Unique MGO™ Manuka Honey is collected from a New Zealand plant called Leptospermum scoparium. For quite some time the unique manuka honey anti-bacterial activity was known and measured by a general measurement of its biological effect.
What was causing the antibacterial activity remained unknown for almost 15 years.

The discovery came from the research group led by Professor Thomas Henle, University of Dresden (Germany).

“We unambiguously demonstrate for the first time that Dietary Methylglyoxal is directly responsible for the anti-bacterial activity of manuka honey”
(reported Molecular Nutrition and Food Research, January, 2008)

So far MGO™ Manuka honey has been the only food in the world found with such a significant Dietary Methylglyoxal content ranging from 20mg/kg to over 800mg/kg. In contrast all other honeys worldwide tested have ranged between 1 to 10 mg/kg, other foods range from 0 to 50mg/kg with coffee and cocoa being the highest. MGO™ 100+ Manuka Honey has been tested and certified to contain at least 100mg/kg of Dietary Methylgloxal.
