What is NPA?
NPA denotes non-peroxide activity, which confers antibacterial activity to Mānuka Honey. It directly relates to the concentration of MGO and it corresponds with the UMF™ equivalent grade of honey eg. 5+, 10+, 15+.
While this is also not an established grading system it is mentioned as countries including the UK most commonly understand the NPA value.
UMF | MGO | NPA |
16+ | 570 | 16 |
18+ | 690 | 18 |
20+ | 830 | 20 |
