This certificate covers sample MM308/24B from New Zealand Honey Co. Limited and was independently tested by Hill Labs in New Zealand. The lab reports a UMF grade of 21.1 and an MGO (methylglyoxal) content of 903 mg/kg — MGO is the compound most associated with manuka’s non-peroxide antibacterial activity, so higher numbers indicate stronger antibacterial potency. Leptosperin, a botanical marker used to confirm genuine manuka, is 640 mg/kg in this batch. DHA (dihydroxyacetone) is the natural precursor that converts to MGO as the honey matures; while a DHA value isn’t listed here, it’s useful to know that MGO generally rises over time as DHA converts. With an MGO well above 500, this honey is particularly well suited for situations where higher antibacterial activity is desired (for example, for targeted skincare, beauty formulations, or supplementary use where stronger activity is preferred), whereas lower-MGO manuka is often chosen for everyday food, baking, drinks and general wellness. You can buy with confidence knowing the Licensee provides a thoroughly tested, premium product.

In short: UMF 21.1, MGO 903 mg/kg, Leptosperin 640 mg/kg — a high‑MGO, premium manuka tested by Hill Labs (New Zealand) and well suited where strong antibacterial activity is desired.
