The Kardashian family has been named in supplement-related lawsuits and regulatory complaints for more than a decade, most recently in a proposed class action against Kourtney Kardashian Barker’s brand Lemme over its GLP-1 Daily capsules. That case, filed in early 2025, echoes a 2012 class action against Kim, Khloe, and Kourtney Kardashian over the QuickTrim weight-loss line, and it sits alongside a series of endorsement-disclosure controversies involving Fit Tea, paid Instagram promotions, and a separate SEC action against Kim Kardashian over cryptocurrency.
The Lemme GLP-1 Daily Lawsuit
Lemme launched GLP-1 Daily in September 2024, marketing the capsule as a plant-based way to raise the body’s production of GLP-1, a hormone the brand called the “un-hunger hormone.”1NutraIngredients. Lemme Lawsuits Challenge GLP-1 Supplement Claims2PR Newswire. Lemme Innovates With Natural GLP-1 Supplement Lemme’s marketing positioned it as a “natural alternative” to prescription GLP-1 drugs like Ozempic and Wegovy, promising to “reduce hunger & cravings, promote fat reduction and support healthy weight management.” Product labels carry an asterisk noting that GLP-1 Daily is not a weight-loss supplement and does not contain synthetic GLP-1 or act as an agonist.
In February 2025, California resident Christina Robins filed a proposed class action against Lemme Inc. in California Superior Court, followed by a parallel complaint in the U.S. District Court for the Southern District of New York on March 9, 2025 (Case No. 1:25-cv-01938).3Bloomberg Law. Kardashian Vitamin Brand Lemme Sued Over GLP-1 Supplement Claims The New York filing was later dismissed for lack of jurisdiction, and the case continued in California.4Supply Side SJ. Class Action Targets Kardashian GLP-1 Supplement Robins says she bought GLP-1 Daily from Lemme’s website, took it as directed for more than three months, and gained five pounds. She contends she would not have purchased the supplement had she known the marketing claims were unsubstantiated.1NutraIngredients. Lemme Lawsuits Challenge GLP-1 Supplement Claims
The complaint brings claims under California’s unfair competition and false advertising statutes and New York General Business Law sections 349 and 350, and seeks to represent a nationwide class and a California subclass of consumers who bought GLP-1 Daily from Lemme’s website.5ClassAction.org.

Why the Science Is in Dispute
The heart of Robins’s case is a biology argument. Naturally occurring GLP-1 has a half-life of one to two minutes because the body’s enzymes break it down almost immediately. Prescription drugs like semaglutide are engineered to resist that breakdown and last roughly seven days in the bloodstream.5ClassAction.org. Robins v. Lemme Inc., Complaint The plaintiff argues that a modest increase in a hormone that vanishes within minutes cannot meaningfully affect weight, especially given that eating a normal meal raises GLP-1 levels by 400% to 900% on its own.1NutraIngredients. Lemme Lawsuits Challenge GLP-1 Supplement Claims A single 1 mg dose of Ozempic, the complaint notes, produces blood concentrations 300,000% to 600,000% higher than resting GLP-1 levels.
The complaint also targets the studies Lemme relies on. Each ingredient was tested separately, not as the three-extract combination sold as GLP-1 Daily, so the finished product has never been clinically tested as a whole.4Supply Side SJ. Class Action Targets Kardashian GLP-1 Supplement The main study on Eriomin, published in Phytotherapy Research in June 2019, was a double-blind, randomized, placebo-controlled trial of 103 prediabetic participants over 12 weeks. It found a 15% increase in GLP-1 levels and improvements in fasting glucose and insulin resistance, with 24% of participants reversing their prediabetic condition.7National Library of Medicine. Effectiveness of Eriomin in Managing Hyperglycemia and Reversal of Prediabetes Condition The complaint alleges that the same study reported no changes in body weight, BMI, lean mass, fat mass, fat percentage, or waist-hip ratio, and that results in prediabetic subjects do not translate to weight loss in the general population.5ClassAction.org.

