Kourtney Kardashian Barker's supplement brand, Lemme, has faced significant criticism following the launch of several products, most notably an "Ozempic-style" weight-loss supplement. This comes amidst ongoing speculation that her sisters, Kim, Khloe, and Kylie, have used the actual diabetes drug Ozempic for weight loss. Lemme, which Kourtney launched in September 2022, is now accused of capitalizing on the popular drug's hype, despite offering products that lack the same scientifically proven efficacy.

Lemme's controversial new supplement, named GLP-1 Daily, directly references the GLP-1 hormone targeted by Ozempic. The brand markets it as a solution to "reduce body weight, visceral fat, and hip and waist circumference." While Ozempic is a weekly injectable containing a synthetic version of the GLP-1 hormone that slows digestion and dulls hunger, Lemme's pill does not contain any of Ozempic's key ingredients. Instead, it claims to naturally increase GLP-1 levels using lemon and saffron extracts, positioning itself as a "GLP-1 solution without the side effects." However, this has drawn sharp criticism from both fans and medical professionals. Priced at a steep £69 for a one-time purchase, the product has been slammed for potentially exploiting insecurities and engaging in false marketing. Plastic surgeon Naveen Cavale called it "incredibly misleading" and a "cash grab," particularly harmful to young women struggling with body image, suggesting it could exacerbate mental health issues.

Beyond the GLP-1 Daily, Lemme has faced backlash for other products. The brand's "Lemme Smooth" capsules, marketed to reduce cellulite in just 28 days using French Cantaloupe Melon extract, have also been dismissed by experts. Cavale labeled these pills an "ineffective solution to a perfectly normal condition," emphasizing that cellulite is natural and common, and such products lack significant scientific backing. He advises a holistic approach including diet and exercise, and fostering positive body image, rather than relying on unproven and costly remedies that can lead to frustration and worsened body image issues.

Another product that drew ire was Lemme Purr, vagina gummies marketed to boost vaginal health and alter its taste with pineapple, Vitamin C, and probiotics. Gynecologist Dr. Jen Gunter vehemently criticized this product, stating, "Anyone who suggests that your vagina isn't fresh or needs an improved taste is a misogynist and awful person. And yes, that includes you Kourtney Kardashian and your Lemme grift."

A consistent point of contention across all these products is the lack of evaluation by the Food and Drug Administration (FDA). Lemme's small print explicitly states, "This product is not intended to diagnose, treat, cure or prevent any disease." This disclaimer highlights a crucial difference from FDA-approved drugs, which undergo rigorous testing for efficacy and safety. Critics argue that despite Kourtney's long-standing public image as the most health-conscious Kardashian sister—an interest she claims was sparked after the birth of her first son, Mason—her brand's offerings fall short of scientific scrutiny and appear to exploit societal pressures for quick fixes. Medical professionals consistently advise consulting a doctor for effective health and weight loss solutions, warning against the false hope and potential psychological harm from unproven supplements.
