Comparing Prebiotic Sodas: The Fiber Facts
In the growing market of functional beverages, prebiotic sodas like Olipop and Poppi have carved out a significant niche. These drinks are often marketed as healthier alternatives to traditional sugary sodas, promising gut-health benefits. At the heart of these claims lies prebiotic fiber, a type of non-digestible fiber that feeds the beneficial bacteria in your gut. While both brands contain prebiotic fiber, there are major differences in the quantity and type, which directly impacts their nutritional profiles.
Olipop: The Higher-Fiber Option
Olipop is particularly known for its high fiber content and uses a proprietary blend called 'OLISMART'. This blend typically provides 6 to 9 grams of dietary fiber per 12-ounce can, depending on the flavor.
- Fiber Sources: Olipop's blend features multiple plant-based sources, including chicory root inulin, Jerusalem artichoke inulin, kudzu root, and cassava root fiber. This varied approach offers a wider spectrum of prebiotics compared to many competitors.
- Overall Nutrition: In addition to fiber, Olipop is low in sugar, containing 2–5 grams per can, and has a calorie count typically under 50 calories. It is also made with natural botanicals and without artificial sweeteners, flavors, or preservatives.
- Flavor Profile: The inclusion of botanicals and a higher fiber content gives Olipop a distinct mouthfeel and flavor. It is often described as having a richer, creamier texture compared to Poppi.
Poppi: The Lower-Fiber Alternative
Poppi also incorporates prebiotic fiber but in a much lower quantity per serving. For most flavors, a can of Poppi contains only 2 to 3 grams of dietary fiber.
- Fiber Source: The main prebiotic fiber in Poppi is agave inulin. While a valid prebiotic, the amount per can has been questioned regarding its ability to deliver significant gut health benefits, and was even a point of contention in a 2024 lawsuit against the company.
- Overall Nutrition: Poppi's calorie count is generally lower than Olipop's, with most flavors containing 25 calories or less per can. Poppi also features apple cider vinegar (ACV) as a key ingredient, which is associated with various health claims, though the amount per serving is small.
- Flavor Profile: Poppi's taste is often perceived as lighter and more fruit-forward than Olipop, with a slight tangy kick from the ACV.
Olipop vs. Poppi Comparison Table
| Feature | Olipop | Poppi | Winner (for Fiber) |
|---|---|---|---|
| Fiber Content (per can) | 6-9g | 2-3g | Olipop |
| Primary Fiber Source | OLISMART blend (chicory root inulin, cassava fiber, etc.) | Agave inulin | Olipop (for quantity and variety) |
| Key Functional Ingredient | Plant-based botanicals and fibers | Apple cider vinegar (ACV) | Tie (depends on desired benefit) |
| Calories (per can) | 35-50 calories | 20-30 calories | Poppi |
| Added Sugar (per can) | 1-4g | 3-5g | Olipop |
| Flavor Profile | Richer, creamier, often nostalgic | Lighter, fruitier, tangy kick | Tie (preference) |
Beyond the Numbers: Making an Informed Choice
When deciding between these two brands, your choice extends beyond just the fiber count. Both offer low-sugar, low-calorie alternatives to traditional sodas, making them a step up for many consumers. However, the health claims surrounding both products have been debated.
For instance, while Poppi contains fiber, dietitians have noted that the 2-3 grams per can may not be enough to provide meaningful gut health benefits, especially when compared to dietary guidelines and clinical study doses. Some consumers also report that the high fiber content in Olipop, particularly the inulin, can cause digestive discomfort such as bloating or gas, especially for those with sensitive stomachs or conditions like IBS. It's recommended to introduce these beverages slowly into your diet to assess your tolerance.
Consider your primary health goals. If maximizing prebiotic fiber intake from a beverage is your priority, Olipop is the clear winner. If you prefer a lower calorie count and a different flavor profile, and view the prebiotic content as a bonus rather than the main feature, then Poppi might be a better fit. Remember that prebiotic sodas should complement, not replace, a balanced diet rich in whole foods like fruits, vegetables, and legumes, which are the best natural sources of fiber.

Conclusion
In summary, both Olipop and Poppi contain fiber, but Olipop provides a significantly higher amount per can (6-9g vs. 2-3g). Olipop uses a more diverse blend of plant fibers, while Poppi primarily relies on agave inulin and includes apple cider vinegar. While both serve as healthier, low-sugar alternatives to conventional sodas, those prioritizing fiber for gut health will likely find Olipop more potent. Ultimately, personal taste and tolerance for fiber will dictate the best choice for you. It's a matter of weighing a greater fiber boost against other factors like calorie count, flavor, and digestive sensitivity.
