Poppi is everywhere. The colorful cans line end-caps at Target, fill coolers at Whole Foods, and dominate the prebiotic soda section on Amazon. The brand landed a Super Bowl ad in 2024 and has been one of the fastest-growing beverage companies in the United States, projecting over $500 million in retail sales. With a roster of influencer endorsements and social media buzz that most beverage brands would kill for, Poppi has successfully positioned itself as the fun, accessible gateway to gut health.

But marketing momentum and actual health benefit are two very different things. Poppi's prebiotic claims have already faced legal scrutiny, and the central question remains: is a can of Poppi meaningfully different from any other low-sugar soda, or is this gut health theater?

We analyzed the full formula, dug into the research behind the key ingredient (apple cider vinegar), looked at the lawsuit, and scored Poppi against our standard criteria. Here's the honest assessment.

The Freak Score

Criteria Score Notes
Ingredient Quality 6/10 Apple cider vinegar is the functional core, supported by some research but at higher doses than what Poppi provides. Remaining ingredients are standard beverage components. No clinically validated prebiotic fibers at meaningful doses.
Dosing 4/10 1 tablespoon of ACV per can. Most ACV research uses 1-2 tablespoons daily, so one can is at the very bottom of studied ranges. Only 2g of prebiotic fiber -- well below the 5g minimum where prebiotic research shows effects. This is the score's biggest weakness.
Clean Formula 8/10 5g sugar per can is low. Sweetened with stevia and fruit juice. No artificial sweeteners, colors, or preservatives. Natural flavors present but expected. Clean ingredient list overall.
Transparency 6/10 Ingredient list is published and straightforward. However, the marketing leans heavily into "gut health" and "prebiotic" claims that the formula doesn't fully support at these doses. The gap between what's claimed and what's delivered drags this score down.
Third-Party Testing 4/10 No NSF, USP, or equivalent certification. No publicly available Certificates of Analysis. Non-GMO verified. Below our preferred standard, typical for the category.
Value 7/10 $22.99/12-pack ($1.92/can) is the most affordable prebiotic soda on the market. If you're comparing to Olipop ($3.00/can), Poppi offers better per-can economics. Whether the value proposition holds depends on what you think you're getting for the money.
Source & Manufacturing 6/10 Non-GMO. Ingredients are standard food-grade. Manufactured in the US. The ACV is described as "with the mother," but specific sourcing details (organic certification, ACV brand/supplier) are not prominently disclosed.
Overall 5.9/10 Weighted average. Poppi is a well-made, low-sugar soda that tastes great. As a gut health product, the dosing doesn't support the claims. It's a better choice than regular soda, but calling it a functional prebiotic beverage stretches the evidence.

A 5.9 reflects the fundamental tension in Poppi's positioning. The formula is clean and the product is enjoyable, but the prebiotic dosing is too low to deliver the gut health benefits the marketing implies. The score would be higher if the brand positioned itself as "a low-sugar soda with a touch of ACV" rather than a gut health solution.

What Is Poppi?

Poppi is a carbonated prebiotic soda made with apple cider vinegar, fruit juice, and cane sugar, sweetened with stevia. Each 12-ounce can contains 5 grams of sugar, 20 calories, and 1 tablespoon of apple cider vinegar "with the mother." The brand also claims 2 grams of prebiotic fiber per can from the apple cider vinegar and agave inulin.

Founded in 2018 by Allison and Stephen Ellsworth (originally under the name "Mother Beverage"), Poppi started on Shark Tank and has since raised significant venture capital to fuel its growth into a national brand. The company is available in 30,000+ retail locations and comes in 10+ flavors including Strawberry Lemon, Raspberry Rose, Doc Pop, and Classic Cola.

The pitch: a soda that supports gut health through apple cider vinegar's prebiotic properties, while tasting like something you'd actually enjoy drinking.

The Apple Cider Vinegar Question

Apple cider vinegar is Poppi's functional centerpiece, so let's evaluate the ingredient honestly.

