UMF™ and MGO measure the strength of Manuka honey. Higher UMF™ ratings correspond to higher MGO levels and greater antibacterial activity. MGO measures the concentration of methylglyoxal, while UMF™ is a broader grading system that also tests authenticity markers like leptosperin and DHA. Higher UMF™ ratings correspond to higher MGO levels.
What Is UMF™?
UMF™ (Unique Manuka Factor) is an independent quality grading system that measures the concentration of signature Manuka compounds. Higher UMF™ ratings indicate higher potency.
What Is MGO?
MGO (Methylglyoxal) is the naturally occurring compound in Manuka honey responsible for its antibacterial properties. UMF™ and MGO are directly related — higher UMF™ means higher MGO levels.
