MGO vs UMF: Understanding the Difference
When it comes to choosing high-quality Manuka Honey, two grading systems often appear on labels—MGO (Methylglyoxal) and UMF (Unique Manuka Factor).
Both indicate the honey’s potency, but they differ in their methods and scope.
-
MGO refers to the concentration of Methylglyoxal, a compound responsible for the antibacterial properties of Manuka Honey. The higher the MGO number, the stronger the antibacterial strength.
-
UMF is a more comprehensive grading system that also takes into account other key markers, such as Leptosperin, DHA (Dihydroxyacetone), and HMF (Hydroxymethylfurfural).

Which is Better: MGO or UMF?
While UMF provides a more complete evaluation of Manuka Honey, MGO is simpler and more straightforward to test. Therefore, you can’t necessarily say one system is better or more reliable than the other—they both serve as good indicators of quality.