ACV is vinegar made from fermented apple juice. "With the mother" means it contains the strand-like colonies of acetic acid bacteria and cellulose that form during fermentation -- a visual marker of an unfiltered, unrefined product. The "mother" contains some bacteria and enzymes, though whether these survive stomach acid in meaningful quantities is debatable.

What the Research Says About ACV

Blood sugar management: The most robust evidence for ACV relates to post-meal blood glucose. A 2004 study in Diabetes Care found that consuming 20g (about 4 teaspoons) of apple cider vinegar diluted in water before a high-carbohydrate meal improved insulin sensitivity by 19-34% in insulin-resistant participants and reduced post-meal blood glucose. A 2017 systematic review in Diabetes Research and Clinical Practice found similar modest blood sugar benefits across multiple studies. However, most studies used 1-2 tablespoons (15-30ml) of undiluted ACV, not ACV diluted in a 12-ounce soda.

Gut health: Here's where Poppi's claims get shaky. ACV contains acetic acid, which has some antimicrobial properties, and trace amounts of pectin (a prebiotic fiber from the apples). But there are no clinical trials demonstrating that 1 tablespoon of ACV in a carbonated beverage produces meaningful prebiotic effects or changes in gut microbiome composition. The "prebiotic" label leans on the presence of inulin and the theoretical properties of ACV, not on evidence that this specific product at this specific dose does anything measurable to your gut bacteria.

Weight management: Several studies have found modest associations between ACV consumption and reduced appetite or weight loss. A 2009 study in Bioscience, Biotechnology, and Biochemistry found that daily consumption of 15ml or 30ml of vinegar over 12 weeks was associated with reduced body weight, BMI, and visceral fat compared to placebo. Effects were modest (2-4 pounds over 3 months) and the vinegar doses were higher than what Poppi provides.

The dose problem: Poppi contains 1 tablespoon (15ml) of ACV per can. This is at the very bottom of the range studied in clinical research. The ACV is also diluted in 12 ounces of carbonated liquid with sugar, fruit juice, and stevia -- a very different delivery vehicle than the undiluted ACV-in-water used in most studies. Whether the functional effects translate at this dilution and dose is genuinely unknown, because no one has studied it.

The Lawsuit: What It Means

In 2023, a class-action lawsuit was filed against Poppi alleging that the brand's gut health marketing claims were misleading. The plaintiff argued that Poppi's prebiotic content -- primarily from 2 grams of agave inulin per can -- was too low to deliver the gut health benefits implied by the marketing.

The lawsuit cited research showing that prebiotic effects typically require 5 grams or more of prebiotic fiber daily, with most clinical studies using 12-20 grams. At 2 grams per can, a consumer would need to drink 3-6 cans of Poppi daily to reach the range where clinical evidence exists -- consuming 15-30 grams of sugar and spending $5.76-$11.52 in the process.

Poppi settled the lawsuit in 2024. The settlement didn't require the company to admit wrongdoing or change their marketing, but it highlighted a legitimate issue: there's a meaningful gap between what Poppi's branding implies and what the formula can reasonably deliver at a one-can-per-day consumption pattern.

Our take: The lawsuit was fair. Poppi's marketing strongly implies gut health benefits ("Be gut happy," "prebiotic soda") that the 2-gram fiber dose can't support based on the existing evidence. This isn't the same as saying Poppi is a bad product -- it's saying the marketing oversells what the formula delivers. A can of Poppi is a low-sugar soda with a tablespoon of ACV and a sprinkle of inulin. That's a fine product. It's not a gut health intervention.

Full Ingredient Breakdown

We'll use the Strawberry Lemon flavor as our reference.

