Lab results for batch 3031415 from New Zealand Honey Co. Limited show a UMF grade of 15.3, confirming a strong, certified manuka profile. The MGO (methylglyoxal) measure is 534 mg/kg — MGO is the key compound that indicates the honey’s antibacterial potency, so a figure above 500 places this jar in the higher-strength category. Leptosperin is measured at 524 mg/kg, which is the botanical marker used to verify genuine manuka, reinforcing the product’s authenticity. DHA (the naturally occurring precursor that converts into MGO as honey matures) is an important part of that chemistry, though a specific DHA value isn’t listed on this certificate. These results were independently tested by Analytica Laboratories Ltd in New Zealand, adding trusted third-party credibility to the certificate. New Zealand Honey Co. Limited have delivered a clearly labelled, high-MGO manuka that’s particularly well suited to applications where a stronger antibacterial rating is desired — for example, targeted skin and beauty uses, higher-strength wellness routines, and other situations where a high MGO is preferred over everyday table honey.

In short: UMF 15.3 (MGO 534 mg/kg) — an authentic, high-strength manuka from New Zealand Honey Co., lab-tested by Analytica Laboratories Ltd (New Zealand), ideal when you want a higher antibacterial-rated honey.
