This jar from New Zealand Honey Co. Limited (Sample ID 2150524) carries a UMF grade of 15.4 and was independently tested by Hill Labs in New Zealand. The laboratory results show MGO (methylglyoxal) at 535 mg/kg — MGO is the compound used to indicate manuka’s distinctive antibacterial activity, and at this level it sits above the 500 mg/kg mark, making it well suited to uses that benefit from higher antibacterial properties (for example stronger topical skincare and beauty applications, wound care support in non-medical contexts, and times you want a more potent everyday supplement — while still excellent for careful culinary use). Leptosperin is measured at 380 mg/kg, which is a botanical marker used to confirm genuine manuka origin. DHA, the natural precursor that converts to MGO as the honey matures, is often reported on full certificates (no DHA value is shown here). New Zealand Honey Co. Limited sources and presents this premium manuka responsibly, and Hill Labs’ testing adds independent credibility to the label.

In short: UMF 15.4 with MGO 535 mg/kg and leptosperin 380 mg/kg — a premium, independently tested manuka, great for applications that benefit from higher antibacterial activity.
