This batch (Sample ID 1280725) from New Zealand Honey Co. Limited has been independently tested by Hill Labs in New Zealand and shows a UMF grade of 28.2 with an MGO level of 1463 mg/kg and a leptosperin content of 1290 mg/kg. UMF is a recognised grading that reflects manuka’s unique non‑peroxide activity; the high UMF here indicates a premium, very potent manuka product. MGO (methylglyoxal) is the compound most closely associated with manuka’s antibacterial strength — the higher the MGO, the stronger that activity. DHA (dihydroxyacetone) is the natural precursor found in nectar that converts into MGO as the honey matures (no DHA value was provided for this sample). Leptosperin is a botanical marker used to confirm genuine manuka; the reported 1290 mg/kg supports authenticity. With MGO well above 500 mg/kg, this honey is suited to applications where higher antibacterial activity is desired — many customers choose such high‑strength manuka for advanced skincare and beauty uses, as a potent everyday wellness option, or whenever a stronger grade is preferred. New Zealand Honey Co. Limited have provided a top‑quality, carefully tested product you can feel confident about.

In short: UMF 28.2, MGO 1463 mg/kg and leptosperin 1290 mg/kg from Hill Labs (New Zealand) signal a very high‑strength, genuine manuka ideal for those seeking a premium, potent jar.
