UMF

UMF stands for ‘Unique Manuka Factor’ and it is an internationally registered trademark that can be used only by licensed users who meet set criteria which include auditing and monitoring to ensure the product is natural, unadulterated, Manuka honey that has the unique non-peroxide antibacterial activity and is true-to-label claim.

Manuka Honey is independently tested in an accredited laboratory for its antibacterial UMF®. The UMF rating system was developed to measure the activity level of Manuka Honeys. The ideal UMF rating varies depending on your purpose.

Rather than measuring the methylglyoxal content like the MGO methodology, the UMF rating actually tests the antibacterial performance of a honey and compares it to phenol, a disinfectant.
