Ozempic, Wegovy inspire wave of GLP-1 supplements—but are they safe or effective?

As interest in diabetes and weight-loss medications such as Ozempic, Wegovy, and Zepbound surged in recent years, supplement manufacturers responded by launching a number of GLP-1-branded products including pills, powders, drops, and patches. However, experts quoted in a July 29 PBS article warned that these supplements do not come close to matching the effectiveness of real GLP-1 agonists such as semaglutide (sold under the brand names Ozempic and Wegovy) and tirzepatide (sold as Mounjaro and Zepbound). In addition, the supplements are not strictly regulated, meaning consumers cannot be sure of what they are actually buying

 Do GLP-1 Supplements Work? Doctors Set the Record Straight on ‘Nature’s Ozempic’

Brands like Kourtney Kardashian’s Lemme are claiming to provide the same benefits as GLP-1 medications like Ozempic, Wegovy, and Mounjaro. But the truth is, these supplements have little to nothing in common with the drugs.

 Supplements claiming to work like Ozempic and Wegovy are now being sold – here’s what the evidence actually says about these products

Although there are many supplements that claim to mimic GLP-1, none are anywhere near as effective as GLP-1 receptor agonist drugs. It’s also important to note that any evidence showing some of these supplements may temporarily increase GLP-1 is limited. So not only is there limited evidence these supplements can aid in weight management, many have potential side-effects – some of which can be quite severe.

Kourtney Kardashian just launched an Ozempic style supplement - but experts are warning against taking it

Kardashian's supplement contains a lemon fruit extract called Eriomin, which the brand claims is "shown to increase GLP-1 levels, support insulin function and support healthy blood glucose levels in the normal range." However, while the website refers to clinical studies, we can't find any links to the studies to be able to analyse them. In short, our experts were clear: stick with medically advised treatments for the best outcomes and safety.

GLP-1 patches for weight loss have made the scene—but a leading MD warns you they aren't the same as the more familiar prescriptions.

Do GLP-1 Supplements Work?

While these supplements may have “GLP-1” in the name, there is no GLP-1 in any of these products, said Dr. Donna Ryan, an obesity medicine specialist at Pennington Biomedical Research Center. For example, the three main ingredients in the Lemme GLP-1 Daily capsules are Superesa saffron extract, Morosil red orange fruit extract, and Eriomin lemon fruit extract. While the website emphasizes that these are “clinically investigated” ingredients shown to increase GLP-1 and help with appetite regulation, none of the studies cited included participants with diabetes. Here’s a closer look at some of the common ingredients found in GLP-1 supplements.

Do ‘Natural GLP-1 Supplements’ Actually Work As Well As Ozempic?

These can all impact the body, yes, but it’s a stretch to suggest that these would have the same effect as GLP-1 receptor agonist medications, says Mir Ali, MD, a bariatric surgeon and medical director of MemorialCare Surgical Weight Loss Center at Orange Coast Medical Center.

GLP-1 Patches: What They Are, What They Can’t Do, and What You Should Know

We do not recommend GLP-1 patches. Despite the marketing, these patches do not contain any real GLP-1 medications like semaglutide or tirzepatide. Instead, they are made from herbal blends and vitamins with no clinical evidence supporting weight loss or metabolic benefits. They are a misleading alternative that cannot match the proven effectiveness of FDA-approved GLP-1 treatments.

GLP-1 Patches: What They Claim vs. What Science Says

Media reports and expert commentary, however, point out that the science doesn’t support these claims. Current GLP-1 patches do not contain the actual GLP-1 peptide, lack regulatory approval, and remain unproven in clinical research. Despite slick marketing, they are not substitutes for medically approved treatments.

In the gray world of GLP-1 supplements online, health experts urge caution

Supplement manufacturers have capitalized on the explosive popularity of diabetes control and weight loss drugs such as Ozempic, Wegovy and Zepbound by flooding the market with their own pills, powders, drops and patches bearing “GLP-1” branding.

Nature’s Ozempic: A Look Into the Supplement Berberine

There is a fair amount of research supporting its positive effect on health in the medical literature. The herb has been used for centuries in traditional medicine, so most of the important studies have been published in Chinese medical journals.

The Weight Loss Hacks That Claim to Work Like Ozempic

There’s a long list of products that companies and influencers claim can deliver quick and dramatic weight loss, just like Ozempic. There are gummies filled with fruit extract, neon yellow berberine tablets, green teas, even jars of oatmeal and rice steeped in lime water. The latest addition to that list: a weight loss pill released this week by Lemme, Kourtney Kardashian’s supplement company. Weight loss hacks have been around for decades. But they have taken on new life in the Ozempic era, chasing the success of blockbuster medications and promising “natural” or “side-effect free” alternatives.

GLP-1 patches are the latest breakthrough in weight control — but not all live up to the science. As endocrinology specialists, we compared the top formulas, delivery systems, and real-world results to find which ones truly support healthy, sustainable weight loss in women.

Why GLP-1 Patches Don’t Deliver—Yet

Products sold as “GLP-1” patches do not contain GLP-1 or GLP-1 analogues (similar molecules). Instead, they contain ingredients that they claim help your body produce GLP-1 naturally, such as caffeine, berberine, and other herbal extracts. While there is evidence that some ingredients may promote GLP-1 production in the body8,9, there is little evidence that these can reduce body fat long-term.

Why the Supplement Berberine Is Not ‘Nature’s Ozempic’

Social-media platforms like TikTok are full of people conducting their own one-person trials of what they’re calling “nature’s Ozempic.” The oral supplement berberine, a compound found in turmeric and several other plants, can dupe the appetite-suppressing and weight-loss effects of the popular injection, they say—but without a prescription, high copay, or shot. The only problem is that there’s really no such thing as “nature’s Ozempic,” because Ozempic is far from natural.
