This batch (Sample ID 3044J/15) from New Zealand Honey Co. Limited has been independently tested by Analytica Laboratories Ltd in New Zealand and shows a UMF grade of 15.8, MGO 561 mg/kg and leptosperin 503 mg/kg. UMF is a recognised grading that combines several markers to indicate authentic, high-quality manuka honey—MGO (methylglyoxal) is the compound most linked to manuka’s antibacterial rating, while DHA is the natural precursor that converts into MGO over time. Leptosperin is a botanical marker used to confirm the honey is genuine manuka. With an MGO of 561 mg/kg and a UMF around 16, this is a higher-strength manuka that many people select when they want a stronger antibacterial rating—for example, for specialised beauty and skin-care formulations, higher-strength wellness routines, or products where a robust manuka profile is preferred. New Zealand Honey Co. Limited offers this well-tested honey with transparent lab backing, so you can choose with confidence.

In short: UMF 15.8 with MGO 561 mg/kg and leptosperin 503 mg/kg (tested by Analytica Laboratories Ltd, New Zealand) — a higher-strength, authentic manuka honey ideal for shoppers seeking a robust manuka profile.