Ingredient Dose Verdict Notes
Sparkling Water Base Neutral Standard carbonated water.
Apple Cider Vinegar 1 tbsp (15ml) Mixed "With the mother." Some evidence for blood sugar modulation at this dose when taken undiluted. Prebiotic benefit at this dose in this delivery format is unproven. Not harmful, but the gut health benefit is overstated.
Cane Sugar Part of 5g total Neutral Contributes a portion of the 5g sugar per can. Preferable to high-fructose corn syrup. Reasonable amount for a soda.
Agave Inulin Part of 2g fiber Mixed Prebiotic fiber from agave. 2g is a meaningful ingredient but below the 5g threshold where prebiotic research typically shows effects. Would need to drink multiple cans daily to reach clinically studied doses.
Fruit Juice (from concentrate) Small amount Neutral Provides natural flavor and color. Minimal nutritional significance at this quantity. Varies by flavor (strawberry, lemon, apple, etc.).
Apple Juice (from concentrate) Small amount Neutral Natural sweetener and flavoring. Standard beverage ingredient.
Stevia Leaf Extract -- Good Zero-calorie natural sweetener. Well-studied safety profile. No meaningful impact on gut microbiome or blood sugar.
Natural Flavors -- Neutral FDA-regulated flavoring agents from natural sources. Standard in the beverage industry. Vague by definition.
Citric Acid -- Neutral Natural acidity regulator. Found in citrus fruits. No concerns at beverage concentrations.
Lemon Juice Concentrate Small amount Neutral Natural flavoring and mild preservative. No concerns.

The 2 Grams of Fiber in Context

Let's put Poppi's fiber content in perspective:

  • Daily recommended fiber intake: 25-38g per day (most Americans get 10-15g)
  • Poppi per can: 2g (5-8% of daily recommendation)
  • Olipop per can: 9g (24-36% of daily recommendation)
  • Clinical prebiotic dose range: 5-20g daily
  • Regular Coca-Cola: 0g

Two grams of prebiotic fiber isn't nothing. It's the amount of fiber in about 3 almonds or half a small banana. It contributes to your daily total, but calling it a "prebiotic dose" stretches the definition. Olipop delivers 4.5x more fiber per can. A single medium apple delivers 4.4g of fiber -- more than two cans of Poppi -- for about $1.

Poppi vs. Olipop: The Comparison You're Here For

These two brands own the prebiotic soda category, and they're often compared head-to-head. Here's how they stack up:

Feature Poppi Olipop
Price/can $1.92 ~$3.00
Sugar 5g 2-5g
Fiber 2g 9g
Calories 20-25 35-50
Functional ingredient ACV (1 tbsp) OLISMART blend (9 prebiotic fibers + botanicals)
Prebiotic sources Agave inulin (single source) Chicory root inulin, cassava fiber, Jerusalem artichoke inulin (multiple sources)
Non-GMO Yes Yes
Our Freak Score 5.9/10 7.6/10
Class-action lawsuit Yes (settled) Yes (filed)

The short version: If gut health is your primary motivation, Olipop is the significantly better product. 9g of diverse prebiotic fiber versus 2g of agave inulin is not a close comparison. If price is your primary concern and you want a low-sugar soda that tastes good, Poppi delivers at a lower cost per can.

Neither product is a substitute for eating actual fiber-rich foods. Both are better than regular soda.

How We'd Use It

As a soda replacement: This is where Poppi genuinely shines. If your current habit is a can of Coca-Cola (39g sugar, 140 calories), switching to Poppi (5g sugar, 20 calories) is an unambiguous improvement. Don't overthink the prebiotic angle -- the sugar reduction alone makes it a meaningful dietary upgrade.

Quantity: 1-2 cans per day is reasonable from a sugar and calorie standpoint. Drinking more than that for the "prebiotic benefit" is a bad trade -- you'd get more prebiotic fiber from a banana and save money.

What to pair it with: If you're genuinely interested in gut health, drink your Poppi AND eat prebiotic-rich whole foods: onions, garlic, bananas, asparagus, oats, and legumes. The can of Poppi is a nice complement, not a replacement.

What it isn't: A gut health solution. A probiotic supplement. A meaningful prebiotic intervention. It's a low-sugar soda with ACV. Enjoy it as such.

