MGO and UMF are ways to rate the Methylglyoxal content of the honey. This is the main antibacterial, naturally occuring compound in Mānuka honey. It can vary from batch to batch and from season to season.
MGO = Methylglyoxal
This a key property when it comes to health benefits of the honey. The higher the MGO, the higher the potency. Our MGO rating is thouroughly tested by labs in both New Zealand and the United States.
UMF = Unique Mānuka Factor
Another rating you might see on Mānuka honey is UMF, a testing process developed by the UMF honey Association in New Zealand. It takes into account MGO as well as other compounds unique to Mānuka honey – Leptosperin and DHA (or dihydroxyacetone). The UMF number is based on the amount of MGO (see our chart for MGO to UMF conversion). Mānuka honey does not need to be UMF certified to be authentic, and our reliance on MGO over UMF allows us to bring you pure, authentic Mānuka honey at the best price possible.
