UMF and MGO Ratings

UMF™ is shorthand for the most comprehensive, independently certified and internationally recognised quality assurance system for New Zealand mānuka honey. It’s designed to validate mānuka honey potency, authenticity, purity, shelf life and freshness for honey producers, brands, customers and consumers around the world.

The UMF™ guarantee means that you can be sure that Mānuka honey bearing the UMF™ mark contains the special activity.

MGO FOR POTENCY
Methylglyoxal, to give it its full name, is the source of golden mānuka honey’s special antibacterial properties and an important potency measure. The higher the MGO, the stronger the concentration of MGO.
