What’s the difference between MGO (MG) and UMF in Manuka honey?

Both MGO (Methylglyoxal) and UMF (Unique Manuka Factor) are measures of antibacterial strength in Manuka honey.

MGO, identified by the University of Dresden in Germany, is the direct compound responsible for Manuka’s antimicrobial activity and is recognised by the New Zealand government.

Each batch of Rojel Manuka Honey is tested in NZ-accredited labs and clearly labelled with its MGO content.
