UMF and MGO Ratings

MGO Rating

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 : This rating provides insight into the honey's potency and effectiveness. Essentially, the higher the MGO rating, the greater the concentration of methylglyoxal, which typically means a more potent product with enhanced antibacterial and therapeutic properties.
