While Manukora is still UMF certified as a company, in 2022, we opted to remove the UMF certification from our labels and focus on MGO grading certification to avoid confusion between numbers.MGO is one of the key bioactive compounds in Mānuka honey. The higher the MGO, the higher the other key bioactives such as Leptosperin (a key antioxidant) which we also test for.UMF is simply a different system to measure the same bioactive compounds in Mānuka (MGO, DHA, HMF, Leptosperin). We test every single one of these (+ more such as glyphosate residue) at third-party labs and make them available on our QR trace system on every product.As a result, we no longer show a UMF value on our lab reports but you can see all of the test results for the key compounds including NPA (non peroxide activity).The NPA number is the exact same as the UMF number.UMF/NPA 5 = MGO83UMF/NPA 10 = MGO263UMF/NPA 15 = MGO514UMF/NPA 20 = MGO829You can read more about the difference between UMF and MGO  and why we only carry the MGO certification here on our blog.