QuickTrim: The 2012 Class Action
The Lemme case is not the first supplement class action to name Kardashians. In March 2012, four customers filed a $5 million proposed class action in the Southern District of New York against Kim, Khloe, and Kourtney Kardashian, along with QuickTrim LLC, its CEO Christopher Tisi, distributor Windmill Health Products, and retailers including GNC, Walmart, and CVS.8NutraIngredients. GNC, Walmart and the Kardashians Targeted in QuickTrim Lawsuit
Plaintiffs alleged the sisters falsely claimed in television commercials, on their websites, and on social media that they used QuickTrim to slim down. The complaint described the products as “caffeine pills mixed with a variety of herbal ingredients that have never been clinically proven as effective treatments for weight loss.”8NutraIngredients. GNC, Walmart and the Kardashians Targeted in QuickTrim Lawsuit The “Burn & Cleanse” system contained 400 milligrams of caffeine per dose, equivalent to about four cups of coffee, along with stimulant laxatives such as senna and cascara that health experts warned could cause dehydration, nutrient loss, and intestinal dependency.9U.S. News & World Report. The Dangers of Kardashian-Endorsed QuickTrim The complaint cited an FDA determination that caffeine is not recognized as safe or effective for weight control, though industry observers noted that finding applied to over-the-counter drug standards rather than dietary supplements.
An amended complaint filed in July 2012 added allegations that the sisters promoted QuickTrim through deceptive social media posts. Kim Kardashian had said on television that she and her sisters “formulated” the product, and Khloe Kardashian tweeted about a QuickTrim cleanse; plaintiffs pointed to both as evidence that the endorsements went beyond passive packaging appearances.10Steptoe.

Endorsement Disclosure Problems
Around the same period, the family drew regulatory attention over how paid endorsements were disclosed on social media. The National Advertising Division reviewed endorsements by Kourtney Kardashian, Khloe Kardashian, and Kylie Jenner for the dietary supplement Fit Tea and found the posts failed to disclose that the endorsers were paid. Fit Tea agreed to revise its posts and comply with FTC endorsement guidelines going forward.11Davis & Gilbert LLP. NAD Action Requiring Kardashians
In August 2016, the consumer advocacy group Truth in Advertising filed a formal complaint with the FTC alleging that the Kardashian-Jenner family had published paid social media posts for 27 companies without proper disclosure. Family lawyers said they would update the posts and ensure future compliance; some were deleted or edited to add “#ad,” though 75 posts reportedly remained unchanged at the time the FTC complaint was filed. The FTC did not publicly announce any formal enforcement action based on that complaint.12BuzzFeed News. FTC Complaint Filed Over Kardashian Social Media
Kim Kardashian did face a separate federal enforcement action in October 2022, when the Securities and Exchange Commission charged her with violating securities laws by failing to disclose a $250,000 payment she received for promoting the cryptocurrency EthereumMax on Instagram. She agreed to pay $1.26 million in penalties and disgorgement and accepted a three-year bar on promoting crypto securities.13U.S. Securities and Exchange Commission. SEC Charges Kim Kardashian for Unlawfully Touting Crypto Security That case involved cryptocurrency rather than supplements, but it fit the broader pattern of disclosure disputes.
What This Means for Consumers of GLP-1 Supplements
The Lemme case is part of a wider push against GLP-1 supplement marketing. Dietary supplements do not require FDA approval before going to market, and manufacturers are not required to provide clinical evidence supporting their claims before selling the products.14diaTribe. Do GLP-1 Supplements Work
In December 2025, the FTC issued a final order against telemedicine company NextMed over unsubstantiated weight-loss claims tied to GLP-1 programs, fake testimonials, and deceptive billing, ordering $150,000 in consumer refunds.15Federal Trade Commission. FTC Approves Final Order Against Telehealth Provider NextMed Earlier that year, in July 2025, Senator Marsha Blackburn and Tennessee Attorney General Jonathan Skrmetti urged the FTC to investigate deceptive advertising of products marketed as alternatives to FDA-approved weight-loss drugs, citing research on manipulative marketing and more than 900 adverse events tied to compounded GLP-1 products.16U.S. Senate. Blackburn, Skrmetti Call for FTC Investigation Into Questionable Online Marketing of Alternatives to FDA-Approved Weight Loss Medications
If you bought GLP-1 Daily from Lemme’s website, you may be within the proposed class definition the Robins complaint seeks to certify. The case is still pending in California, so no claims process or settlement fund exists yet. Any recovery would depend on the court certifying a class, the parties reaching a settlement, or a judgment on the merits.
