This jar from New Zealand Honey Co. Limited is UMF 16, a strong, premium manuka grade tested by Analytica Laboratories Ltd in New Zealand (sample ID MM292/24). The laboratory report shows MGO 572 mg/kg — MGO is the compound most associated with manuka’s non‑peroxide antibacterial activity, so a higher MGO number indicates higher antibacterial potency. Leptosperin is 551 mg/kg, which is a botanical marker used to confirm genuine manuka origin. DHA (dihydroxyacetone) is the nectar precursor that slowly converts into MGO during storage, helping explain how MGO levels develop over time. Because this honey’s MGO is above 500 mg/kg, it’s commonly chosen for situations where higher antibacterial activity is desired — for example, targeted gut-health and immunity supplements, specialised beauty or wound‑care formulations, and concentrated skincare uses — while lower MGO manuka (<500) is often preferred for everyday food, drinks, baking and general skincare. New Zealand Honey Co. Limited offers this batch as a premium option for shoppers looking for higher-activity manuka backed by independent testing.

In short: UMF 16 (MGO 572 mg/kg, Leptosperin 551 mg/kg) — independently tested by Analytica Laboratories Ltd (New Zealand); a higher‑activity manuka that’s popular for more targeted uses.
