Prebiotic sodas went from health-store curiosity to checkout-aisle staple, and two brands own the category: Olipop and Poppi. They look similar, cost similar-ish, and both promise your gut a better life. We compared what’s actually in the cans — and what thousands of drinkers consistently report.

First look comparison: based on verified labels, pricing, and aggregated public reception. Our own side-by-side taste test is coming.

The formula face-off

This is where the two genuinely differ. Olipop runs 2–5g sugar per can with 9g of prebiotic fiber from chicory root, cassava, and Jerusalem artichoke. Poppi is typically 4–5g sugar with apple cider vinegar and about 2g of fiber. If fiber is your reason for buying, Olipop delivers roughly four times more of it.

The taste consensus

The pattern across drinker reviews is remarkably consistent: Olipop reads as the more soda-like of the two — its fiber blend gives it body and a creamy mouthfeel, and Vintage Cola is regularly described as passing for craft soda. Poppi reads lighter and juicier, closer to a flavored sparkling water with a splash of juice. The practical translation: people quitting regular soda tend to report Olipop scratches the itch; Poppi wins with people who found soda too heavy in the first place.

The gut-health reality check

Neither can is a medical intervention. The research on prebiotic fiber is promising, and Olipop’s 9g is a meaningful contribution toward the ~25g daily target most people miss. Poppi’s ACV dose is small enough that you shouldn’t expect much from it — treat both as “soda that’s better for you than soda,” not as a supplement.

Price

Poppi is consistently $4–6 cheaper per 12-pack and goes on sale more often. If budget decides it, Poppi takes the round.

Verdict

Buy Olipop if you want the most soda-like experience and the fiber payload — on the merits, it’s the stronger product. Buy Poppi if you prefer lighter, fruitier drinks or you’re buying for a crowd on a budget.
