Store-Bought Prebiotic Sodas Explained: How They Compare on Sugar, Fiber and Taste

The soda aisle is changing fast. What started as a niche wellness category dominated by Olipop and Poppi has now drawn in the biggest names in beverages, with Pepsi launching its own prebiotic cola and Coca-Cola entering the space with Simply Pop. For shoppers trying to cut sugar without giving up fizz, the choices — and the marketing claims — are multiplying.

Here’s how the leading store-bought prebiotic sodas stack up on sugar, fiber and flavor, and what reviewers are saying about each.

How prebiotic sodas differ from regular soda

Prebiotic sodas are marketed as “functional beverages”: carbonated drinks that include added prebiotic fiber, often alongside lower sugar content than traditional soda. Brands typically use ingredients like agave inulin, apple cider vinegar or fruit juice to deliver flavor while keeping sugar grams in the single digits per can.

The category leans on gut-health messaging, but fiber content varies widely between brands — and so does taste.

Olipop and Poppi: the brands that built the category

Olipop has helped define the space, with classic soda-style flavors like Root Beer and Vintage Cola and roughly 2 to 5 grams of sugar per can. It’s known for higher fiber content than most competitors.

Alaina Chou, writing for Bon Appétit, called it a strong starting point for traditional soda drinkers: “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.” Her favorites among the roughly 20 flavors are Strawberry Vanilla, Cream Soda and Tropical Punch.

Poppi, Olipop’s main competitor, runs about 4 to 5 grams of sugar per can and uses agave inulin and apple cider vinegar. The flavor profile leans brighter, fruitier and slightly more tart.

Chou noted the trade-off: “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.”

Why Pepsi and Coca-Cola jumped into prebiotic soda

The biggest shift in the category is the entry of legacy soda giants.

Pepsi Prebiotic Cola comes in Original Cola and Cherry Vanilla, with about 5 grams of sugar per can. It’s designed to closely mimic the taste of traditional cola while adding prebiotic fiber.

Simply Pop, from Coca-Cola, is built around real fruit juice and added prebiotic fiber, with sugar ranging from about 3 to 6 grams per can depending on flavor. Available flavors include Strawberry, Pineapple Mango, Fruit Punch, Citrus Punch, Lime and Raspberry.

Sara Klimeck, writing for Tasting Table, described how the brand is positioning itself: “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.’”

She added that the cans contain no added sugar and roughly 25% to 30% fruit juice from concentrate, compared with the 3% to 6% juice Poppi uses in its fruity sodas.

Smaller brands worth knowing: SunSip and Daytrip

Beyond the household names, smaller functional-soda brands are carving out shelf space in wellness and natural grocery aisles.

SunSip runs about 2 to 6 grams of sugar per can, often on the lower end depending on flavor. It’s positioned around prebiotics, plant-based ingredients and lower sugar, with options including Ginger, Lemon Lime, a cola-style drink and fruit-forward seasonal flavors.

Daytrip is a USDA-organic prebiotic soda with added vitamin C and roughly 3 to 7 grams of sugar per can, often coming from organic fruit juice and sweeteners. Flavors include Strawberry, Peach Mango and Raspberry Lime.

What to consider when choosing a prebiotic soda

Sugar content, fiber content and sweetener type are the three biggest variables across the category. Olipop leads on fiber. Poppi and Daytrip lean fruitier. Pepsi Prebiotic Cola and Simply Pop bring familiar mainstream taste with the functional add-ins. SunSip targets the natural-grocery shopper.

For drinkers making the switch from traditional soda, the choice often comes down to whether you want something that tastes like classic cola — or something closer to a flavored sparkling juice.
