Is Prebiotic Soda Good for You? Dietitians Weigh In
Enjoy a flavorful fiber boost that nourishes your microbiome and keeps sugar in check.
What Is Prebiotic Soda?
Prebiotic soda is a carbonated beverage formulated to contain prebiotic ingredients that nourish your gut’s beneficial bacteria. Registered Dietitian Bonnie Taub-Dix describes prebiotic sodas as resembling traditional soft drinks in familiar flavors—think cola, orange, and cherry lime—yet often containing less added sugar than conventional sodas.
Prebiotics are the specific food compounds that fuel the growth of healthy gut microbes. Unlike probiotics, which are live bacteria, prebiotics act as nourishment for these bacteria, promoting digestive health and balance. Importantly, humans cannot digest prebiotics themselves—but our gut microbiome can.
- Prebiotics support a healthy environment for gut bacteria
- They are usually found in fiber-rich foods
- Most prebiotic sodas are lower in sugar compared to regular sodas
According to the International Scientific Association for Probiotics and Prebiotics (ISAPP), consuming at least 5 grams of prebiotics daily is recommended, but there’s no formal dietary guideline. Most prebiotic sodas provide between 2 to 9 grams of dietary fiber per can, though not all dietary fiber is prebiotic fiber.
Natural Sources of Prebiotics
- Chicory root
- Garlic
- Leeks
- Onions
- Asparagus
- Jerusalem artichoke
- Bananas
- Sweet potatoes
Commercial prebiotic sodas typically source their prebiotics differently. For example, Poppi uses apple cider vinegar and agave inulin, while Olipop combines cassava root, chicory root, and other fibers.
Does Prebiotic Soda Offer Any Health Benefits?
Prebiotics have several possible health effects, most notably supporting digestive function, bolstering immunity, and enhancing mineral absorption.
- Digestive health: Prebiotics feed the “good” gut bacteria, helping maintain a balanced microbiome.
- Immune support: A healthy gut environment is linked to a robust immune system.
- Mineral absorption: Prebiotics can enhance absorption of minerals like calcium and magnesium.
- Reduced GI symptoms: Certain prebiotics, such as galactooligosaccharides (GOS), may relieve gas, bloating, and abdominal pain and decrease anxiety symptoms in healthy young adults.
- Lower cholesterol and heart benefits: Some oligosaccharide fibers are connected with improved heart health and lower cholesterol.
Taub-Dix also points out that most American adults fall short of recommended daily fiber intake, and prebiotic sodas could help close that gap. Olipop, for example, delivers up to 9 grams of fiber per can, which is more than a third of the recommended intake for women.
Interestingly, the distinction between fiber and prebiotics is important: most prebiotics are dietary fibers, but not all dietary fibers serve prebiotic functions.
Low Sugar Alternative
One major advantage of prebiotic sodas over regular sodas is their lower sugar content:
| Beverage | Added Sugar (per can) | Fiber (per can) |
|---|---|---|
| Regular soda | 38g | 0g |
| Prebiotic soda (Olipop) | 2–5g | 2–9g |

If made without artificial sweeteners and containing little added sugar, prebiotic sodas may also contribute to hydration.
Expert Opinions: Are Prebiotic Sodas Really Healthy?
Nutritionists generally agree that prebiotic sodas can help fill a fiber gap, especially for those not getting enough from whole foods. One core ingredient is inulin, a prebiotic fiber naturally present in chicory root, agave, and other plant sources. Inulin can help diversify gut microbes—a marker of a healthy gut, according to nutrition experts.
However, experts caution against relying on prebiotic sodas alone for fiber. Whole foods remain the “gold standard” because they offer a broader nutrient package including vitamins, minerals, and antioxidants. Processing can change the structure and effect of prebiotic fibers, and plant foods deliver a richer nutritional profile than any single beverage can.
- Best sources of fiber: Whole grains, beans, nuts, seeds, fruits, and vegetables.
- Prebiotic sodas supply only the types of fiber in the drink; whole foods provide diverse fiber types and nutrients.
- If you eat mostly plant-based, fiber-rich foods, you may not need prebiotic sodas.
Cara Anselmo, RDN, notes that a moderate approach can work: “If someone’s going to have a soda once a day, I would rather they drink something with stevia than something that has 50 grams of added sugar.”
Prebiotics Are Not New
Nutritionists remind consumers that prebiotics aren’t a new concept—they’ve always existed in plant foods. Diverse diets fostering varied gut microenvironments tend to be healthier than those high in refined sugars and processed foods.
