Moringa and berberine patches are stick-on patches sold as a “natural” way to curb appetite and lose weight, often next to talk of GLP-1 and Ozempic. Two names that come up a lot are Purisaki and Luxarise. This guide is desk research: I haven’t used the patches myself. I looked at what the published research says, what the FDA and NIH say, and what buyers report on complaint sites, so you can decide before you order.
The short answer: I found no human study showing that berberine gets into the body through the skin from a patch, and no trial of berberine or moringa patches for weight loss. Even swallowed berberine is absorbed poorly, and its effect on weight is not proven. Buyer complaints about these patches centre on no results, unwanted repeat orders and difficult refunds.
What are moringa and berberine patches?
They’re adhesive patches you stick on your skin, usually one a day. Sellers say plant ingredients such as berberine and moringa pass through the skin into the bloodstream, skipping digestion, and help with appetite, blood sugar or weight. Many are marketed as a “natural GLP-1” alternative to weight-loss injections.
A 2026 editorial in The Annals of Pharmacotherapy looked at 24 of these “natural GLP-1” patch products and one gel. They listed an average of seven plant or nutrient ingredients each, and berberine was among the most common. None of the products posted a certificate of analysis (an independent test of what’s actually in them), many lacked the standard FDA disclaimer, and the authors described much of the advertising as deceptive (White et al., 2026).
I couldn’t find the amount of berberine or moringa per patch on either the Purisaki or the Luxarise website, so there’s no way to compare the dose with the amounts used in studies.
Do berberine patches work?
There’s no good evidence that they do.
- No human study of berberine through the skin. On October 25, 2026 I searched PubMed for studies of berberine applied as a patch, gel or through the skin in people. I found lab and animal work on special berberine gels and microneedle patches for skin conditions such as psoriasis and wounds, but no clinical trial of berberine patches and no human study measuring berberine in the blood after it was applied to the skin. C. Michael White, head of pharmacy practice at the University of Connecticut, made the same point to TODAY: “there’s no research showing what happens when berberine is applied in patch form” (TODAY, 2025).
- Swallowed berberine is absorbed poorly. Because of its chemistry, less than 1% of swallowed berberine reaches the bloodstream (2024 review). Skin is designed to keep things out, so a patch is not an obvious improvement.
- Even oral berberine isn’t proven for weight loss. The NIH’s National Center for Complementary and Integrative Health (NCCIH) says some studies suggest berberine might help with weight loss, “but the evidence is not conclusive.” In a 2022 review, the effects on weight were seen mainly in people taking more than 1 gram a day by mouth, and the individual studies were inconsistent (NCCIH). A 2020 meta-analysis of oral berberine found small reductions in weight and BMI (Asbaghi et al., 2020).
- Moringa’s human research is about eating it. A 2026 review of 22 clinical trials of moringa found the most consistent results for immune function, blood sugar control and antioxidant status, not weight (2026 review). I found no human study of moringa applied through the skin for weight loss.
If a patch seems to reduce your appetite, that can’t be attributed to the patch: no study has tested it, and paying attention to what you eat when you start any new product can change your habits on its own.
What the FDA says
“There are no FDA-approved GLP-1 patches,” the FDA told TODAY, and the agency added that there are no FDA-approved drug products containing berberine (TODAY, 2025). Under US law, dietary supplements are products you swallow; the authors of the 2026 editorial argue that patch “supplements” therefore don’t qualify as legal dietary supplements at all (White et al., 2026).
Berberine patch vs capsule
| Berberine patch | Berberine capsule | |
|---|---|---|
| How it’s meant to get in | Through the skin | Swallowed, absorbed in the gut |
| Human studies | None found | Many trials, mostly in people with type 2 diabetes or high cholesterol |
| Evidence for weight loss | None found | Limited: small effects, inconsistent studies |
| Dose per day | Not disclosed by the sellers I checked | Shown on the label; effects on weight were seen mainly above 1,000 mg a day |
| Known side effects | Skin irritation reported by some buyers; other effects unknown | Mainly stomach upset: nausea, bloating, constipation or diarrhea |
| US status | Not a legal dietary supplement form, according to the 2026 editorial | Sold as a dietary supplement |
If you’re curious about berberine, the capsule form is the one with research behind it. My berberine supplement review covers what the trials found, the doses used and who should avoid it.
Purisaki berberine patches: what I found
- Who sells them: Purisaki’s terms say the brand is operated by Bewell EU, a company in Vilnius, Lithuania, and that most goods ship from China, so import fees may apply outside the EU (Purisaki terms).
- Ordering: when I checked on October 25, 2026, the Purisaki site said new orders were paused “due to exceptionally high demand”. Its only health wording on that page was “Feel Full Faster”.
- Subscriptions: the terms describe a subscription billed monthly (or on the schedule chosen at sign-up) that you can cancel through the contact form or by email; cancellation generally takes effect the following month.
