This batch (Sample ID D037915) from Licensee New Zealand Honey Co. Limited was independently tested by Analytica Laboratories Ltd in New Zealand. It carries a UMF grade of 15.8 — the UMF number reflects the honey’s certified non-peroxide activity and overall manuka grading. The laboratory found MGO (methylglyoxal) at 559 mg/kg; MGO is the key compound that gives manuka its distinctive activity, and higher MGO numbers indicate stronger activity. DHA, the natural precursor that converts to MGO in manuka, is not listed on this certificate. Leptosperin is reported at 360 mg/kg, which is a botanical marker used to confirm genuine manuka origin. With an MGO of 559 (above 500), this honey is in the higher-activity range that people commonly choose when they want a more robust manuka profile — for example in concentrated skincare rituals, targeted beauty uses, or where a stronger activity is preferred in personal wellness routines. New Zealand Honey Co. Limited have provided a well-documented, independently tested product you can trust.

In short: UMF 15.8, MGO 559 mg/kg, Leptosperin 360 mg/kg — independently tested by Analytica Laboratories Ltd (New Zealand); a higher-activity manuka from New Zealand Honey Co. Limited, well suited for uses that favour stronger manuka activity.
