, and a group of antioxidants in tea can be supportive for improving symptoms and restoring gut health. Let’s take a look at which supplements made the list.

Disclaimer: For dosage and safety, it’s important to consult with a healthcare practitioner before adding any supplement to your diet, especially if you’re pregnant or nursing.

1. Probiotics

Out of all the supplements you could take, a high-quality probiotic is probably the most important one. These beneficial bacteria are found all over the human body and lay the foundation for a healthy gut.

You can think of probiotics as the highly intelligent and high functioning housekeepers of the digestive system— they do so much to keep our health in check.  

Probiotics fight bad bugs and keep harmful pathogens away, promote a healthy bacterial balance, and boost immunity and resistance to infections. (2)(3) Some strains of probiotics have even been linked to preventing obesity. (4) They break down food, promote healthy bowel movements, aid in nutrient absorption, and help produce certain B vitamins— all in a day’s work. (5)

Sadly, the modern-day diet and lifestyle tends to be unsupportive for these guys. Processed foods and refined sugar, antibiotics, excessive alcohol, and high stress can all contribute to wiping out your good bacteria. This leaves your microbiome highly susceptible to allowing bad bacteria and harmful pathogens to take over.

Having more bad bacteria than good—  a condition known as gut dysbiosis— sets the stage for chronic health conditions to develop. (6) This is why it’s often necessary to take a probiotic supplement for gut repair and maintenance.

You can also get probiotics in your diet by eating fermented foods such as miso, tempeh, sauerkraut, coconut milk yogurt, beet kvass, kimchi, and water kefir.

Caution: If you’re not used to eating fermented foods, start small (for example, one tablespoon of coconut milk yogurt each day), and work your way up to the recommended serving. This will prevent gas, bloating, and other digestive symptoms that can show up as you begin to rebalance your gut bacteria.

How to Choose a Probiotic Supplement:

There are many different strains of probiotics with intense sounding names— such as lactobacillus acidophilus and bifidus— and they all provide different health benefits.

For example, some strains of bacteria work best for acne, while others are known for fighting yeast and fungal infections. This area is where you’ll need to do some research, or speak with a healthcare practitioner to find the right strain(s) for your needs.

As a general guideline for choosing a probiotic, you’ll want to:


  • Check the expiration date on the probiotic supplement.

    Ensure your probiotic is not close to expiring. As living cultures, you want to make sure you’re ingesting these bacteria while they’re alive.
  • Choose a probiotic that’s enteric-coated.

    Enteric coating on a probiotic supplement increases the chances of the bacteria surviving a long journey through stomach acid, all the way to the intestines (7).
  • Choose a probiotic supplement with 10-20 billion CFU strains (or more).

    The potency of a probiotic is measured by it’s CFU, or colony-forming unit number. This number can range anywhere from 1 billion to 100 billion. For adults, the daily recommendation is 10-20 billion CFU’s (8).  A high-quality probiotic also will guarantee a CFU at expiry, which means it will contain at least the amount of bacteria stated on the label when it’s on its last legs.
  • For long-term supplementation, choose a multiple strain probiotic.

    While more research is needed to understand the long-term effects of supplementing with a single strain, versus a multiple strain probiotic, what we do know is that a diverse microbiome with many different types of bacteria is required for optimal gut health. (X)

2. Prebiotics

With a nearly identical name to probiotics, you’d think prebiotics are the same thing, but they’re not. They’re more like the “precursor” to probiotics.

Prebiotics are found in the fiber of plant foods and act as food for healthy gut bacteria. After all, probiotics are living cultures and need to be fed a healthy diet, too! Sometimes called gut fertilizer, prebiotics are necessary for growing a colony of beneficial gut bacteria. (10)

Isn’t it crazy to think that without prebiotics, we wouldn’t have probiotics, and neither you or I would be here?

There are many different types of prebiotics. The most common are inulin, oligofructose, fructooligosaccharides (aka fructans), galacto-oligosaccharides, and resistant starch. You may have also heard of the prebiotic pectin, which your Grandma used to make strawberry jam.