- Returns: the return policy gives 60 days from delivery. Items must come back in their original condition and undamaged packaging with a return (RMA) form and tracking number, and shipping costs aren’t refunded (Purisaki return policy).
Purisaki reviews and complaints
On October 25, 2026, Purisaki’s Trustpilot page showed a TrustScore of 3.7 from about 6,400 reviews: 67% four or five stars and 25% one star. That page covers the whole Purisaki store, the company invites all its customers to review, and some of the positive reviews I read are about ordering rather than results.
In the one-star reviews I read, the recurring complaints were:
- No weight loss or appetite change after several weeks or months of use (16 of the 20 one-star reviews I read).
- Refunds refused, delayed or smaller than expected, sometimes because a return form was missing.
- Repeat orders arriving after what buyers thought was a one-time purchase, and subscriptions that were hard to cancel.
- Support that didn’t reply, and a few paid orders that never arrived.
- Skin irritation or sores where the patch was worn (a small number of reviews).
Trustpilot’s own summary of recent reviews also mentions unwanted automatic refills and repeated add-on offers at checkout. These are individual customer reports, not verified findings.
Luxarise moringa and berberine patches
I could find much less about Luxarise. The seller’s site, luxarise.be, blocked my visits, so I couldn’t check its ingredient list, claims or refund policy. Note that luxarise.com is a different, unrelated shop selling wall art, so check the address carefully before you order anything.
The Trustpilot page for luxarise.be lists a Brussels address and had only five reviews on October 25, 2026, with a TrustScore of 2.7. Four were one star: an order paid in January that hadn’t arrived by April, a charge of €92.68 against an order of €74.14 that the reviewer says was explained only afterwards as insurance and admin fees, and two buyers who saw no weight loss and asked for a refund. The one four-star reviewer said they felt less hungry between meals but hadn’t lost weight. The company hadn’t replied to the negative reviews. Five reviews are too few to draw firm conclusions.
Common complaints about weight-loss patches
Across the sellers I looked at, the same problems come up again and again: no results, repeat shipments that buyers didn’t knowingly sign up for, and refund rules (unused items only, return forms, short windows, shipping you pay for) that are hard to meet. The Better Business Bureau has warned about subscription traps in weight-loss products more generally (BBB tip).
If you do order:
- Read the checkout page for any box that sets up a subscription or “auto-refill”, and untick it if you don’t want one.
- Screenshot the order page, the price and the refund policy on the day you buy.
- Keep the packaging, and put a calendar reminder a week before the refund window ends.
- Pay by credit card if you can, so you can dispute a charge you didn’t agree to.
Side effects and who should avoid berberine patches
- Skin reactions: some buyers report itching, inflammation or sores where they wore the patch. Purisaki’s terms say not to use the patches if you’re allergic to any of the ingredients listed on the package.
- Unknown dose: because the amount that gets through the skin hasn’t been measured, nobody knows the real dose, or whether it’s enough to interact with medicines. White, quoted by TODAY, raised a further concern: substances that skip the gut and liver also skip the body’s usual first round of processing.
- Medicines: swallowed berberine can interact with some drugs, including cyclosporine, and NCCIH advises talking with your health care provider first if you take any medicine (NCCIH). Berberine can also lower blood sugar, which matters if you take diabetes medication. My berberine side effects guide covers the full list of side effects, medicine interactions and what over-50s should check.
- Pregnancy and breastfeeding: NCCIH says berberine is likely unsafe for infants and may be unsafe during pregnancy or breastfeeding.
Talk to your doctor or pharmacist before using any berberine product, patch or capsule, especially if you take regular medicine, have diabetes, or are pregnant or breastfeeding.
If you want something with more evidence
The changes with the strongest evidence for weight are still the unglamorous ones: eating fewer calories, more protein and fibre, and staying active. If you’re weighing up a supplement, these pages may help:

Berberine patches FAQ
Do berberine patches work?
There’s no evidence that they do. I found no human study showing berberine is absorbed through the skin from a patch, and no trial of berberine or moringa patches for weight loss. Even swallowed berberine, which has been studied, hasn’t been proven to help with weight loss.
Do berberine patches have side effects?
Some buyers report skin itching, inflammation or sores where they wore the patch. Because nobody has measured how much berberine a patch delivers, other effects and drug interactions are unknown. Swallowed berberine mainly causes stomach upset and can interact with some medicines, so talk to your doctor first if you take any.
Is a berberine patch better than a capsule?
No. The capsule is the form with research behind it, and you can see the dose on the label. Patches haven’t been tested in people, and the sellers I checked don’t say how much berberine each patch contains.
Are moringa and berberine patches FDA approved?
No. The FDA has said there are no FDA-approved GLP-1 patches and no FDA-approved drug products containing berberine.
Are Purisaki patches legit?
Purisaki is a real company (Bewell EU, Lithuania) with a written return policy, but I found no evidence that its patches work, and its one-star reviews describe no results, unwanted repeat orders and refund problems. If you order, check the checkout for subscription options and keep track of the 60-day return window.
