All about Manuka Honey

What is it?

New Zealand Manuka Honey has been loved by Global people due to its quality and benefits. It is collected by honeybee from the New Zealand native Manuka tea tree(Leptospermum scoparium). A New Zealand Professor, Peter Molan, discovered that Manuka honey contains unique chemicals including Methylglyoxal(MGO). MGO in Manuka honey shows high level of antibacterial effects.

New Zealand Manuka honey has kept its superior quality by all industrial relatives such as beekeepers, producers, sellers and government. First, All export quality Manuka honey must be qualified by a third-party laboratory that is approved by the New Zealand government. This process has to be done for each produced batches. Secondly, all Manuka honey sellers in New Zealand must be registered and record the export history to track their stock.

Manuka Honey may supports:

Manuka Honey Grades?

Manuka Honey is graded by a government certified laboratory. There are several grading systems like MGS, MGO and UMF. The majority of brands use the UMF grading system which is the most well-known among all systems. However, some brands like PURITI used to certified both MGO and UMF because each system has different criteria.

There are a number of brands in New Zealand. You only need to remember one thing: If the UMF/MGO grade on the label is the same, it meant products have the same quality.

UMF(Unique Manuka Factor)

UMF Grading system is the most well-known and broadly used in the industry. It tests various factors in Manuka honey which not only MGO(Methylglyoxal) but also include Leptosperin, DHA, HMF.

Grade/Purpose MGO(Potency) Leptosperin(mg/kg, Authenticity) DHA(Dihydroxyacetone)(mg/kg, Shelf life) HMF(Hydroxymethylfurfural)(mg/kg, Freshness)
UMF5+/General Purposes 83mg/kg >100mg/kg 150mg/kg <40mg/kg
UMF10+/Everyday Health 261mg/kg >150mg/kg 250mg/kg <40mg/kg
UMF15+/More potent to support Health&Wellness 512mg/kg >200mg/kg 400mg/kg <40mg/kg
UMF20+/More potent to support Health&Wellness 826mg/kg >200mg/kg 500mg/kg <40mg/kg
UMF25+/Higher level of potency with additional nutritional support 1197mg/kg >200mg/kg 500mg/kg <40mg/kg

The higher grade of Manuka honey means the consumer get better health benefits. However, the price will be double when you go with one grade high. We normally recommend choosing for your purposes. For example, If you would like to maintain your health, maybe you only need UMF10+ instead of buying the ultra-premium graded Manuka Honey.

Please refer to our guideline:

  • General Purposes(Sugar substitute): UMF 5+
  • Affordable Choice for maintaining health: UMF10+
  • Premium Grade: UMF15+ and UMF18+
  • Ultra Premium Grade: UMF20+ and UMF22+
  • Superior High Grade: UMF24+ and UMF32+

MGO Grading System
