The MGO™ rating system is based on the scientific evidence revealed in 2008 by Professor Thomas Henley. It enables our customers to make informed choices about the potency of honey they're buying.
Not all Manuka honey is equal - it is important to know that the level of methylglyoxal can vary greatly in Manuka honey, so you want to be sure you get what you've paid for.
That is why Manuka Health test and certify every batch of MGO™ Manuka Honey to guarantee the level of methylglyoxal present, as indicated by the MGO™ rating on the label. Each batch also undergoes stringent quality testing and is fully traceable right back to the beekeeper it came from.
We developed the MGO™ rating and quality system based on the scientific evidence revealed in 2008 by Professor Thomas Henle and his research group (Technical University of Dresden, Germany) which identified methylglyoxal (MGO) as one of the key compounds found in New Zealand Manuka honey.
The MGO™ Manuka Honey rating and quality system mean our customers can easily make an informed choice of the potency of the honey they're buying. The higher the MGO rating, the higher the grade of honey.
