Core Ingredient Philosophy: ACV vs. Plant Fibers
At the heart of the difference between Poppi and Olipop lies their core functional ingredients, which dictate much of their nutritional content and taste profile.
Poppi's Apple Cider Vinegar Approach
Poppi was founded on the potential health benefits of apple cider vinegar (ACV), specifically its purported ability to aid digestion and help stabilize blood sugar levels. The founders, Allison and Stephen Ellsworth, created the soda as a more palatable way to consume ACV without the strong, acidic taste.
- Agave Inulin: Poppi gets its prebiotic fiber from agave inulin and cassava root fiber.
- Apple Cider Vinegar: A small amount of unfiltered ACV is included in every can.
- Targeted Benefits: The brand focuses on the general wellness benefits associated with ACV, like gut health and improved digestion.
Olipop's Varied Botanical Blend
In contrast, Olipop is built around a proprietary blend of botanicals and plant-based fibers called OLISMART. The company worked with microbiome research pioneers to develop a formula focused on fostering a healthy gut microbiome.
- Diverse Fibers: Olipop includes a more varied and higher quantity of prebiotic fiber from sources such as chicory root, Jerusalem artichoke, and kudzu root.
- Botanicals: Additional ingredients like marshmallow root and calendula flower are also present.
- Research-Backed Claims: Olipop’s approach is marketed with more emphasis on the scientific backing for its gut-health-supporting ingredients.
Nutritional Breakdown: Calories, Sugar, and Fiber
When comparing the nutritional content, both brands offer significant improvements over traditional sugary sodas. However, their specific macros differ, which is an important consideration depending on your dietary goals.
Comparison Table: Poppi vs. Olipop (Average per 12 oz can)
| Feature | Poppi | Olipop | 
|---|---|---|
| Calories | ~25 kcal | ~35-50 kcal | 
| Sugar | ~5g or less | 2-5g | 
| Fiber | ~2g | ~9g | 
| Key Functional Ingredient | Apple Cider Vinegar | Varied Plant Fibers (OLISMART) | 
| Sweetener | Organic Cane Sugar, Stevia | Cassava Root Syrup, Stevia | 
Flavor Profile and Sweetness: Tangy vs. Nostalgic
The final, and perhaps most subjective, difference between the two is the taste. This is where personal preference truly plays the biggest role.
- Poppi Flavor: With apple cider vinegar as a central ingredient, Poppi often features a more fruit-forward, slightly tangy flavor profile. The taste is often described as crisp and refreshing, and many reviews suggest it has a smoother, more balanced sweetness that is not overly cloying.
- Olipop Flavor: Olipop focuses on replicating nostalgic soda flavors like Vintage Cola and Classic Root Beer, and generally offers a sweeter, sometimes creamier mouthfeel. However, some reviewers note that certain flavors can have a slightly saccharine, candy-like or medicinal aftertaste.
Health Claims and Efficacy: What to Expect
While both brands market themselves as promoting gut health, the efficacy and transparency of these claims have been subjects of debate and even legal action.
Challenges to Poppi’s Claims
A class-action lawsuit filed in 2024 challenged Poppi's marketing, alleging that the 2 grams of prebiotic fiber in each can is not enough to provide the meaningful gut health benefits advertised. The suit suggests that a person would need to consume multiple cans a day to see effects, which could undermine the low-sugar benefits.
Olipop’s Fiber Advantage
Olipop’s higher fiber content (around 9 grams per can) puts it in a stronger position to deliver the benefits of prebiotic fiber. However, nutrition experts still point out that these sodas should not be a sole source of fiber and that a balanced, fiber-rich diet is more beneficial for long-term digestive health.
Conclusion: Which is Right for You?
Both Poppi and Olipop offer healthier, low-sugar alternatives to traditional soda, but cater to slightly different preferences and health goals. Your final decision may come down to what you prioritize in a functional beverage.
If you prefer a crisp, fruity flavor profile with a subtle tang and are focused on the benefits of apple cider vinegar, Poppi is likely the better choice. If your main goal is to significantly increase prebiotic fiber intake in a drink that resembles classic soda flavors, Olipop, with its higher fiber content and varied botanical blend, may be more appealing. Ultimately, both represent a step toward healthier beverage choices for consumers. For more information on the brands and their health claims, you can visit their respective websites.
