There are four better-known grading systems for Manuka Honey and two well-known measurements.
These grading systems are Unique Manuka Factor (UMF), BioActive, KFactor, Molan Gold Standard (MGS).
The measurements are Methylglyoxal (MGO) and Non-Peroxide Activity (NPA).
Manuka Honey has been around for many years. However, it was only 38 years ago that Doctor Peter Molan from the University of Waikato in New Zealand discovered the power of Manuka Honey. Since then organisations have been established to conduct their own extensive research on Manuka Honey due to its incredibly unique properties.
In 1998 the UMFHA was founded to do just that and protect not only the Manuka Honey industry but its consumers as well. The UMF grading system, and measuring of MG levels, is the oldest, most well established and widely recognised grading system of Manuka Honey in the world.
