This certified Mānuka honey (Sample ID 2NZH15), sold by New Zealand Honey Co. Ltd, was independently tested by Analytica Laboratories Ltd in New Zealand. It carries a UMF 15 grade — UMF is a recognised measure of the honey’s distinctive non-peroxide activity and overall quality — and the laboratory reports an MGO (methylglyoxal) level of 514 mg/kg, which is the common indicator of antibacterial activity in Mānuka. Leptosperin is measured at 489 mg/kg, a botanical marker that helps confirm this is genuine Mānuka honey from New Zealand. The certificate does not list DHA; DHA is the natural precursor to MGO and, when reported, helps indicate how the honey may mature over time. With an MGO above 500 mg/kg, shoppers often choose this strength for higher‑potency uses such as general immunity and gut-supporting routines, beauty and skincare, or for topical care where stronger antibacterial properties are preferred. The presence of a UMF grade and independent lab testing demonstrates clear quality control, and New Zealand Honey Co. Ltd’s standing as the UMF Licensee is a positive sign of provenance and consistency.

In short: UMF 15 Mānuka honey (MGO 514 mg/kg, Leptosperin 489 mg/kg), independently tested in New Zealand — a high‑strength, trusted option for those seeking stronger Mānuka potency.
