If you’re trying to break up with Coke, Dr Pepper, or your 3pm Diet Coke habit, two cans keep showing up in every “I quit soda” video: Olipop and Poppi. They’re the faces of the “modern soda” movement — fizzy, nostalgic, and promising gut-health benefits instead of 39 grams of sugar.
But they’re not the same drink. They’re built on different ingredients, hit different flavor notes, and suit different kinds of soda quitters. I’ve tasted both lineups end to end. Here’s the honest head-to-head.
The 10-second answer: Choose Olipop if you want the closest replacement for a real cola or root beer and care most about fiber. Choose Poppi if you want a lighter, fruitier, more “sparkling” experience and like the tang of apple cider vinegar. Both beat regular soda by a mile.
The quick verdict
| Olipop | Poppi | |
|---|---|---|
| Best for | Hardcore cola/root beer cravers | Fruit-soda & seltzer lovers |
| Sugar | 2–5g | <5g |
| Calories | 35–50 | 20–25 |
| Prebiotic fiber | ~9g (chicory root, cassava, Jerusalem artichoke) | ~2g (agave inulin) |
| Signature ingredient | OLISMART fiber blend | Apple cider vinegar |
| Flavor style | Rich, “real soda” body | Light, crisp, fruity |
| Typical price | ~$2.49/can | ~$2.49/can |
What’s actually in each one
Olipop
Olipop leads with fiber. Each can packs around 9 grams of prebiotic plant fiber from chicory root, cassava root, and Jerusalem artichoke, plus botanicals — all for 2–5g of sugar and under 50 calories. The texture is noticeably fuller than a seltzer; it genuinely drinks like soda, which is why its cola and root beer flavors are the ones people cite when they say “I don’t even miss Coke anymore.”
Poppi
Poppi is built around apple cider vinegar and real fruit juice, with less than 5g of sugar and roughly 20–25 calories per can. It carries a smaller dose of prebiotic fiber (about 2g of agave inulin). The result is lighter and brighter — closer to a flavored sparkling water with a fruity kick than to a heavy cola.
The honest fiber note: Olipop’s ~9g of fiber is a real differentiator, but ramp up slowly — a sudden jump in fiber can cause bloating or gas for some people. Poppi’s lower fiber means it’s gentler on a sensitive stomach.
Taste test: how they actually drink
Olipop wins on replacement realism. Vintage Cola, Classic Root Beer, and Cherry Vanilla are the closest things I’ve found to the real sugary versions. If your goal is to trick your brain out of a Coke habit, Olipop is the stronger crutch.
Poppi wins on refreshment. Cherry Limeade, Raspberry Rose, and Watermelon are crisp and easy-drinking — better as an all-day sipper or a sparkling-water upgrade than as a cola stand-in.
Are they actually healthy? The honest answer
Both are dramatically better than regular soda — a single can of Coca-Cola has 39g of sugar, enough to blow past your entire daily recommended limit. Swapping to either of these takes you from ~39g to under 5g. That alone is a win for your teeth, your energy, and your waistline.
But two honesty checks:
- “Gut health” claims have limits. In 2025, Poppi settled a class-action lawsuit (~$8.9M) over how strongly it marketed gut-health benefits. The takeaway isn’t “Poppi is bad” — it’s that a single can won’t transform your microbiome. Treat these as a much better soda, not a supplement.
- They’re not water. The healthiest swap is still water or plain sparkling water. Olipop and Poppi are best used as the bridge that gets you off the hard stuff — not necessarily a forever 4-cans-a-day habit.
So which should you actually buy?
- Quitting cola/Dr Pepper/root beer? → Olipop. It’s the better replacement.
- Quitting Sprite, juice, or just want a healthier fizzy drink? → Poppi. It’s the better refresher.
- Honestly? Keep both in the fridge. Olipop for the “I really want a Coke” moments, Poppi for everyday sipping. The combo is what gets most people fully off regular soda.
