[Home](https://glucosebench.com/) 2. [Reviews](https://glucosebench.com/reviews) 3. Gluco Extend review: the longest refund, no label Gluco Extend gives you 180 days to ask for your money back and no supplement facts panel to read. By **[GlucoseBench editorial team](https://glucosebench.com/about)** Updated October 16, 2026 ![Gluco Extend bottle, as shown on the seller's website](https://glucosebench.com/img/guia-gluco-extend-768.webp?v=497880a03c) Short answer Gluco Extend has the longest refund we've found, 180 days, but its page publishes no label, so no dose can be checked. It's a capsule sold for healthy blood sugar levels. The page names six ingredients (berberine, gymnema, turmeric, cocoa, a "bean extract" and a "leaf extract") with no amounts. You pay once, and the retailer lists it for sale worldwide. If you take diabetes medication, show your doctor the ingredient list before you order: berberine and gymnema are both sold for blood sugar. Quick note: this page has affiliate links.

[How we review and how we earn](https://glucosebench.com/affiliate-disclosure) [Check price on the seller's site](https://go.glucosebench.com/c/gluco-extend--gluco-extend)[Or compare the packages and price per day](https://glucosebench.com/gluco-extend#pacotes) ## At a glance - ### Gluco Extend **Best for:** buyers outside the US, or anyone who wants the most time to decide, who can live without knowing the doses and has shown the ingredient list to a doctor #### Pros - 180-day refund, three times the 60 days almost every other product here offers - Listed for sale worldwide by the retailer - One-time payment, "no auto ship subscriptions" - Names its main ingredients, even without amounts #### Cons - No supplement facts panel, so no amount for any ingredient - The page can't agree with itself: "11+" ingredients, six ingredient cards and a "blend of 4 plants and minerals" - "Bean extract" and "leaf extract" never say which bean or which leaf - The serving size is never stated - A "Dr. Recommended" badge on a physician assistant, and university logos borrowed from another product **Verdict** The refund makes it easy to back out of; the missing label makes it hard to judge. If you buy, do it knowing you're paying for the 180 days, not for a dose you can check. [See Gluco Extend on the seller's site](https://go.glucosebench.com/c/gluco-extend--gluco-extend) ## What the page says is inside There's no label on the page, so this comes from the ingredient cards. None gives an amount. Ingredient Amount per capsule Worth knowing Berberine Not disclosed Sold for blood sugar; ask your doctor first if you take medication Gymnema Not disclosed Sold for blood sugar Turmeric Not disclosed Also in the Glyco Pulse blend Cocoa Not disclosed Also in the Glyco Pulse blend "Bean extract" Not disclosed The plant isn't named "Leaf extract" Not disclosed The plant isn't named Source: the official Gluco Extend page, read on September 27, 2026. The page describes a "proprietary blend of 11+ plants and nutrients" in one place and a "blend of 4 plants and minerals" in another. The bottle photo shows 30 capsules; the page never gives the serving, so our cost per day assumes one capsule a day, which is how the packages add up to 30 days a bottle. ## What you'll pay per day Package Price Per day Shipping Extras 2 bottles (60 days) $158.00 $2.63 Extra, amount not shown [Pick this size on the order page](https://go.glucosebench.com/c/gluco-extend--gluco-extend) 3 bottles (90 days) $207.00 $2.30 Free in the US 3 bonuses [Pick this size on the order page](https://go.glucosebench.com/c/gluco-extend--gluco-extend) 6 bottles (180 days)Lowest price per day $294.00 $1.63 Free in the US 3 bonuses [Pick this size on the order page](https://go.glucosebench.com/c/gluco-extend--gluco-extend) Checked on September 27, 2026 (Gluco Extend order section, US prices). The order page can change these prices at any time, and the total at checkout is the one that counts. US delivery takes 7 to 10 business days. Outside the US "shipping fees will apply", and the page doesn't say how much. It also shows crossed-out "was" prices; we left them out, since the product isn't sold at those prices anywhere on the page. ## The 180-day refund, in plain terms ### The window 180 days. Write to the seller in that time and the page promises "every single cent" back. ### What to send back The FAQ says to return what you haven't used. It doesn't say whether empty bottles count or who pays to ship the return. ### Who to ask The vendor, through the product support link at the bottom of the page. No email address appears in the text. ## Gluco Extend's pitch, against what you can verify The page says What you can actually check Ingredients that support healthy blood sugar, backed by research The page lists 14 references, and none of their titles names an ingredient in the formula. With no amounts, there's nothing to compare with a study anyway. "Dr. Recommended" The face under the badge is labeled "Physician Assistant". Whether that person exists and agreed to it can't be checked from the page. Harvard, Stanford, Yale and Columbia logos The image files sit in a folder named after a different product. "Based on 127,000 reviews" Not one of them can be read on the page. A "January 2026" scientific discovery from the National Library of Medicine No study title, author or link is given. A guarantee "if you are not impressed by the transformation in your brain health" Text copied from another product's page. The refund itself is still written as 180 days. ## Who should buy it, and who shouldn't ### Worth a look if You live outside the US, UK, Canada, Ireland, Australia and New Zealand, or you want half a year to change your mind, and you've shown the ingredient list to your doctor. ### Skip it if You want to know how much berberine you're taking (no product we've reviewed prints it), you're pregnant or nursing, or you take medication and haven't asked your doctor. ## Side effects and medication cautions The NIH's complementary health center (NCCIH) says berberine "may interact with some medicines", that anyone taking medicines should talk with a health care provider before using it, and that it "should not be used during pregnancy or while breastfeeding". Nausea, diarrhea, bloating and constipation are its common side effects. Without a label, you also can't check what else is in the capsule, such as fillers or allergens. That's one more reason to ask the seller for the supplement facts panel before a doctor's visit, not after. ## Frequently asked questions **Is Gluco Extend legit?** The 180-day refund and the one-time payment check out. What doesn't: no label, borrowed university logos and text copied from other products, so "legit" and "well documented" aren't the same thing here. **What are the Gluco Extend ingredients?** The page names berberine, gymnema, turmeric, cocoa, a bean extract and a leaf extract. It gives no amounts and publishes no supplement facts panel. **Does Gluco Extend have side effects?** Berberine commonly causes stomach upset, according to NCCIH, and it may interact with some medicines, so ask your doctor first if you take any. **How long is the Gluco Extend refund?** 180 days, the longest clearly stated refund of any blood sugar product we have reviewed. **Does Gluco Extend ship internationally?** The retailer lists it for sale worldwide. The page quotes US delivery times and says shipping fees apply outside the US, without naming countries or the amount. ## Ordering Gluco Extend **Refund:** 180 days, according to the page.
