This certificate (sample ID 501120) shows a high-grade manuka honey from New Zealand Honey Co. Limited, independently tested by Hill Labs in New Zealand. The UMF grade is 20.8 — a strong UMF indicates a robust, characteristic manuka activity above ordinary honeys. Methylglyoxal (MGO) is measured at 882 mg/kg; MGO is the key compound that gives manuka its distinctive antibacterial strength, so a higher MGO means stronger activity. DHA, a compound present in nectar, is the natural precursor that converts into MGO over time (no DHA value is listed here). Leptosperin is reported at 650 mg/kg — this botanical marker supports the honey’s authenticity as genuine manuka. Because this batch has an MGO well above 500 mg/kg and a high UMF, it’s especially suitable for applications where a stronger antibacterial profile is desirable, such as concentrated wellness formulations, advanced beauty and intensive skincare products, or other specialised uses; lower-MGO manuka is generally preferred for everyday food, baking and drinks. New Zealand Honey Co. Limited maintains quality and transparency by using recognised independent testing.

In short: UMF 20.8, MGO 882 mg/kg and leptosperin 650 mg/kg (Hill Labs, New Zealand) confirm a high-strength, authentic manuka well suited to uses that benefit from stronger antibacterial activity.
