Buyers of Grüns Superfood Greens Gummies and the Grüns Cubs children’s version may be covered by a proposed class action alleging the supplements were sold as “comprehensive nutrition” while containing no protein, fat, calcium or omega-3 fatty acids. A federal judge dismissed most of the case in May 2026, holding the phrase is hype no reasonable shopper would rely on; no class has been certified and there is nothing to file.
Allegations Only · No Settlement Yet
This article describes a class action complaint and a ruling on a motion to dismiss. The statements attributed to the complaint are unproven allegations. Grüns Nutrition, Inc. has contested them, no court has found the company liable, no class has been certified, and there is nothing to claim. A dismissal decides whether claims were adequately pleaded, not whether the product works. This page is informational and is not legal advice.
What Happened
There is nothing for buyers to claim, and the case is smaller than it was. On May 19, 2026, Judge Lewis J. Liman of the Southern District of New York granted Grüns Nutrition's motion to dismiss the amended complaint. The two New York consumer claims were dismissed without prejudice, with permission to replead one narrow theory. Everything else — the California claims, common law fraud and unjust enrichment — was dismissed with prejudice.The plaintiffs filed an amended complaint on June 8, 2026, and Grüns moved to dismiss again on June 22. That motion was fully briefed by mid-July 2026, and no ruling on it appears on the public docket. No class has been certified, and no settlement has been reported.
What the Lawsuit Claims
The complaint, filed June 13, 2025, is about one word. Grüns sells its gummies under a front-of-package line reading “Comprehensive Nutrition,” and the children's pouch reads “Comprehensive Nutrition for Kids” alongside “All-In-One.” The suit alleges that message runs through everything the company publishes — the packaging, the website, marketing emails from its customer service address, retailer listings, and a social media campaign the complaint describes as so prolific that more than 200 separate ads went live across Meta platforms on a single day in May 2025.The alleged problem is what the gummies do not contain. According to the complaint they have no protein and no fat, including no omega-3 fatty acids, no calcium, about 6 grams of fiber against a 28-gram daily value, and 4.5 milligrams of iron. The plaintiffs alleged that a product missing entire categories of nutrient cannot honestly be sold as covering a person's nutritional needs, and that the claim let Grüns charge a premium — the complaint cites list prices of $79.99 and up for the adult gummies, $87.99 for the sugar-free version, and up to $50.24 for a four-week children's pouch.
Two audiences drew particular attention. Advertising aimed at people taking GLP-1 medications such as Ozempic promoted the gummies as covering nutrients lost while eating less. Advertising aimed at parents presented them as a way around the vegetable fight, with one ad comparing the monthly cost of the gummies against a month of produce. The claims were brought under New York General Business Law §§ 349 and 350, three California statutes, common law fraud, and unjust enrichment.

Why the Judge Called “Comprehensive Nutrition” Hype
The ruling turns on puffery, the doctrine that some advertising is too exaggerated for anyone to rely on. The court took the phrase at its word first. Nutrition means nourishment sufficient to sustain life, so a product genuinely providing comprehensive nutrition would remove any need to eat anything else. Applied to a 0.7-ounce packet of gummy bears labeled a dietary supplement, the court called that reading plainly hyperbolic — and made a point that decides a lot of supplement cases: “The very notion of a ‘supplement’ is that it adds to what is being consumed and not that it replaces it.”The plaintiffs did not argue for the literal reading. They offered narrower ones — that the phrase promises all essential nutrients, or replaces other supplements, or stands in for fruits and vegetables. That retreat created the second problem. If “comprehensive nutrition” does not mean what the dictionary says, the court held, it is ambiguous, and an ambiguous front label sends a reasonable shopper to the back of the package. There the panel lists more than 60 ingredients, 100% of the daily value for certain vitamins, and much smaller numbers elsewhere: 5% for carbohydrates, 21% for dietary fiber, 25% for iron, iodine and zinc. The court found it evident from that panel that the gummies contain no protein, fat, calcium or omega-3s at all.
That reasoning is why two cases the plaintiffs leaned on did not carry. In suits over a “complete multivitamin” and a “complete” multivitamin missing 13 required vitamins, the word “complete” modified “vitamin” — a bounded, checkable set, so the front label made a false promise the fine print could not cure. Here the modifier attaches to “nutrition,” which takes in macronutrients as well, and the court held it is one thing to believe a pill might hold every vitamin and quite another to believe a single pack of gummies holds every nutrient a healthy diet requires.
