This batch (Sample ID 3033815) from New Zealand Honey Co. Limited has been independently tested by Analytica Laboratories Ltd in New Zealand. It carries a UMF grade of 16.3 — UMF is a recognised grading that reflects manuka’s unique non-peroxide activity and gives shoppers a straightforward sense of its strength. The lab measured Methylglyoxal (MGO) at 592 mg/kg; MGO is the compound most commonly used to indicate manuka’s antibacterial potency, so a result above 500 places this honey in the higher-strength category. DHA, a naturally occurring nectar precursor, is what converts into MGO as the honey matures, helping drive that higher MGO level. The leptosperin result of 496 mg/kg is a botanical marker that supports the honey’s authenticity as genuine manuka. With these numbers, this is a robust, high-MGO manuka that the Licensee produces to a consistently high standard — great for people looking for a stronger, premium manuka for uses where higher antibacterial activity is desired, including culinary and topical beauty uses rather than routine sweetening alone.

In short: UMF 16.3 with MGO 592 mg/kg and leptosperin 496 mg/kg — a high-strength, authentic manuka from a trusted New Zealand Honey Co. Limited batch tested by Analytica Laboratories Ltd (New Zealand).
