The Prebiotic Soda Boom: We Compared Leading Store-Bought Brands on Sugar and Flavor

Prebiotic sodas have moved from niche wellness shelves to mainstream supermarket fridges, with Coca-Cola and Pepsi now competing alongside category pioneers Olipop and Poppi. Here’s how the major brands stack up on sugar, fiber, flavor and what’s actually inside the can.

What are the most popular prebiotic sodas at the store right now?

The category is led by Olipop and Poppi, but Coca-Cola’s Simply Pop, Pepsi Prebiotic Cola, SunSip and Daytrip have all entered the space as functional beverages move further into the mainstream.

Olipop is one of the original leaders, known for higher fiber content and classic soda-style flavors like Root Beer and Vintage Cola, with about 2 to 5 grams of sugar per can. Poppi, its main competitor, is positioned as a low-sugar gut-healthy soda with prebiotics like agave inulin and apple cider vinegar, also at around 4 to 5 grams of sugar per can.

Pepsi Prebiotic Cola comes in Original Cola and Cherry Vanilla, with about 5 grams of sugar per can, designed to closely mimic the taste of traditional cola while adding prebiotic fiber. Simply Pop, Coca-Cola’s entry, is made with real fruit juice and added prebiotic fiber, and contains roughly 3 to 6 grams of sugar per can depending on the flavor.

SunSip is a newer functional soda brand built around prebiotics, plant-based ingredients and lower sugar, often sold in wellness and natural grocery stores at around 2 to 6 grams of sugar per can. Daytrip rounds out the lineup as a USDA organic prebiotic soda with vitamin C and lower sugar — typically 3 to 7 grams per can, often from organic fruit juice and added sweeteners.

For shoppers comparing the field, the differences come down to fiber content, sweetener type, juice percentage and how closely the drink mimics traditional soda versus a fruit-forward functional beverage. Sugar levels are similar across the category; the real differentiators are fiber and what’s doing the sweetening.

How do Olipop and Poppi compare on sugar and fiber?

Olipop and Poppi both market themselves as low-sugar prebiotic alternatives to traditional soda, but they differ meaningfully in fiber content, sweeteners and taste profile.

Olipop contains roughly 2 to 5 grams of sugar per can and is known for its higher fiber content — one of its main selling points in the category. According to Alaina Chou writing for Bon Appetit, “Olipop’s impressive fiber content is one of its main draws over similar brands in the space, but it’s also one of the best-tasting prebiotic sodas in my personal opinion.” She also notes that Olipop is not sweetened with monk fruit, which she avoids because of its aftertaste.

Poppi, by contrast, contains about 4 to 5 grams of sugar per can and uses prebiotics like agave inulin and apple cider vinegar. It tends to taste brighter, fruitier and slightly more tart than Olipop, with a faint vinegar note underneath. Of Poppi, Chou writes: “Poppi has an ever so slightly tangy aftertaste thanks to the included apple cider vinegar—it’s faint, but it’s there. And with only three grams of fiber, it’s not a great source of prebiotics.”

Olipop offers nearly 20 flavors, including options like Strawberry Vanilla, Cream Soda and Tropical Punch — Chou’s personal favorites — alongside traditional soda-style options like Root Beer and Vintage Cola. That makes it a closer match for shoppers transitioning away from regular soda. Chou recommends Olipop specifically for “traditional soda lovers looking to make the switch.”

The bottom line: if fiber content and a classic soda profile matter most, Olipop edges ahead. If you prefer a brighter, fruitier drink and don’t mind the apple cider vinegar note, Poppi delivers on that.

Is Coca-Cola’s Simply Pop a good prebiotic soda?

Simply Pop is Coca-Cola’s entry into the prebiotic soda space, made with real fruit juice and added prebiotic fiber, with about 3 to 6 grams of sugar per can depending on the flavor and juice content.

Each 12-ounce can contains 6 grams of prebiotic fiber, plus a dose of vitamin C and zinc, which the brand claims helps “support immune function,” according to Sara Klimeck writing for Tasting Table. The cans are made without any added sugar and contain about 25 to 30% fruit juice from concentrate.

Klimeck writes: “Simply Pop positions itself as a beverage that offers all the benefits of a health drink, but with the sipping experience of a soda. Each 12-ounce can of its soda contains 6 grams of prebiotic fiber, as well as a dose of vitamin C and zinc, which the brand claims helps to ‘support immune function.’ The cans are made without any added sugar and contain about 25 to 30% fruit juice from concentrate — a statistic that Coca-Cola notes on its website as being ‘a first for [this] fast-growing segment.’ In comparison, its competitor, Poppi, uses between 3% and 6% juice in its fruity sodas.”

That higher juice content is the key differentiator: Simply Pop sits closer to a juice-forward functional beverage than to a traditional soda. Flavors include Strawberry, Pineapple Mango, Fruit Punch, Citrus Punch, Lime and Raspberry — a fruit-forward lineup rather than a cola-style one.

For shoppers prioritizing real fruit juice and added vitamins alongside prebiotic fiber, Simply Pop offers something distinct from the cola-mimicking Pepsi Prebiotic and the fizzier, lower-juice profiles of Olipop and Poppi.

What do Pepsi Prebiotic Cola, SunSip and Daytrip offer?

Pepsi Prebiotic Cola, SunSip and Daytrip each take a different approach to the category, with sugar contents ranging from about 2 to 7 grams per can depending on the brand and flavor.

Pepsi Prebiotic Cola comes in two flavors — Original Cola and Cherry Vanilla — with about 5 grams of sugar per can. It is designed to closely mimic the taste of traditional cola while adding prebiotic fiber, making it the closest match in the category for drinkers loyal to a classic cola profile.

SunSip is a newer functional soda brand positioned around prebiotics, plant-based ingredients and lower sugar, typically marketed in wellness and natural grocery stores. Sugar runs about 2 to 6 grams per can, often on the lower end depending on the flavor. SunSip’s lineup includes Ginger, Lemon Lime, a cola-style option and fruit-forward seasonal flavors, giving shoppers a mix of traditional and rotating choices.

Daytrip rounds out the field as a USDA organic prebiotic soda with vitamin C and lower sugar — about 3 to 7 grams per can, often from organic fruit juice and added sweeteners. Daytrip’s flavors include Strawberry, Peach Mango and Raspberry Lime, focusing on fruit-forward, juice-influenced profiles rather than cola-style options.

For shoppers comparing across brands, the choice often comes down to whether you want a cola substitute like Pepsi Prebiotic or Olipop’s Vintage Cola, a fruit-forward functional drink like Simply Pop or Daytrip, or a wellness-focused alternative like SunSip. Sugar content varies less than fiber content, sweetener choice and juice percentage — which are the real differentiators inside the can.
