If you’ve previously searched for Manuka honey, you may have come across a number of grading systems, and one of these grading systems is MGO Manuka Honey – but what is it and what does it test for?
What is MGO Manuka Honey?
The MGO in Manuka honey refers to Methylglyoxal, which is a chemical compound that is found in Manuka honey. MGO provides the antibacterial effect that is so often spoken about. The MGO grading system tests for the Methylglyoxal contained within the honey. However, Methylglyoxal can be produced synthetically and added to the honey during manufacturing process, so the test does not offer a true sign of purity and quality when it comes to evaluating genuine Manuka.
UMF™ (Unique Manuka Factor) on the other hand, tests for all three naturally occurring chemical markers of the honey; Methylglyoxal (MGO as mentioned, the antibacterial element), Dihydroxyacetone (also known as DHA, the age of the honey), and Leptosperin (the indicator of genuine Manuka). Only UMF™ standard tests for Leptosperin, which can only be found in Manuka honey and cannot be fabricated.
To offer a comparison with the MGO Manuka honey you may see, here are the levels of Methylglyoxal found within each UMF™ rating:
- UMF™ 5+ has a minimum MGO 83
- UMF™ 10+ has a minimum MGO 263
- UMF™ 15+ has a minimum MGO 514
- UMF™ 18+ has a minimum MGO 698
- UMF™ 20+ has a minimum MGO 829
Here at Comvita, we test for MGO in the Manuka honey, as well as DHA and Leptosperin, then rate the potency of honey based on the UMF™ grading system. We can therefore ensure that the Methylglyoxal in our Manuka products is naturally occurring, providing you with a genuine taste of one of nature’s special gifts.
Government Testing for Manuka Authenticity
In order to offer further reassurance to suppliers and customers around the world that they are indeed investing in Manuka honey that is genuine, all products marked ‘Manuka’ that are intended for export from New Zealand must now be subjected to independent DNA tests.
Unveiled by the New Zealand Ministry for Primary Industries earlier this year, the new Manuka honey science definition protects the reputation of one of the rarest types of honey in the world, as it continues to grow in popularity, connecting people with nature and good health.

No matter the period of its cultivation; from the moment it is created in our hives, to when you place it in your shopping basket, our Manuka honey can be traced. Every step we take during its creation involves constant monitoring, checking and testing in order to ensure that the honey we produce is indeed natural and pass all purity tests that it needs to go through.
