This batch from New Zealand Honey Co. Limited (Sample ID D032820) carries a UMF grade of 20.9, tested by Analytica Laboratories Ltd in New Zealand. UMF is a recognised measure of manuka’s unique activity, and the laboratory results show a methylglyoxal (MGO) level of 891 mg/kg — MGO is the compound most directly associated with manuka’s antibacterial potency. The certificate also reports a leptosperin level of 797 mg/kg, a botanical marker used to confirm genuine manuka origin. DHA, the natural precursor that converts into MGO over time, is not listed on this certificate. With an MGO well above 500 mg/kg, this honey sits in the higher-strength range and is commonly chosen by shoppers looking for a robust, high-activity manuka for uses such as gut health support, immune-related routines, and concentrated skin and beauty applications; lower MGO honeys (under ~500 mg/kg) tend to be better for everyday food, baking, drinks and lighter wellness or skincare uses. New Zealand Honey Co. Limited sources and labels this lot carefully, and independent testing by Analytica Laboratories Ltd gives you clear numbers to compare.

In short: UMF 20.9 and MGO 891 (with leptosperin 797) indicate a high-activity, genuine manuka—ideal if you want a strong, high-MGO honey from a trusted New Zealand source.
