This jar from New Zealand Honey Co. Limited (sample ID 3150125) has a UMF grade of 15.9, independently tested by Hill Labs in New Zealand. UMF is a recognised grading that reflects manuka’s non‑peroxide activity and is closely related to MGO (methylglyoxal) — the compound most associated with manuka’s antibacterial strength. This sample shows MGO 564 mg/kg, which is above the 500 mg/kg threshold and indicates a higher antibacterial rating; DHA (the natural precursor that can convert to MGO over time) is not listed on this certificate. The leptosperin result of 490 mg/kg is a clear botanical marker confirming genuine manuka origin. Taken together, these lab results give confidence in both authenticity and potency. New Zealand Honey Co. Limited has provided a nicely balanced, reliably tested product — robust enough for uses where higher antibacterial activity is desired, while still delivering the flavour and quality you expect from premium manuka.

In short: UMF 15.9 with MGO 564 mg/kg and leptosperin 490 mg/kg (Hill Labs, New Zealand) — a genuine, higher‑MGO manuka well suited to strength‑focused uses such as immunity and beauty support, and applications where antibacterial properties are valued.
