Let's Celebrate Prebiotics
Join the Global Prebiotic Association’s annual industry campaign celebrating the role of prebiotics in microbiome health: their benefits, their types and how they’re used.
The gut is in constant contact with the brain, the immune system, the skin and metabolism. Gut microbes do a lot of that talking, and prebiotics are what feed them. That’s the idea behind this year’s theme, Powering the Microbiome.
From Gut Health to Systemic Wellness
When gut microbes ferment prebiotics, they produce short-chain fatty acids (SCFAs) and other compounds that signal well beyond the gut.
Here's where that research is heading:
Gut–Brain
SCFAs and other compounds signal to the brain through the vagus nerve, the immune system and the bloodstream. Research on prebiotics and mood, stress and cognition is growing quickly.
Gut–Immune
Roughly 70% of the immune system sits in the gut. Prebiotics feed the microbes that help keep the gut barrier strong and immune signaling in balance.
Gut–Skin
Researchers are starting to connect the gut microbiome to skin health, through inflammation and the compounds gut microbes release into circulation. It’s early science, and it’s moving fast.
Gut–Metabolic
SCFAs can influence appetite hormones like GLP-1 and PYY, along with blood sugar response. Metabolic health is one of the most studied areas for prebiotics.
Research now connects prebiotics to brain, immune, skin and metabolic health, and the standards for proving those benefits keep getting clearer.
Feeding the Microbes Already in the Gut
Prebiotics are central to microbiome science and meet growing consumer interest in natural, gut-focused support for immunity, digestion, cognition and metabolism. Unlike probiotics, which add live bacteria, prebiotics feed the beneficial microbes already in the gut.
The GPA defines a prebiotic as:
A compound or ingredient that is utilized by the microbiota producing a health or performance benefit.
Types of Prebiotics
As interest in prebiotics expands, so too does the diversity of ingredients classified within this category. Prebiotics are now recognized to benefit more than just digestive health, with different types offering unique, science-backed health effects. GPA recognizes certain categories as established and/or emerging types of prebiotics. We continuously monitor the science surrounding prebiotics and these type guides are updated as new science emerges.

Let's Talk Synbiotics
INFOGRAPH: What Are Synbiotics?
Synbiotics are mixtures of live or inanimate microorganisms co-administered with substrate(s) selectively utilized by either the co-administered microorganism or the host’s indigenous microorganisms, conferring a health or performance benefit.
Synbiotics White Paper
Derived from the Synbiotics infrograph, the GPA has developed a Synbiotics White Paper aimed to provide a more technical overview of the types of synbiotics, formulations, health benefits, health claims and opportunities in the space.
Formulating, Formats, and Applications
Tap into the world of Prebiotics with some of these frequently asked questions on sources and applications. Your insight for answers to the most common queries about prebiotic formats and their diverse applications.
Prebiotics can be taken at any time of day, but there isn’t a specific “best” time. It’s more important to maintain a consistent daily intake. Prebiotics serve as a food source for beneficial gut bacteria, and their effects are gradual and long-term. It’s recommended to incorporate prebiotics into your daily diet to support a healthy gut microbiome.
Prebiotics can be incorporated into various food products, including yogurt, cereal, energy bars, and dietary supplements. Common prebiotic ingredients include inulin, oligosaccharides, and fructooligosaccharides (FOS). Manufacturers often add these ingredients to their products to enhance their prebiotic content and health benefits.
Many natural foods contain prebiotics, including:
- Garlic and onions: Contain inulin and fructooligosaccharides.
- Bananas: Contain resistant starch, a type of prebiotic.
- Asparagus: Rich in inulin.
- Jerusalem artichokes: High in inulin.
- Chicory root: Contains inulin and oligofructose.
- Whole grains: Such as wheat, barley, and oats, which contain resistant starch and other prebiotic fibers.
The choice of prebiotic formulation depends on your specific dietary preferences and goals. Consider factors such as the type of prebiotic, dosage, and potential side effects. It’s essential to consult with a healthcare professional or nutritionist for personalized advice based on your health and dietary requirements.
Yes, prebiotic powders can be mixed with various beverages or foods, such as water, smoothies, or yogurt. This allows for flexibility in incorporating prebiotics into your daily routine. Just follow the recommended dosage and mixing instructions provided on the product label to ensure proper intake.
To incorporate prebiotics into your daily routine, consider adding prebiotic-rich foods to your meals and snacks. You can also use prebiotic supplements or fortified products as a convenient option. Start with a lower dosage and gradually increase it to minimize potential digestive discomfort. Consistency is key for long-term benefits.
Yes, you can use prebiotic products alongside probiotics or other supplements. In fact, combining prebiotics with probiotics can have a synergistic effect, as prebiotics provide the “food” for probiotic bacteria, enhancing their survival and effectiveness in the gut. However, it’s advisable to consult with a healthcare professional to determine the appropriate combinations and dosages for your specific health goals.
