FAQs - Q: Difference between UMF, MGS and MGO

UMF™ is the standard of measure used by the UMFHA – Unique Manuka Factor Honey Association. A UMF™ grading test measures Leptosperin, MGO (Methylglyoxal) DHA and HMF.

MGS measures MGO and DHA levels in Manuka Honey between 5+ and 30+ and the number assigned correlates to the equivalent phenol strength of the Manuka honey antibacterial activity. MGS will not provide a grade for Manuka honey which has MGO levels of less than 100 mg/kg.

MGO measures the methylglyoxal level in Manuka Honey. MGO is the strength and energy within Manuka Honey and is what makes it effective for health and wellbeing. MGO is not a technical grading system. It is a measure of the MG (methylglyoxal) level in the Honey.
