This batch (Sample ID 4200225) from New Zealand Honey Co. Limited carries a UMF grade of 21.8 and was independently tested by Hill Labs in New Zealand. The laboratory reports MGO at 954 mg/kg — MGO (methylglyoxal) is the compound commonly used to indicate the antibacterial strength of manuka honey — and leptosperin at 520 mg/kg, a botanical marker that helps confirm genuine manuka origin. DHA, a naturally occurring precursor to MGO, is the process by which MGO develops over time, although a specific DHA value is not listed on this certificate. With a UMF of 21.8 and MGO well above 500 mg/kg, this is a higher‑strength manuka honey, well suited where stronger antibacterial activity is preferred — for example, concentrated oral use, immunity‑minded supplements, and targeted skincare or beauty applications. Lower MGO honeys (<500 mg/kg) are often chosen for everyday uses such as baking, drinks and general wellness. New Zealand Honey Co. Limited’s licensed testing shows this is a robust, authentic manuka you can rely on.

In short: UMF 21.8, MGO 954 mg/kg, Leptosperin 520 mg/kg — a high‑strength, independently tested manuka from Hill Labs (New Zealand), ideal when you want a more potent manuka honey.
