The Lemme GLP-1 lawsuit is a proposed class action filed in March 2025 against Lemme Inc., the supplement company co-founded by Kourtney Kardashian Barker, alleging that its Lemme GLP-1 Daily capsules are falsely advertised as a natural weight-loss aid comparable to prescription GLP-1 medications like Ozempic and Wegovy. The case, Robins v. Lemme Inc., argues the science behind the product does not support its marketing. Lemme has called the suit “frivolous.”1Bloomberg Law.

What the Lawsuit Claims
The core allegation is that Lemme’s advertising leads consumers to believe its capsules work like prescription GLP-1 drugs when the two are not comparable. Prescription drugs such as Ozempic and Wegovy use modified amino acid sequences to raise GLP-1 blood concentrations roughly 300,000 to 600,000 percent above resting levels, with effects lasting for days. Naturally occurring GLP-1 has a half-life of one to two minutes. The complaint argues that Lemme’s claim of boosting the body’s own GLP-1 by 17 percent, through a lemon extract ingredient, is not enough to produce any meaningful effect on weight or appetite.2ClassAction.org. Robins v. Lemme Inc., Complaint
Lemme marketed the $90 capsules as a way to “boost GLP-1 hormone levels” naturally and promoted benefits including “healthy weight loss,” “burning visceral fat,” and “appetite control,” referring to GLP-1 as the “un-hunger” hormone. Co-founder Simon Huck described the supplement as a way to raise GLP-1 “naturally in your body without having to take a synthetic drug,” positioning it for people who had stopped taking prescription GLP-1 medications because of side effects or cost.2ClassAction.org.

The Studies Cited Against Lemme
The complaint argues that the research Lemme relies on actually undermines its claims. It points to two published clinical trials on Eriomin, the product’s primary ingredient. A 2019 double-blind randomized controlled study by Ribeiro et al. found Eriomin supplementation at three dosages had “no effect on body weight, BMI, lean mass, fat mass, fat percentage, and hip waist ratio” over 12 weeks.4National Library of Medicine. Effectiveness of Eriomin in Managing Hyperglycemia and Reversal of Prediabetes Condition A 2022 crossover-randomized trial by Cesar et al., involving 30 subjects, similarly reported “no effect on blood pressure (systolic and diastolic), body weight, BMI, lean mass, fat mass, and ratio hip/waist.”5National Library of Medicine.

The complaint also states that no clinical study has tested the specific three-ingredient combination in Lemme GLP-1 Daily, which contains Eriomin lemon fruit extract, Supresa saffron extract, and Morosil red orange fruit extract. Sample sizes in the individual ingredient studies were too small, the complaint argues, to support the company’s marketing claims.2ClassAction.org. Robins v. Lemme Inc., Complaint

What Outside Experts Say
Medical experts unconnected to the litigation have echoed some of the complaint’s scientific concerns. Dr. Supriya Rao told PopSugar, “I truly believe that this is not going to do much for anybody.”10PopSugar.
