What Are UMF and MGO Decoding Manuka Honey Grading Systems
Manuka honey is celebrated for its natural health benefits, but what do the terms UMF and MGO really mean? Understanding these grading systems can help you make an informed decision about the honey you buy and use.
What is MGO?
MGO, or Methylglyoxal, is the key compound responsible for the antibacterial potency of Manuka honey. Measured in milligrams per kilogram (mg/kg), MGO provides a direct indication of how potent the honey is. For example:
- MGO 83+ is considered mild and suitable for everyday use.
- MGO 261+ and above are medium-strength grades ideal for health and immune support.
- MGO 512+ and higher are strong grades used for targeted health benefits.
MGO levels are easy to measure and scientifically validated, making them a reliable indicator of the honey’s potency.

What is UMF?
UMF, or Unique Manuka Factor, is an internationally recognised grading system that certifies the quality and authenticity of Manuka honey. Managed by the UMF Honey Association in New Zealand, this rating considers four main components:
- Methylglyoxal (MGO): A compound that gives Manuka honey its antibacterial properties.
- Leptosperin: A naturally occurring chemical unique to Manuka nectar.
- DHA (Dihydroxyacetone): A precursor to MGO found in the nectar.
- HMF (Hydroxymethylfurfural): Measures the freshness of the honey and whether it’s been over-heated.
UMF grades typically range from 5+ to 35+, with higher numbers indicating stronger antibacterial properties. It’s the gold standard for ensuring that your honey is genuine and meets strict quality requirements.
The UMF grade can only be used by certified brands who are members the UMFHA (UMF’s incorporated society based in New Zealand) as the grading system and associated logo are trademarked by UMF™.
Each UMFHA member has a unique license number which must be displayed on product label. This license number can be looked up on the UMFHA web site. There is no equivalent for MGO rating system.
Our manuka honeys also have a QR code on the lid stickers which takes you to our website where you can look up your honey’s batch number to see the official grading test results and UMF certificate.

FAQ
Can I use MGO ratings alone to determine honey quality?
MGO ratings provide valuable information about antibacterial strength, but they don’t account for other factors that contribute to Manuka honey’s overall quality. For a more comprehensive assessment, choose honey with a UMF certification, which includes MGO and other essential markers.
Why do UMF and MGO values differ across brands?
The differences often come down to testing methods and honey sources. UMF certification ensures consistency by adhering to strict testing standards, whereas MGO-only grades may vary depending on the producer. Always look for the UMF mark to ensure reliable and accurate grading.
How do I know if my honey is UMF-certified?
Check the label for the official UMF™ logo and grading. You can also verify the product by checking the brand’s membership with the UMF Honey Association. At Manuka South, all our Manuka honey is UMF™-certified for your peace of mind.
Is Manuka honey safe for everyone?
Manuka honey is generally safe for most people but as with all honey should not be given to infants under one year of age due to the risk of botulism. If you have specific health concerns, consult with your healthcare provider before using it.
Can I use Manuka honey topically?
Yes! Manuka honey with higher UMF grades (15+ or above) is excellent for topical application on minor wounds, burns, and skin irritations due to its antibacterial and healing properties. Ensure the honey is medical-grade if using it for wound care.
How should I store Manuka honey?
Store your Manuka honey in a cool, dry place away from direct sunlight. There’s no need to refrigerate it. Proper storage preserves its natural properties and ensures it remains effective over time.
