This article describes two class action complaints. The statements below are unproven allegations. Chobani, LLC has not been found liable, there is no certified class, and there is nothing to claim at this time. This page is informational and is not legal advice.

What Are These Lawsuits About?

Chobani, LLC is now facing two proposed class actions in the U.S. District Court for the Southern District of New York over how much protein its 32-ounce "20G Protein" Greek yogurt tubs actually deliver per serving. The first, Knox v. Chobani, LLC, No. 1:26-cv-05093-VEC, was filed June 16, 2026. The second, Lombardo v. Chobani, LLC, No. 1:26-cv-07408, was filed August 31, 2026. Neither is a settlement: there is no fund, no administrator, no claim form and no deadline.

Both complaints allege that consumers bought the 32-ounce tubs in reliance on the "20 grams of protein per serving" representation and would not have paid the same price had the per-serving figure been stated as the plaintiffs say the rules require. Chobani has not been found liable in either case.

The complaint does not allege that Chobani's yogurt is contaminated or unsafe. Instead, it raises a narrower, technical claim: that Chobani declares an inflated "serving size" on the 32-ounce multi-serving tub, and that the inflated serving is what lets the product display 20 grams of protein per serving rather than the roughly 18 grams the plaintiff says a correctly calculated serving would show. These are allegations only; Chobani has not yet responded in court, and nothing has been proven.

A Second Class Action Landed August 31, 2026

The August filing, Lombardo v. Chobani, LLC, No. 1:26-cv-07408, was brought in the same court by two consumers — one in Florida, one in New York — who allege they bought the 32-ounce tubs. Its plaintiffs also filed a statement of relatedness, the procedural step that flags a newly filed case as related to an earlier one. Whether the two cases are treated as related, assigned to the same judge, or consolidated is a decision for the court, and no such ruling has been reported.

The second complaint runs on the same core allegation — that the FDA's 170-gram reference amount for yogurt does not convert to the 3/4-cup, 190-gram serving Chobani declares on the 32-ounce tub — but it describes the rounding step differently. The June complaint alleges the correct serving is 1/2 cup at about 168.9 grams; the August complaint alleges it is 2/3 cup at about 169 grams. Both arrive at roughly 17.8 grams of protein per serving rather than 20. Each figure is the respective plaintiffs' calculation, not a court finding, and Chobani has not answered either complaint.

The claims are broader in the second case. Alongside New York General Business Law sections 349 and 350, it pleads counts under the Florida Deceptive and Unfair Trade Practices Act and Florida's false advertising statute, Fla. Stat. section 817.41, plus a nationwide unjust enrichment count. It proposes a nationwide class of 32-ounce purchasers with separate New York and Florida subclasses, and asks the court to order Chobani either to change the labeling or to reformulate the product so that a properly calculated serving does contain 20 grams.

The August complaint also spends more time on why two grams would matter. It alleges that 20 grams has become a consumer threshold for protein purchases, citing a 2024 International Food Information Council survey finding 71 percent of American consumers were trying to eat more protein, Chobani's own December 2024 survey reporting that 85 percent of Americans wanted to increase their protein intake, and market research indicating a high-protein claim can carry a price premium of up to 12 percent. It further alleges that the difference matters most to consumers limiting calories while trying to maximize protein. Those characterizations are drawn from the complaint and the sources it cites.

The Serving-Size Math at the Heart of the Case

Both cases turn on how the per-serving protein figure is calculated. The walk-through below follows the June complaint, which sets the math out in the most detail. Under FDA rules, the amount of a food "customarily consumed" in one sitting — the reference amount, or RACC — is 170 grams for yogurt. For a multi-serving container, a manufacturer is supposed to convert that reference amount into a household measure (cups, for yogurt), round it to the nearest standard increment, and use the rounded figure to calculate the numbers on the Nutrition Facts panel.

According to the June complaint, Chobani's own label states that 3/4 cup of this yogurt weighs 190 grams. Working backward, the plaintiff alleges that 170 grams of the product is only about 0.671 cups — which rounds to the nearest standard increment of 1/2 cup, not 3/4 cup. Using a 1/2-cup serving, the complaint says the correct "equivalent metric quantity" would be roughly 168.9 grams, and the product would contain about 17.78 grams of protein per serving — a figure FDA rules permit to be rounded to 18 grams on the label.

Instead, both complaints allege, Chobani declares a 3/4-cup (190-gram) serving, which the June complaint says inflates the serving size and therefore every per-serving figure — including protein — by about 12.5 percent. The plaintiff alleges that this is what allows the 32-ounce tub to carry the "20G Protein" name and the "20g per serving" claim at all. Chobani has not yet answered these allegations, and the calculation is the plaintiff's, not a court finding.

Single-Serving Cups Versus the 32-Ounce Tub

The June complaint draws a sharp line between Chobani's two formats. It alleges that the single-serving cups are sized at 6.7 ounces — more than the industry's typical 5.3-ounce Greek-yogurt cup — so that they hold enough yogurt to genuinely provide 20 grams of protein. That format, the complaint says, is not the focus of the lawsuit.

