Manukora Review: MGO Is a Real Number - and Manuka Honey Is Still 80% Sugar

This is the genuinely useful technical content, because mānuka is one of the most counterfeited food products in the world and the grading system is how you avoid buying diluted honey. MGO stands for methylglyoxal, measured in milligrams per kilogram. It is the compound responsible for mānuka's distinctive antibacterial activity, formed from dihydroxyacetone (DHA) present in mānuka flower nectar, which converts to MGO as the honey matures. MGO 850+ means at least 850 mg of methylglyoxal per kilogram. It is a direct chemical measurement. UMF — Unique Manuka Factor — is a New Zealand grading and licensing system that tests MGO, DHA and leptosperin together. Leptosperin is the authenticity marker: it is found in mānuka nectar and is very difficult to fake, so its presence indicates the honey genuinely comes from Leptospermum scoparium rather than being ordinary honey spiked with something. Roughly how they correspond: UMF 10+ ≈ MGO 263+; UMF 15+ ≈ MGO 514+; UMF 20+ ≈ MGO 829+; UMF 24+ ≈ MGO 1122+. Manukora's MGO 850+ sits at approximately UMF 20+. What to check when buying any mānuka: A specific MGO or UMF number, not a vague "active" or "manuka blend" claim. Third-party testing, ideally with the certificate available. New Zealand origin with traceability. New Zealand operates a government definition and export testing regime for mānuka honey specifically because of the counterfeiting problem. "Monofloral" rather than "multifloral" if you want the higher-activity product. Does higher MGO justify the price? In terms of measured antibacterial activity in a laboratory, yes — more MGO is more MGO. Whether that translates into more benefit when you eat it is a separate question, and one the next section deals with honestly. For most eating purposes, a mid-grade mānuka delivers the flavour and most of what people are after at a fraction of the cost of MGO 1000+. On the glyphosate-free certification. A reasonable additional assurance and a genuine differentiator in a market where residues have been found in honey generally. It is a purity claim, not an efficacy one.

Here is the honest position, separated into what is well supported and what is not. Wound care is the strong case, and it is genuinely strong. Medical-grade mānuka honey — sterilised by gamma irradiation and produced as a regulated wound dressing — is used in clinical practice, and there are FDA-cleared mānuka honey wound dressings on the market. The mechanism is well characterised: high sugar concentration draws moisture out of bacteria, low pH, hydrogen peroxide activity, and methylglyoxal, which mānuka has and other honeys do not. Crucially: that is medical-grade, sterilised honey applied to a wound. Do not put food-grade honey from a jar on a wound. Unsterilised honey can contain bacterial spores, including Clostridium botulinum, and applying it to broken skin is not the same intervention. A sore throat: the reasonable middle case. Honey generally — not specifically mānuka — has reasonable evidence for soothing cough and sore throat, and is recommended by several health bodies as an option for cough in children over one year. The effect is largely demulcent — coating and soothing — and is not unique to mānuka. Ordinary honey does this at a fraction of the price. Digestive health, immunity, "whole-body wellness": this is where the claims outrun the evidence. There is preliminary work on mānuka and Helicobacter pylori and on gut bacteria in laboratory settings, but human trial evidence that eating mānuka honey improves immunity or digestive health is thin to absent. Laboratory antibacterial activity does not transfer straightforwardly to the gut, where the honey is diluted, digested and reaches a very different environment. And the fact the category rarely mentions: honey is roughly 80% sugar. A tablespoon is around 60 calories and 17 grams of sugar. That is not a criticism of honey as a food — it is a reason to be clear-eyed. Taking a daily spoon of mānuka "for wellness" is adding sugar to your diet. If you have diabetes or are managing blood glucose, honey raises blood sugar much like other sugars do and should be counted. Never give honey to an infant under 12 months. Infant botulism is caused by C. botulinum spores that honey can contain, and an infant's gut allows them to germinate. This applies to raw, pasteurised and mānuka honey alike, and to anything containing honey.

On price. MGO 850+ from $64 and MGO 1000+ from $96 are typical premium mānuka prices — this is an expensive food, and the price reflects genuine scarcity. Mānuka flowers for only a few weeks a year, in a limited geography, and yields vary with weather. That is a real supply constraint, not a manufactured one. Whether it is worth it depends entirely on what you want it for: For flavour and as a premium honey: a matter of taste, and mānuka is genuinely distinctive — richer, more caramel and mineral than clover honey. For a sore throat: ordinary honey does essentially the same job, and the evidence for the soothing effect is not mānuka-specific. For the antibacterial properties: the laboratory activity is real and grade-dependent, and whether it survives digestion to do anything systemically is unproven. As a health investment: we would not frame it that way. It is a good honey with an interesting compound in it. The quality signals Manukora publishes are the right ones: third-party testing for purity and potency, 100% traceability to source, monofloral designation, glyphosate residue-free certification, and amber glass packaging — worth noting because light degrades honey's peroxide activity over time, so amber glass is a functional choice rather than an aesthetic one. What to ask for: the test certificate for the batch you receive, showing MGO and, ideally, leptosperin. A brand this focused on testing should provide it on request. Storage. Cool, dark, sealed, with a clean dry spoon. Crystallisation is normal and is not spoilage — warm the jar gently in warm water if you want it liquid again, but avoid high heat, which degrades MGO and the peroxide activity. Do not microwave it. On the reviews. 4.88 across 17,035 reviews is a large, specific figure, and third-party-collected reviews are more meaningful than testimonials. The 25,000+ overall figure is company-stated and we could not independently verify it.

What does Manukora cost? MGO 850+ from $64 and MGO 1000+ from $96, with free shipping over $75. What does MGO mean? Methylglyoxal in milligrams per kilogram — the compound responsible for mānuka's distinctive antibacterial activity. It is a direct chemical measurement. How does MGO compare to UMF? Roughly: UMF 10+ ≈ MGO 263+, UMF 15+ ≈ MGO 514+, UMF 20+ ≈ MGO 829+, UMF 24+ ≈ MGO 1122+. UMF also tests DHA and leptosperin, the authenticity marker. Is higher MGO worth the extra money? More MGO is more measured laboratory activity. Whether that translates to more benefit when eaten is unproven. For eating, mid-grade delivers the flavour and most of the practical benefit far more cheaply. Does manuka honey boost immunity? Human trial evidence for eating it improving immunity or digestive health is thin to absent. The strong evidence is topical wound care with medical-grade sterilised product. Can I put it on a cut? Not food-grade honey. Medical-grade manuka wound dressings are sterilised regulated products; jar honey can contain bacterial spores. Does it help a sore throat? Honey generally has reasonable evidence for soothing cough and sore throat. That effect is not specific to manuka — ordinary honey does it far more cheaply. Is it safe for babies? No honey of any kind under 12 months, because of infant botulism risk. Can I have it if I have diabetes? Honey is roughly 80% sugar and raises blood glucose much like other sugars. Count it, and discuss with your clinician. Why has it crystallised? That is normal. Warm the jar gently in warm water; avoid high heat, which degrades the compounds.
