What are the alternatives to GLP-1s, and do they work?
Supplements, "natural GLP-1" claims, and older prescription weight-loss drugs compared.
"Nature's Ozempic" Claims: A Fact CheckBerberine, yerba mate, psyllium, apple cider vinegar, Akkermansia and oat water have all been called "nature's Ozempic." We checked each claim against the trial data, the retractions and the regulatory record. Here is what holds up and what does not."Research Peptides" and the Gray Market: What Buyers Need to KnowVials labeled semaglutide, tirzepatide or retatrutide sold "for research purposes only" are the highest-risk option in the weight-loss market. The FDA says they are illegally sold unapproved drugs, and a 2026 analysis of 652 patients found gray-market retatrutide produced less weight loss and more cardiovascular symptoms than the real drug.Berberine vs Ozempic: What the Evidence Actually SaysBerberine has been called "nature's Ozempic" since 2023. It is a real plant compound with real effects on blood sugar and cholesterol, but pooled trial data show it produces somewhere between zero and two pounds of weight loss, compared with roughly 33 pounds for semaglutide in its main trial. Here is the side-by-side.Contrave vs Wegovy: Which Weight Loss Drug Fits Which Person?Contrave is an oral pill aimed at cravings and food reward. Wegovy is a weekly injection that produces roughly three times more weight loss. Contrave can cost as little as $20 a month with a copay card. Here is the full comparison, including the boxed warning most people do not know about.Every FDA-Approved Weight Loss Drug, Compared (2026)Nine drugs and one device are currently FDA-approved or cleared for weight management in the United States, plus two withdrawn ones worth knowing about. This is the full list with trial results, costs, risks and the 2026 professional guidance on choosing between them.GLP-1 Supplements: Do Any of Them Actually Work?GLP-1 boosters, GLP-1 patches, GLP-1 probiotics and GLP-1 drops are now a multi-billion-dollar category. We went through the ingredient evidence, the lawsuits and the FDA and FTC record to answer one question: is there anything in here that works?Metformin for Weight Loss vs GLP-1s: How Big Is the Gap?Metformin costs a few dollars a month, has a 60-year safety record, and produced about 2 kg of weight loss in the Diabetes Prevention Program that held for a decade. Semaglutide produced 15 kg in 68 weeks. Here is what metformin is genuinely good at, and where the comparison stops making sense.Phentermine vs GLP-1s: Cost, Results and Who Each One SuitsPhentermine costs about $14 to $41 a month and has been on the market since 1959. Wegovy and Zepbound cost $299 to $449 and produce three to five times more weight loss. Here is the real comparison, including the label limits most articles skip.Qsymia vs Zepbound: The Best Pill Against the Best InjectionQsymia produced about 10.9% weight loss in its pivotal trial and now costs around $60 a month as a generic. Zepbound produced 20.2% and costs $299 to $449. This is the closest thing to a fair fight between an old oral drug and the strongest GLP-1 class medication.
