Manuka Honey MGO vs UMF Calculator

Below is a table of UMF vs MGO grading numbers to help you better compare and calculate the antibacterial activity levels stated on New Zealand Manuka Honey jars.

UMF and MGO are the two most widely used grading systems of Manuka Honey internationally.

Are UMF and MGO the same?

No. While UMF grading does include MGO as one of the potency markers of Manuka Honey it is a more comprehensive Manuka testing system as it covers additional authenticity markers as well.

UMF measures:

  • Methylglyoxal (MGO) - antibacterial levels in Manuka honey
  • Leptosperin - indicates that the honey comes from the Manuka plant
  • Dihydroxyacetone (DHA) - in the nectar of the Manuka flower
  • Non-peroxide activity (NPA) - the additional anti-bacterial activity in Manuka honey

MGO only measures:

  • Methylglyoxal (MGO)
