This independent certificate (Sample ID 1280824) from Hill Labs in New Zealand shows a UMF grade of 28.8, with MGO (methylglyoxal) measured at 1514 mg/kg and Leptosperin at 1320 mg/kg. UMF is a recognised grading that reflects the non‑peroxide antibacterial characteristics of manuka honey and brings together key markers such as MGO. MGO is the compound that indicates antibacterial strength, while DHA (dihydroxyacetone) in the nectar is the natural precursor that converts into MGO as the honey matures. The high MGO value here (well over 500 mg/kg) places this as a high‑strength manuka — commonly chosen when a robust antibacterial component is preferred, for example in targeted skin and beauty routines, wound-care topical use, or by people seeking a potent option for gut or immunity‑supporting wellness routines. The strong Leptosperin result supports the botanical authenticity of this jar. Our licensee, New Zealand Honey Co. Limited, works with reputable independent testing to ensure consistent, genuine product quality you can trust.

In short: UMF 28.8 with MGO 1514 mg/kg and Leptosperin 1320 mg/kg — a high‑strength, authentic New Zealand manuka honey from Hill Labs testing, ideal when you want a potent option.
