New York, NY — A federal judge dismissed a proposed class-action lawsuit accusing Grüns Nutrition Inc. of misleading consumers by marketing its gummy supplements as a “comprehensive” nutritional solution, ruling the plaintiffs failed to plausibly show the advertising deceived reasonable buyers.
In a May 19 opinion and order, U.S. District Judge Lewis J. Liman granted Grüns Nutrition’s motion to dismiss claims filed by plaintiffs Patricia Cavallaro-Kearins and Jenifer Mestaz-Heiser in the Southern District of New York.
The lawsuit targeted Grüns Nutrition’s “Superfood Greens Gummies” for adults and children, products marketed online and through retailers as providing “comprehensive nutrition,” “complete” daily nutrition, and “all-in-one” dietary support.
Consumers Claimed Gummies Failed to Deliver Promised Nutrition
According to the complaint, the plaintiffs alleged they purchased the products after relying on Grüns’ marketing claims about the gummies’ nutritional benefits.
Cavallaro-Kearins, a New York resident, said she bought sugar-free versions of the gummies from the company’s website in December 2024. Mestaz-Heiser, a California resident, purchased Grüns Adults gummies in March 2025.
The plaintiffs argued they would not have bought the supplements had they known the representations were allegedly misleading.
Court filings said Grüns marketed the products as:
- “Comprehensive nutrition”
- “Complete” nutrition support
- “All-in-one” dietary supplementation
- Products capable of supporting daily nutritional needs
The lawsuit also highlighted the products’ premium pricing, with some adult gummy varieties retailing for nearly $88.
Key Points
• A federal judge dismissed a class-action lawsuit against Grüns Nutrition over supplement marketing claims
• Plaintiffs argued the company falsely advertised gummies as “comprehensive” nutritional solutions
• The court ruled the complaint failed to plausibly show consumers were misled
The complaint accused Grüns of overstating the products’ nutritional value through packaging and online marketing that allegedly implied the gummies could replace essential nutrients or provide complete daily nutrition.
Judge Grants Motion to Dismiss
Judge Liman ruled in favor of Grüns Nutrition under Federal Rules of Civil Procedure 9(b) and 12(b)(6), standards commonly used to test whether fraud-related claims are sufficiently detailed and legally plausible.
The opinion stated the motion to dismiss was granted after the court reviewed the allegations contained in the plaintiffs’ amended complaint.
While the filing excerpt does not include the judge’s full legal reasoning, dismissals in consumer advertising lawsuits often hinge on whether a “reasonable consumer” would likely interpret marketing statements as literal factual guarantees or generalized promotional language.
The ruling marks another example of increased litigation targeting health, wellness, and supplement companies over claims tied to nutrition, weight loss, and functional health benefits.
Companies selling supplements have faced growing scrutiny in recent years over labels using terms such as “complete,” “comprehensive,” “natural,” or “all-in-one,” particularly when plaintiffs argue the claims imply broader medical or nutritional outcomes.
Current Status
The federal court granted Grüns Nutrition’s motion to dismiss the amended complaint on May 19. The opinion did not indicate whether the plaintiffs plan to amend their claims again or pursue an appeal.
