Olipop vs Poppi (2026): Fiber, Taste, Lawsuit & Which to Buy

Olipop vs Poppi (2026): Fiber, Taste, Lawsuit & Which to Buy

The short version: Olipop and Poppi look like twins on the shelf, but they’re built differently where it counts. Olipop delivers up to 9 grams of prebiotic fiber per can — Poppi delivers 2. Poppi settled an $8.9 million class-action lawsuit over its gut-health marketing; Olipop hasn’t faced one. Poppi is now owned by PepsiCo; Olipop remains independent. If you’re buying for gut health, Olipop wins clearly. If you’re buying for taste and a lighter, juicier drink, Poppi has a real case.

The Head-to-Head Table

The Fiber Gap Is the Whole Ballgame

A can of Olipop’s refrigerated line contains up to 9 grams of fiber — from a blend of cassava root fiber, chicory inulin, and Jerusalem artichoke inulin plus botanicals. Nine grams is enough fiber to be noticeable. Research on inulin-type fibers generally uses daily doses in the 5–10g range — meaning one Olipop actually lands inside the range studied for prebiotic effects.

Poppi contains 2 grams, primarily from agave inulin. Two grams isn’t nothing, but it’s below the doses associated with measurable prebiotic benefit in most research — and that gap is exactly what landed Poppi in court.

The $8.9 Million Lawsuit, Briefly

In June 2024, a class-action lawsuit alleged that Poppi’s “Be Gut Happy. Be Gut Healthy.” marketing overstated what 2 grams of fiber can do. Poppi denied wrongdoing but settled for $8.9 million in 2025, agreeing to adjust its advertising. Months earlier, PepsiCo had acquired the brand for $1.95 billion.

Taste: The Real Tiebreaker

Olipop tastes like soda. Fuller-bodied, creamier, more “classic soda shop.” Vintage Cola genuinely reads as a cola; Cream Soda and Root Beer are the standouts. The fiber blend gives it a slightly thicker mouthfeel. If you’re quitting Coke or Dr Pepper, Olipop is the closer match.

Poppi tastes like sparkling juice. Lighter, brighter, fruit-forward, with a faint tang from the apple cider vinegar. Strawberry Lemon and Cherry Limeade are the crowd favorites. If your old habit was Sprite or fruit sodas, Poppi is the closer match.

A useful rule: dark-soda people prefer Olipop; fruit-soda people prefer Poppi. Your old habit predicts your new favorite.

The Practical Differences

Digestive adjustment. Olipop’s 9 grams of fiber is a real dose. Start with half a can and let your system adjust. Poppi’s 2 grams rarely causes any adjustment issues.

Price and availability. Poppi typically runs 15–25% cheaper per can and, with PepsiCo’s distribution muscle, is increasingly everywhere. Olipop costs more but has near-total grocery penetration.

So Which Should You Buy?

Buy Olipop if: gut health is your actual reason for buying, you’re replacing a dark-soda habit, or you want the fuller classic-soda taste.

Buy Poppi if: you’re replacing fruity sodas or juice, you want fewer calories and a lighter drink, or price matters and you’re buying in volume.

Buy both if: you’re using them as the bridge that makes leaving regular soda painless. Either one cuts your per-can sugar by about 90% versus a Coke.