Since these fibers aren’t digested by the body, they reach the small intestine still intact and head straight to the colon to be “digested” or fermented by healthy gut bacteria that live there. Although this sounds like a recipe for flatulence, prebiotics can actually help control strains of bacteria that cause excessive gas! (11)

Prebiotics can be taken in capsule or powdered supplement form. You can also get them in your diet by eating more of these foods:


  • Chicory root
  • Garlic
  • Onion
  • Jerusalem artichoke
  • Bananas
  • Leeks
  • Apples
  • Bananas (and unripe bananas)
  • Green banana flour
  • Dandelion greens
  • Barley
  • Oats
  • Wild blueberries
  • Beans and lentils
  • Flaxseed
  • Seaweed

It’s recommended to get at least five grams of prebiotics daily for optimal gut health. In addition to these foods, a prebiotic supplement can help you meet your intake.


3. Tea Polyphenols

Why do regular tea drinkers live longer? It may have to do with the connection between the active ingredient in tea, called polyphenols, and their positive effect on gut bacteria.

Polyphenols have been most discussed as being supportive for the cardiovascular system and healthy blood sugar levels. (12) But a lesser-known fact is that they may also increase healthy gut bacteria. (13)


One animal study found that both green tea and black tea increased the number of healthy gut bacteria associated with lean body mass— and reduced the number of gut bacteria associated with obesity. (14) Whaaat? How could this happen?

Since the molecules in tea are too large to be absorbed in the small intestine, they must remain in the digestive tract for longer periods of time to be broken down. During this “waiting period”, they feed healthy gut bacteria. (15) In this sense, the polyphenols in black tea act as a prebiotic. But, get this: polyphenols have also been shown to inhibit the growth of pathogenic bacteria, which suggests they also take on a similar quality of probiotics. (16)

Who knew that drinking tea could be one of the most effective and enjoyable rituals for gut health?

While black tea is the richest source of polyphenols, all varieties of green tea and herbal tea will contain moderate amounts. (17)

How to Choose a High-Quality Polyphenol Rich Tea

When it comes to getting polyphenols from tea, quality matters. The polyphenol content will largely depend on how the tea was grown, harvested, processed, and brewed.

To maximize the gut health benefits, you’ll want to look for a tea that meets these requirements:



  • Organic.
  • Made with leaves from the first flush (harvest), which yield a higher polyphenol content.
  • Make sure the leaves were minimally processed and not exposed to high heat, which can damage the polyphenol content.
  • Triple Toxin Screened for pesticides, heavy metals, and toxic mold.
    Otherwise, you risk ingesting anti-nutrients that are counter-productive to gut healing.

In addition to black tea and green tea, there are plenty of other polyphenol-rich foods you can eat on a regular basis. You probably already have some of them in your kitchen: olive oil, black olives, raw cacao powder, and red wine (small amounts, in moderation). Here’s an in-depth list of polyphenol-rich foods.

4. Licorice Root Extract

Licorice root extract is a powerful natural anti-inflammatory that can be used to improve a variety of gastrointestinal symptoms. Not only does it help soothe and support the repair of the gut lining, it can also be taken to reduce stomach pain, heartburn, ulcers, and indigestion. (18)

As an adaptogenic herb, licorice root is also used for supporting the adrenal glands and reducing stress levels— which may allow it to be especially helpful for those whose symptoms are triggered or worsened by stress. (19)

How to Take Licorice Root

Licorice root can be brewed as a tea, or taken as a chewable tablet or capsule.


Licorice contains glycyrrhizinic acid, an immune-boosting acid that can negatively interact with certain medications (including those that lower potassium levels and increase hypertension). Err on the side of caution, and check with your doctor before taking it.


5. Reishi Mushrooms

In Chinese medicine, reishi mushrooms have been used for over 2000 years for energy, vitality, and fertility. (20) However, it may be another best-kept secret for reversing gut dysbiosis, and positively altering healthy gut bacteria.

A study on mice showed that taking reishi mushroom extract with foods high in saturated fat had the ability to reverse bad bacterial overgrowth induced by a high-fat diet. (21)

Additionally, reishi mushroom reduced fat tissue development, gut inflammation, and prevented harmful bacteria in the bloodstream (22)

How to Take Reishi Mushroom

You can take reishi mushroom in powdered form and add to smoothies, tea or coffee, or use dehydrated reishi mushrooms for cooking.

