UMF (Unique Manuka Factor) is New Zealand’s independent grading system for genuine Manuka honey, measuring four signature compounds: MGO, Leptosperin, DHA and HMF.
Higher grades mean higher potency: UMF 5+ (MGO 83+) suits everyday wellness, UMF 10+ (MGO 263+) daily immune support, UMF 15+ (MGO 514+) advanced support, and UMF 20+ to 25+ (MGO 829 to 1197+) maximum potency.
ApiHealth is a licensed UMF producer (licence #1052) in Auckland, New Zealand. Every batch is independently lab-tested and verifiable by the batch number on your jar.
Every grade is the same pure, certified New Zealand Manuka honey. The difference is potency. Select a grade to compare strength, uses, and price.

The most popular starting strength for health-focused use. Moderate antibacterial activity for everyday immune and digestive support, and our best-selling grade.
Not sure where to start? UMF 10+ is our most popular grade for daily immune support.
Every jar is UMF certified under licence #1052, independently tested, and shipped fresh from our Auckland facility.





Each UMF grade guarantees a minimum level of MGO (methylglyoxal), the naturally occurring compound behind Manuka honey's potency.

Not all Manuka honey ratings mean the same thing. UMF is the only system that cross-checks potency, authenticity, and freshness through independent labs.
| System | What It Measures | Independently Verified? | What It Tells You |
|---|---|---|---|
| UMF | Four markers: MGO, Leptosperin, DHA and HMF | Yes, licensed by the UMF Honey Association, tested by accredited third-party labs | Potency, authenticity, shelf-life stability and freshness |
| MGO | Methylglyoxal only | Varies, often tested in-house with no licensing body | Potency only; no authenticity or freshness check |
| NPA | Non-peroxide antibacterial activity (phenol equivalent) | Lab-tested, but a single-compound measure | Antibacterial strength only |
| K-Factor | Pollen count (monofloral vs multifloral) | A single brand’s own trademark | Whether it contains Manuka nectar, not how potent it is |
Anyone can print a number on a label. We back every grade with a UMF licence, independent lab results, and batch-level traceability you can check yourself.

ApiHealth is a licensed member of the UMF Honey Association, the only body authorised to certify UMF grades. Look for licence #1052 on every jar.
Every batch is tested by an accredited third-party laboratory against the four-compound UMF standard before release. We never grade our own honey.
Harvested, extracted, tested, and packed in New Zealand under an MPI-registered Risk Management Programme. Never blended with imported honey.
Each jar carries a batch number linked to its UMF release certificate, so you can see the exact lab results for the honey in your hands.
Methylglyoxal, the key antibacterial compound that defines each grade.
Found only in genuine Manuka nectar and impossible to add artificially.
Converts to MGO over time, confirming potency will hold across shelf life.
A low reading proves the honey was never overheated or stored poorly.
UMF stands for Unique Manuka Factor, the independent grading system run by the UMF Honey Association in New Zealand. Accredited labs test each batch for four naturally occurring compounds: Leptosperin (a marker unique to Manuka nectar that cannot be added artificially), DHA (which converts to MGO over time, protecting long-term potency), MGO (the key antibacterial compound), and HMF (an indicator of freshness and careful handling).
Many Manuka honeys are sold on an MGO number alone, a single compound with no authenticity or freshness check behind it. UMF is the only system that cross-checks all four markers through accredited third-party labs, making it significantly harder to fake. When you buy a UMF graded jar, you are buying honey that passed a multi-factor test, and with ApiHealth, one you can trace back to the lab report.
From everyday UMF 5+ to rare-reserve UMF 25+, every jar is batch-traceable, lab-verified, and shipped direct from New Zealand.