The One Theory That Nearly Worked
The court did find a set of ads a reasonable consumer might plausibly be misled by, and they were the ones aimed at GLP-1 users. Marketing telling people on Ozempic that the gummies are “specifically designed to fill in the gaps” reads differently from a general boast, because the definite article implies that the medication creates identifiable, uniform gaps and that this product fills those particular gaps. Nothing in the surrounding material dispelled that impression: listing 21 vitamins and minerals clarifies that the gummies do not contain everything, but not that they fail to cover what a GLP-1 user specifically loses.The claim failed anyway, on the plaintiffs' own pleading. Identifying a potentially misleading ad is only half the job; a complaint also has to allege that the ad is false. The amended complaint said the formulation “is not tailored to the specific needs of GLP-1 users,” which the court called conclusory — it never identified what gaps the medication creates, or what the gummies are missing that would fill them. As the opinion put it, so far as the complaint showed, the gummies may well contain the vitamins and minerals a GLP-1 user's diet needs.
That is why this piece was dismissed without prejudice while everything else was not, and it is the only thing the plaintiffs were given leave to fix.
What Was Dismissed for Good
The California claims went out with prejudice for a reason specific to who was suing. California's consumer statutes require actual reliance, and the California plaintiff is not alleged to be a GLP-1 user or to have seen the GLP-1 advertising — so the one surviving theory was not available to her, and the rest failed for the same reasons as the New York claims.Common law fraud failed on intent. Proving a company knew its claim was false takes more than showing the claim was false, and the plaintiffs' evidence of knowledge was that Grüns ran two ads the same day giving different figures for how many children fall short on fiber — 95% in one, 78% in the other. The court found the two figures are not necessarily inconsistent, that neither was alleged to be false, and that a gap between them says nothing about whether the company knew its nutrition claim was untrue.
The unjust enrichment count was dismissed as duplicative. It rested on the same facts as the statutory claims, so there was no scenario in which it could succeed where those failed — which is also why it could not be preserved as an alternative theory.
What Happens Next
The renewed motion to dismiss has been fully briefed since July 2026 and is awaiting decision. If the amended complaint cures the GLP-1 defect the court identified, a narrow New York case proceeds on that advertising alone; if it does not, there is very little left. Fact discovery in the case closed in May 2026 and expert discovery in July, so the litigation is further along procedurally than the pleadings suggest.For a shopper, the practical position has not changed since the case was filed. There is no fund, no claim form and no settlement, and a website inviting Grüns claims is not connected to this litigation. Anyone weighing the products can do what the court did and read the supplement facts panel, which states what is in them and what is not.
Frequently Asked Questions
Can I file a claim in the Grüns gummies lawsuit?
No. No class has been certified, there is no settlement, no fund and no claim form. Most of the case was dismissed in May 2026, and what remains is at the pleading stage with a second motion to dismiss awaiting decision. Any site inviting you to file a Grüns claim is not connected to this case.
What did the judge decide about the phrase comprehensive nutrition?
Judge Lewis J. Liman held it is not something a reasonable shopper would take literally. Read literally it would mean a person could eat the gummies and nothing else, which the court called plainly hyperbolic for a 0.7-ounce packet sold as a dietary supplement, noting that the very idea of a supplement is that it adds to a diet rather than replacing it. Read any other way the phrase is ambiguous, and the court found the back label resolves the ambiguity.
Do the gummies contain protein, fat or calcium?
No. Reading the product's own back label, the court found it evident that the gummies contain no protein, no fat, no calcium and no omega-3 fatty acids. The label lists 100% of the daily value of certain vitamins alongside much smaller figures elsewhere, including 5% for carbohydrates, 21% for dietary fiber and 25% for iron, iodine and zinc.
What part of the case survived?
Only the New York claims, and only as to advertising aimed at people taking GLP-1 medications such as Ozempic. The court found those ads more specific than the general marketing, because they suggest the medication creates identifiable nutritional gaps that the gummies fill. It dismissed them anyway, without prejudice, because the complaint never said what those gaps are or why the gummies fail to fill them.
Is the Grüns case over?
Not entirely. The plaintiffs filed an amended complaint in June 2026 and Grüns moved to dismiss again later that month. That motion was fully briefed by July 2026 and no ruling appears on the public docket. The California claims and the fraud and unjust enrichment counts were dismissed with prejudice and cannot come back.
