Which MGO Grade is the right choice for me?


Which MGO Grade is the right choice for me?

What is MGO? What does MGO stand for?

The substance that makes Manuka Honey so unique, is MGO. MGO stands for Methylglyoxal. This stable, antibacterial substance is only found in Manuka Honey in significant quantities. Naturally, the MGO content in the Manuka Honey can vary quite substantially, the highest levels can be more than 1000 mg MGO per 1 kg of Manuka Honey.

MGO spontaneously arises out of Dihydroxyacetone (DHA). A substance which is found in the nectar of the Manuka plant. Biochemically, DHA is a derivative of the glycolytic cycle, a sugar degradation product. When bees bring the nectar, which contains DHA and some smaller amounts of MGO to their hive, the transformation of DHA in MGO slowly continues.

For a long time, it was not understood why Manuka Honey showed this strong antibacterial effect. It was taking until the year 2005 when a German researcher Prof. Dr. Henle of the Technical University of Dresden discovered the magic substance in Manuka Honey. Kerry Paul, who has worked closely with Cosana New Zealand for the past 2 years, worked with Professor Henle’s team to make the scientific discovery public. Kerry Paul is the pioneer of the MGO Manuka Honey Rating System, which is used by the New Zealand Manuka Honey Industry to sort honey by its antibacterial activity.

MGO Rating Scale

Just to gloss over the MGO rating scale, it is a precise and scientific scale that measures the amount (mg) of natural occurring of Methylglyoxal (MGO) within the honey (kg). For example, the rating MGO400+ indicates that there is a minimum of 400mg of Methylglyoxal in 1kg of Manuka Honey.