Flavor Notes

We tried the full lineup. Brief notes:

  • Strawberry Lemon: The bestseller. Bright, fruity, crowd-pleasing. 8/10.
  • Raspberry Rose: Floral and unique. The most "sophisticated" option. 7/10.
  • Doc Pop: The Dr. Pepper competitor. Surprisingly good. 8/10.
  • Orange: Clean and citrusy. Simple and refreshing. 7/10.
  • Classic Cola: Not as good as Olipop's Vintage Cola, but respectable. 6/10.
  • Grape: Tastes like grape soda. That's the compliment and the criticism. 6/10.
  • Watermelon: Sweet and summery. Good for hot days. 7/10.
  • Cherry Limeade: Tart and bright. Among the best in the lineup. 8/10.
  • Ginger Lime: Mild ginger flavor with good lime. 7/10.
  • Root Beer: Decent but thin compared to Olipop's root beer. 6/10.

The flavor quality is Poppi's genuine strength. These taste like well-made sodas, not like health food. The texture is lighter than conventional soda (no high-fructose corn syrup thickness), which some people prefer and others miss.

Who Should Buy Poppi

Buy Poppi if:

  • You drink regular soda and want a lower-sugar alternative that tastes great
  • You want an affordable prebiotic soda ($1.92/can vs. $3.00 for Olipop)
  • You like the flavor of apple cider vinegar-based drinks
  • You want a clean-ingredient soda for casual consumption
  • You understand it's a low-sugar soda, not a gut health product

Don't buy Poppi if:

  • You're specifically looking for meaningful prebiotic fiber (buy Olipop instead)
  • You expect the gut health benefits the marketing implies
  • You're ACV-sensitive (some people experience reflux from apple cider vinegar)
  • You're comparing it to whole foods for gut health value -- an apple and a glass of water will give you more fiber for less money

Frequently Asked Questions

Does Poppi actually help with gut health?

Based on the evidence, the gut health benefit is minimal at one can per day. The 2g of agave inulin is below the threshold where prebiotic research shows meaningful effects (typically 5g+ daily). The ACV "with the mother" may provide trace beneficial bacteria, but whether these survive stomach acid and meaningfully affect your microbiome is unproven. Poppi is a better choice than regular soda, but the gut health marketing overpromises relative to what the formula can deliver.

Is the apple cider vinegar in Poppi enough to matter?

One tablespoon of ACV is at the very bottom of the range studied in clinical research. Some blood sugar studies used 1-2 tablespoons of undiluted ACV and found modest effects. But Poppi's ACV is diluted in 12 ounces of carbonated liquid, and no studies have specifically tested ACV at this dilution and format. It's not harmful, and it may provide marginal benefit, but it's not the therapeutic dose implied by the marketing.

Why is Poppi cheaper than Olipop?

Poppi's formula is simpler and less expensive to produce. Apple cider vinegar and agave inulin are low-cost ingredients compared to Olipop's nine-ingredient OLISMART blend. Poppi also contains less prebiotic fiber (2g vs. 9g), which reduces ingredient cost per can. The price difference reflects a genuine difference in formulation complexity.

Is Poppi safe to drink every day?

Yes, for most people. The sugar (5g), calorie (20), and ACV (1 tbsp) content per can are all within reasonable daily consumption ranges. People with GERD or acid reflux should be cautious, as ACV can exacerbate symptoms. If you experience stomach discomfort after drinking Poppi, the acidity may not agree with your digestive system.

Did the lawsuit prove Poppi is a scam?

No. The lawsuit alleged that Poppi's gut health marketing claims were misleading given the low prebiotic fiber content -- not that the product was unsafe or contained undisclosed ingredients. Poppi settled without admitting wrongdoing. The product itself is a legitimate, well-made, low-sugar soda. The issue was that the marketing implied a level of gut health benefit that the 2g fiber dose can't substantiate based on the current evidence.

How does Poppi compare to just drinking apple cider vinegar?

A tablespoon of Bragg's ACV costs about $0.15. A can of Poppi costs $1.92. You're paying $1.77 for carbonation, flavor, stevia, a nice can, and the social acceptability of not being the person chugging vinegar from a bottle. Whether that premium is worth it depends entirely on your priorities.