6. Collagen

For hundreds of years, our ancestors consumed collagen from animal bones by making bone broth. It wasn’t until recently that collagen protein supplements (sourced from cattle or fish bones) took the world by storm for promoting gut health.

Collagen is the most abundant protein in the body. Being packed with anti-inflammatory amino acids such as l-glutamine, proline, and glycine, it’s also one of the most discussed supplements for leaky gut syndrome, IBS, and supporting immunity. (23)

In particular, l-glutamine assists with healing irritated tissue in the digestive tract, which suggests it may be helpful for IBS or irritable bowel diseases, such as Crohn’s disease. (25) It’s also believed that collagen helps seal the holes in the gut lining that cause leaky gut. (24) However, more clinical trials are needed to confirm this.

How to Take Collagen:

As a tasteless powder, collagen mixes well with smoothies, juices, and soups. You could even add it to a gut supportive, polyphenol-rich dessert like avocado cacao mousse. Collagen dissolves well in virtually anything, so don’t be afraid to get creative.

A note on quality: Always source bones and collagen supplements from grass-fed, pasture-raised cows to avoid growth hormones and antibiotics.

Caution: If you experience digestive symptoms after taking protein supplements, you may want to start adding collagen to your diet by making a bone broth instead. Collagen is easily absorbed when it’s released from simmering bones and connective tissue for long periods of time, with added vegetables and herbs to create a tasty, healing broth.

7. Berberine

Berberine is an alkaloid found in the roots and stems of potent antibacterial herbs, such as tree turmeric and goldenseal. It’s commonly used as a natural antibiotic in both Ayurvedic and traditional Chinese medicine for GI tract infections and destroying harmful pathogens, such as H.Pylori, candida, and staph infections (which often go undetected) (25)

Berberine is safe to take daily, and studies show it can even lower blood sugar levels and fight obesity by activating a metabolism-boosting enzyme called AMPK. (26)

The unique benefit of berberine is that it’s as powerful as an over the counter medication for killing bacteria— but unlike pharmaceuticals, it only destroys bad bacteria and leaves the good bacteria in tact. This is a major win for gut health, as just one course of antibiotics can negatively impact your gut bacteria for a year. (27)

8. Aloe Vera

Of all the botanicals out there, aloe vera is one we see most. It’s in everything from skincare products to bottled juices in corner stores. When taken from the pure gel or liquid of the plant beneath the leaf, you’ll discover a powerful natural remedy for improving digestion, relieving constipation, and soothing intestinal inflammation. (28)(29)


As an alkaline plant, aloe vera can also help neutralize the harmful impact of acidic foods, such as refined sugar and animal protein, which create the environment for bad bacteria and disease to thrive. (30)

How to Take Aloe Vera

If you have an aloe vera plant, you can take the juice directly from the plant and add two tablespoons of the gel to any juice or smoothie recipe. It’s super refreshing when mixed with  cucumber juice, filtered water, and lime juice.

Caution: Aloe vera should be used sparingly as it has a natural laxative effect, and should not be taken in high doses.

It may also interfere with certain diabetic and diuretic medications, so if you are currently experiencing any health issues, be sure to consult with a healthcare practitioner before adding aloe vera to your supplement regime.

When purchasing aloe vera juice, make sure it’s pure aloe with no sugar or other additives.

9. Curcumin

Curcumin, the active ingredient in turmeric, also falls under the gut-supportive polyphenol umbrella. It’s been called a natural pain killer for its ability to fight inflammation and may help improve symptoms of digestive disorders. (31)


In the past, an issue with curcumin supplementation was that despite all of its amazing health benefits, it had a very poor absorption rate. Clinical trials used unrealistic and large amounts of turmeric for their findings, which weren’t do-able for people at home— however, a solution has been found.

You can now find supplements that are combined with phospholipids to form “curcumin phytosome”, which allows a much greater delivery to the bloodstream. This highly absorbable form of curcumin is said to be much more effective in pain relief and the natural treatment of gastrointestinal diseases. (32)

As you can see, nature has provided a generous pharmacy for healing and supporting the gut. While it’s ideal to take certain supplements regularly (such as probiotics), not all supplements will need to be taken long-term. You can even begin improving your gut health right now by sipping on a strong cup of black tea.