The 32-ounce multi-serving tub is different, according to both complaints, because Chobani allegedly did not add more yogurt to reach 20 grams per serving. Instead, the plaintiffs allege, it expanded the declared serving on paper. The August complaint makes the same point about the single-serving format, alleging Chobani sized those cups at 6.7 ounces — above the 5.2-ounce cups it says competing brands use — because it could not reach 20 grams in a standard-sized serving. The complaint contends that for multi-serving containers the FDA gives manufacturers "relatively little discretion" over serving size, so the alleged inflation is, in the plaintiff's words, prohibited rather than a matter of judgment.

The "20 Grams" Marketing

Beyond the package itself, the complaint points to Chobani's broader marketing of the "20g of protein" message — including website copy describing the yogurt as "packed with 20g of complete protein," social-media posts about its "straining process," and a post introducing the 32-ounce tub as "equal to about 5 of our single-serve cups." The plaintiff alleges none of this discloses that, on his reading of the FDA rules, the multi-serving tub provides about 18 grams per serving rather than 20. The complaint frames 20 grams as a recognized consumer "threshold" for protein, which it says makes the difference material to buyers. Chobani disputes claims of this kind generally, and these characterizations remain unproven allegations.

Who Is Covered and What the Lawsuits Seek

Both complaints propose a nationwide class of U.S. purchasers of the 32-ounce "20G Protein" tubs. The June complaint adds a New York subclass and brings claims under New York General Business Law sections 349 (deceptive acts and practices) and 350 (false advertising), along with a claim for unjust enrichment. The August complaint adds both a New York subclass and a Florida subclass, and pleads the two New York counts, two Florida counts under the Florida Deceptive and Unfair Trade Practices Act and Fla. Stat. section 817.41, and a nationwide unjust enrichment count.

The plaintiffs seek class certification, an injunction against the challenged labeling, and monetary relief — including actual and statutory damages, restitution, interest, and attorneys' fees. The June complaint also requests treble damages; the August complaint asks the court to require Chobani either to change the labeling or to reformulate the product so a properly calculated serving contains 20 grams. As with any newly filed complaint, those are requests, not awards. No money has been ordered and none is available now.

What Happens Next?

Both cases are at an early stage. No class has been certified in either, meaning no court has decided whether they can proceed on behalf of all affected purchasers. Chobani will have an opportunity to answer each complaint and may move to dismiss or narrow the claims — food-labeling cases of this kind are frequently contested on whether a reasonable consumer would actually be misled and on preemption by federal labeling law. If a case survives, the parties would exchange evidence in discovery before any class-certification decision.

A second suit on the same theory does not make the allegations more likely to succeed; it is common for one food-labeling complaint to be followed by others against the same defendant. Because the August plaintiffs filed a statement of relatedness, the court may consider whether to handle the two together, but no ruling on that has been reported. Many proposed consumer class actions are dismissed, narrowed, or settled before any payout, and there is no guarantee either case results in a settlement or recovery.

This case fits a broader wave of food and beverage lawsuits challenging label and nutrition claims, alongside actions like the Gatorade "Hydrates Better Than Water" lawsuit, the Royo keto bread calorie-labeling lawsuit, and the protein powder heavy-metals investigation.

Do I Need to Do Anything Right Now?

No. There is no claim form, no deadline, and no settlement fund in either case. Consumers do not need to save receipts or contact the court. If either case ever advances to a settlement or judgment, class members would be notified about how to participate.

Frequently Asked Questions

Is there a Chobani settlement or claim form?
No. These are newly filed complaints, not settlements. There is no claim form and no guarantee that consumers will ever receive money from either case.

What do the lawsuits allege?
That Chobani's 32-ounce "20G Protein" tubs do not really provide 20 grams of protein per serving. Both complaints say FDA serving-size rules call for a smaller serving than the 3/4 cup Chobani declares — 1/2 cup in the June case, 2/3 cup in the August case — which would yield about 17.8 grams, rounded to 18 grams on the label.

Which products are named?
The 32-ounce multi-serving "20G Protein" Greek yogurt tubs; the June complaint identifies the plain and vanilla varieties specifically. The single-serving 6.7-ounce cups are not challenged in either case.

Do the single-serving cups really have 20 grams?
According to the June complaint, yes — the smaller cups are sized to hold enough yogurt to actually deliver 20 grams of protein, which is why they are not part of the lawsuit. The August complaint makes a related point, alleging those cups were enlarged to 6.7 ounces precisely because the standard cup size would not reach 20 grams.

Are there two Chobani protein lawsuits?
Yes. Knox v. Chobani, LLC, No. 1:26-cv-05093-VEC, was filed June 16, 2026, and Lombardo v. Chobani, LLC, No. 1:26-cv-07408, was filed August 31, 2026 — both in the U.S. District Court for the Southern District of New York. The August case adds Florida consumer-protection claims and a Florida subclass. Its plaintiffs filed a statement of relatedness flagging the earlier case; whether the two are handled together is up to the court.
