Manuka honey from New Zealand New Zealand Manuka honey is honey obtained from the nectar of the flowers of the Manuka bush, which is endemic to New Zealand. Among the many honeys, it is said to have antibacterial and immune-boosting effects, and has been eaten in New Zealand for a long time to maintain daily health. What is Methylglyoxal? Methylglyoxal (MGO) is a natural compound that is an antibacterial component of Manuka honey. ​ MGO and UMF are used to evaluate the antimicrobial components of Manuka honey. MGO and UMF are both reliable Manuka honey grading systems, and both measure methylglyoxal content. The MGO Manuka Honey Grading System is an accurate and reliable test that reflects the methylglyoxal content of honey easily and directly. The higher the content of methylglyoxal, the higher the grade of honey. NatureTouched's Manuka Honey uses the MGO Manuka Honey Grading System to evaluate its antimicrobial content. ​ The MGO figure specifically shows how many mg of methylglyoxal is contained in 1 kg of Manuka honey. Nature Touched Manuka Honey MG 30+ is Manuka honey that contains more than 30 mg of the antibacterial ingredient methylglyoxal in 1 kg.
