What is MGO?

MGO Manuka Power

MGO stands for methylglyoxal, the naturally occurring compound that makes Manuka honey so special.

Our research partner - Professor Thomas Henle (University of Dresden) and his team - discovered MGO as the magic ingredient in Manuka honey, a discovery long sought after in the science world.

In 2008 Manuka Health pioneered MGO testing as a more precise and reliable method of grading Manuka honey, based on this ground-breaking research.

Not all Manuka honey is created equal and MGO levels can vary greatly.  Every jar of Manuka Health MGO Manuka Honey is tested and certified for natural MGO content. The MGO number tells you how much MGO is in your jar of honey – simple.

The amount of MGO in your Manuka honey is directly related to its potency

MGO and  UMF

Both MGO and UMF are trusted Manuka honey grading systems, and both measure MGO (methylglyoxal) content. Testing for MGO levels is important as they can vary greatly – not all Manuka honey is equal.

The MGO Manuka Honey grading system is a precise and reliable test that simply and directly reflects the MGO content of the honey. The higher the MGO content the higher the grade of honey.

We've provided a handy correlation between MGO and UMF numbers here. 

Manuka Health is also a member of the UMF Honey Association

As part of beautiful new packaging design, we are adding elements to reassure our customers on authenticity, potency & purity.  Manuka Health now proudly carries both the MGO and UMF rating systems - we believe using both MGO and UMF on our labels offers the customer the ultimate in transparency and reassurance of quality and origin. Our iconic red MGO double hex mark gives the exact content of MGO in each jar (an indicator of its potency and power) and the UMF mark gives an added endorsement authenticating New Zealand origin. Combined, these trusted symbols solidify Manuka Health’s position as a trusted expert in Manuka honey. With the rollout of our premium new packaging we have also optimized the potency of our flagship MGO range. Our MGO 100+ will increase in natural MGO content to 115+ our 250+ to 263+ and our 550+ to 573+. This means even more MGO Manuka power in every spoonful. See table across for a guide to our new MGO ratings with the corresponding UMF grade.
