Manuka Health pioneered MGO testing in 2008 after the ground-breaking discovery that MGO is the elusive ‘magic Manuka ingredient’. Over the past decade we've built MGO into an internationally recognised guide, helping people confidently purchase Manuka honey based on the trusted science of natural MGO potency.
MGO stands for methylglyoxal, the naturally occurring compound that makes Manuka honey so special.
MGO is formed in the honey from Manuka nectar. As the honey ripens, the MGO content can increase. This requires expert knowledge and careful storage, along with precise testing to ensure the potency, quality and purity of the honey.
Not all Manuka honey is created equal and MGO levels can vary greatly. Every jar of our Manuka honey is tested and certified for natural MGO content. The MGO number tells you the level of MGO in your jar of Manuka honey, which is directly related to its potency – simple.

Both MGO and UMF are trusted Manuka honey grading systems, and both measure MGO content.
Manuka Health is a proud member of the UMF association and our honey is both UMF and MGO certified.
Our iconic red MGO mark tells you how much MGO is in the jar (an indicator of its potency and power) and the UMF mark is an independent endorsement of New Zealand origin, quality and grade.
We've provided a handy correlation between MGO and UMF numbers here.
