This batch from New Zealand Honey Co. Limited (Sample ID D052L15) was independently tested by Hill Labs in New Zealand. It carries a UMF grade of 15.7 — a recognised measure of manuka’s unique activity — and an MGO (methylglyoxal) level of 556 mg/kg. MGO is the compound most commonly used to indicate antibacterial strength in manuka; higher MGO numbers show higher antibacterial activity. DHA (dihydroxyacetone) is the natural precursor that converts into MGO as honey matures (no DHA value is listed on this certificate). The laboratory also measured Leptosperin at 520 mg/kg, a botanical marker that supports the genuine manuka origin of the honey. With MGO over 500, this honey sits in the higher potency range and is well suited to shoppers looking for a stronger manuka — popular for targeted wellness, beauty and skin care applications, and other uses where higher antibacterial strength is desired. New Zealand Honey Co. Limited has provided a carefully tested product you can feel confident about.

In short: UMF 15.7 with MGO 556 mg/kg and Leptosperin 520 mg/kg (tested by Hill Labs, New Zealand) — a higher‑potency, genuine manuka honey from New Zealand, ideal when you want stronger antibacterial activity in your jar.
