How we rank, and what counts as “legit”

Scoring for every provider on this page runs against our published six-factor rubric[1]: value, effectiveness, user experience, trust & safety, accessibility and support.

Each of Wegovy, Zepbound, Ozempic and Mounjaro holds its own separate FDA approval under its own NDA number[4][5]. Published Phase 3 efficacy for semaglutide at 2.4 mg (~14.9% mean weight loss across 68 weeks) comes from STEP 1[6]; those for tirzepatide (~20.9% at the 15 mg dose over 72 weeks) come from SURMOUNT-1[7]. In 2025 the SURMOUNT-5 head-to-head set the two against each other[8].

How much of an anti-obesity medication is covered varies widely between state Medicaid programs and between commercial plans[9][10]. Under IRS Publication 502, compounded GLP-1s and brand-name ones alike are generally FSA/HSA eligible where a prescription exists[11].

Arrived here looking for “natural Ozempic,” a “GLP-1 supplement,” or the best over-the-counter “natural GLP-1”? Not one OTC supplement is a GLP-1 receptor agonist. The products sold as “natural Ozempic” or “GLP-1 support” — apple cider vinegar, berberine, capsaicin, chromium, soluble fiber — work on unrelated pathways, and pooled they come to roughly 1–2 kg of weight loss. Prescription semaglutide (−14.9%, STEP 1) and tirzepatide (−20.9%, SURMOUNT-1) are roughly 10x stronger. If you want one anyway, the supplement board ranks what is actually sold, with the same scoring we apply everywhere else. It will not turn any of them into a GLP-1.

Frequently Asked Questions

For meaningful weight loss, most over-the-counter supplements have weak evidence or none, and not one of them is a GLP-1 receptor agonist. Fiber and protein, among a few ingredients, can support appetite control modestly as part of a diet. Treat a bold 'natural Ozempic' claim skeptically, because no supplement matches prescription semaglutide or tirzepatide.
No. Not one OTC supplement is a GLP-1 medication. What gets marketed as 'natural GLP-1' or 'GLP-1 support' — fiber blends, berberine and the like — may nudge appetite or blood sugar a little, and it does not replicate what a prescription GLP-1 drug does. The real thing requires a prescription.
Regulation of supplements is far lighter than for medications, leaving quality and safety to vary widely, with real risks present: stimulants, interactions with drugs, ingredients that go undisclosed. Stay with reputable brands. Where you take other medications, check with a clinician first. And treat anything promising dramatic results with suspicion.
Six weighted dimensions produce the score. Value (25%) and Effectiveness (25%) carry the most, then User Experience (15%) and Trust & Safety (15%), then Accessibility (10%) and Support (10%). Behind them sits our research into pricing data, clinical evidence, user reviews and publicly available information. Those weights then combine into one overall score out of 10.
The six-dimension methodology computes each score on its own, and no commercial relationship ever moves a provider's underlying number. Every provider's full score sits on its card for you to check. Some providers do hold affiliate agreements with us, which means a commission reaches us if you click through and buy. On the lists carrying the highest commercial intent — the weight-loss injection and shot lists, the semaglutide and tirzepatide lists, the compounded and cheapest molecule lists, and the fitness-app list — affiliate partners take the top positions. Every other list runs in score order, or in price order on the cheapest lists. That placement is disclosed here, on our methodology page, and on our affiliate-disclosure page.
