If you’re working to improve digestion, reduce bloating, or just boost overall wellness, you may have heard about prebiotics. These powerful plant fibers help fuel the good bacteria in your gut and create an environment where your microbiome can thrive. Although they might not be as well-known as probiotics, their role in gut health is just as essential—if not more.
In this article, we’ll break down what prebiotics are, why they matter, and how to include them in your diet. Plus, we’ll recommend a few high-quality supplements to help you get started.
What Are Prebiotics?
Unlike probiotics, which are live bacteria, prebiotics are non-digestible fibers found in certain foods. Their job is to feed and support the beneficial bacteria already living in your digestive system. Essentially, they act as “fertilizer” for your gut.
Common types of prebiotics include inulin, fructooligosaccharides (FOS), and galactooligosaccharides (GOS). These fibers resist digestion in the small intestine and are fermented by gut bacteria in the colon.
Why Prebiotics Matter for Gut Health
A well-balanced gut microbiome has been linked to better digestion, stronger immunity, reduced inflammation, and even improved mood. Yet, without the right fuel, those helpful bacteria can’t do their jobs effectively.
That’s where prebiotics come in. By feeding the probiotics in your gut, these fibers help boost the production of short-chain fatty acids like butyrate, which supports colon health and may reduce the risk of chronic disease.
According to a 2024 review published in Nutrients, prebiotic intake is associated with improvements in stool consistency, bowel regularity, and even reduced markers of gut inflammation1.
Key Health Benefits of Prebiotics
Including prebiotics in your routine may lead to a wide range of benefits, especially for digestion and immunity. Let’s explore a few:
1. Improved Digestion and Regularity
Because prebiotics stimulate beneficial bacteria, they help improve digestion and promote regular bowel movements. They’re especially helpful for people with mild constipation or irregularity.
2. Enhanced Immune Function
A strong gut supports a resilient immune system. Prebiotics help maintain the balance of microbes that defend against harmful pathogens and reduce overall inflammation.
3. Better Mood and Mental Clarity
The gut-brain connection is real. Research suggests that nurturing your gut bacteria with prebiotics can positively impact mood, reduce stress, and support mental well-being.
4. Reduced Risk of Chronic Disease
By promoting the growth of bacteria that produce short-chain fatty acids, prebiotics may lower the risk of diseases such as colorectal cancer, type 2 diabetes, and cardiovascular disease.

Top Food Sources of Prebiotics
Fortunately, you can include these beneficial fibers in your daily meals. Foods rich in prebiotics include:
- Garlic
- Onions
- Asparagus
- Bananas (especially slightly green ones)
- Chicory root
- Leeks
- Apples
- Jerusalem artichokes
- Barley
- Oats
Although these foods are a great place to start, it may be hard to get consistent amounts from one diet alone—especially if you’re on a restrictive eating plan or have gut sensitivity.
Choosing the Best Prebiotic Supplement
If you’re looking for an easier way to support your microbiome, adding a supplement can help. When selecting one, keep the following in mind:
- Type of fiber: Look for ingredients like inulin, GOS, or FOS.
- Purity: Avoid artificial fillers, added sugars, or unnecessary additives.
- Combination with probiotics: Many formulas include both, which may offer even more digestive benefits.
- Third-party testing: Trustworthy brands will ensure quality and transparency.
Now let’s take a closer look at the best prebiotic supplements that check all the right boxes.
