What is UMF™?

The Unique Mānuka Factor (UMF™) is the gold standard for measuring mānuka honey's therapeutic potency. Developed in New Zealand, this grading system measures the presence of key compounds that give mānuka honey its unique healing properties.

The science behind the numbers

UMF™ grading measures three critical components:

Methylglyoxal (MGO) — The primary antibacterial compound

Dihydroxyacetone (DHA) — The precursor to MGO

Leptosperin — A compound unique to mānuka honey that ensures authenticity