Potential Downsides & Who Should Be Cautious
For some consumers—especially those with sensitive digestive systems, irritable bowel syndrome (IBS), or food intolerances—prebiotic sodas may pose risks.
- Digestive issues: Inulin and other fibers can trigger bloating, gas, or abdominal discomfort when consumed in large amounts.
- People on low-FODMAP diets may need to avoid or limit prebiotic sodas.
- Symptoms may include bloating, abdominal pain, and changes in bowel habits.
For healthy individuals, prebiotic sodas can be a fun way to add fiber, but moderation is important. Registered Dietitians emphasize paying attention to your body and not replacing whole foods with fiber-fortified sodas.
Who Might Benefit Most?
- People who seldom eat fiber-rich foods and want a convenient boost
- Soda drinkers seeking a lower-sugar alternative
- Those interested in supporting their gut health but struggling to meet fiber intake goals
Who Should Avoid or Limit?
- Individuals with IBS, IBD, or sensitive digestive systems
- Children (consult with a pediatrician for appropriate fiber sources)
- Anyone experiencing GI discomfort with prebiotic sodas
Comparing Prebiotic Sodas to Whole Foods: A Table
| Feature | Prebiotic Soda | Whole Foods |
|---|---|---|
| Fiber Content | 2–9g per can | Varies: Up to 10g/serving (e.g., beans, vegetables) |
| Added Sugar | Low (2-5g) | Usually none |
| Nutrient Variety | Limited (fiber, some minerals) | High (fiber, vitamins, minerals, antioxidants) |
| Gut Health Benefits | Targets specific fibers/prebiotics | Full spectrum, including polyphenols and micronutrients |
| Potential Drawbacks | Bloating (in sensitive individuals), may not be suitable for all | Generally well-tolerated unless food allergies/intolerances |
Buzzy Trends & Marketing: Why the Hype?
Prebiotic sodas have grabbed major attention thanks to their promise of gut health benefits, their “better-for-you” branding, and their flavorful alternatives to sugar-heavy sodas.
Brand marketing often emphasizes:
- Gut health and microbiome support
- Low sugar content
- No artificial sweeteners
- Innovative flavors
- Plant-derived ingredients
However, while the science is encouraging, experts caution that the fundamental answer to gut health has always been found in vegetables and other whole plant foods.
Best Practices: Maximizing Your Gut Health
- Prioritize whole, plant-based foods (whole grains, beans, vegetables, fruits, nuts, seeds)
- Enjoy fermented foods (yogurt, cottage cheese, kimchi, unpasteurized pickles, kefir, sauerkraut) for probiotic support
- Use prebiotic sodas occasionally to supplement a fiber-poor diet—but not as your main source
- Monitor your body—if you experience bloating or discomfort, adjust your intake
- Consult a healthcare provider if you have digestive sensitivities or specific dietary needs
Frequently Asked Questions (FAQ)
Q: What are prebiotics, and do you need them in your diet?
A: Prebiotics are carbohydrates (usually fibers) that feed beneficial gut bacteria. Your gut health relies on a balanced microbiome, so prebiotics are helpful—but ideally, get them from foods like onions, leeks, bananas, and whole grains.
Q: Can prebiotic sodas replace fiber-rich foods?
A: No. Nutritionists universally recommend whole foods as the best fiber source, thanks to their broader nutritional benefits. Use prebiotic sodas only to supplement your fiber intake, not replace it.
Q: Are prebiotic sodas safe for everyone?
A: Most people can enjoy them in moderation, but those with IBS, IBD, or sensitive digestive systems should be cautious, as certain prebiotic fibers (e.g., inulin) can trigger bloating and discomfort.
Q: What makes prebiotic sodas different from probiotic sodas?
A: Prebiotic sodas supply fiber to feed gut bacteria. Probiotic sodas (e.g., some kefirs, kombucha) contain live microorganisms that can colonize your gut. Both aim to support gut health but do so differently.
Q: How often should I drink prebiotic soda?
A: There is no official guideline. Registered Dietitians recommend not exceeding one can a day, and only if your diet is fiber-poor. Whole foods should always be your primary source of prebiotic fiber.
Final Thoughts
Prebiotic sodas offer a flavorful, low-sugar way to supplement your fiber intake and support digestive health. However, nutrition experts emphasize that whole, plant-based foods remain the best choice for overall nutrient balance, fiber variety, and gut health benefits. For most people, occasional enjoyment of prebiotic soda can be part of a healthy lifestyle, but reliance on these beverages for fiber is not recommended. Always observe your body’s responses and consult a healthcare provider when making significant dietary changes.
