What Does Manuka Honey MGO Mean? Exploring Certification Methods & the Importance of UMF™


Mānuka honey is known for its purity and potency, but how do you know if the honey you’re buying is the real deal? There are several certification methods used to verify the authenticity and quality of Mānuka honey. In this article, we’ll explore the four main certification methods and explain how each one works. We’ll also introduce the gold standard certification, UMF™, which is recognized worldwide for its extensive criteria. Whether you’re a seasoned Mānuka honey enthusiast or new to the world of pure honey, this article will provide you with valuable information to help you make an informed purchase.

MGO Measurement

Methylglyoxal (MGO) is a bioactive ingredient found in Mānuka honey that represents its potency. The MGO concentration is one of the driving factors that determine which jar of honey consumers choose to buy. Several studies suggest that MGO has antibacterial properties and may contribute to soothing acne-prone skin. However, further research is needed to validate these claims. While MGO is an important factor in measuring Mānuka honey purity, it’s not the only factor to consider.

K-Factor Measurement

K-Factor is another measurement used to gauge the purity of raw Mānuka honey. It focuses on the pollen count within the honey but does not measure the potency. While K-Factor is an exciting new verification method, it has some limitations. It does not take into account MGO, which is considered the most important factor of Mānuka honey. Therefore, it’s important to consider both methods when buying honey and look at the big picture.

MGS Measurement

The Molan Gold Standard (MGS) is an excellent method of gauging the potency and shelf-life of Mānuka honey. It measures both MGO and dihydroxyacetone (DHA) levels in the honey, with the number corresponding to the suggested phenol strength. MGS requires a minimum concentration of <100 mg/kg to determine a grade. DHA is a biochemical precursor to MGO and plays a role in determining the shelf-life of Mānuka honey. While MGS is a reliable method, it does not consider factors such as authenticity and freshness.

BioActive Measurement

BioActive is another method used to measure Mānuka honey purity. It looks at both the peroxide and non-peroxide activity of the honey sample. While hydrogen peroxide is present in small traces within Mānuka honey, it is different from MGO, which is suggested to be the cause of non-peroxide activity. However, BioActive has some drawbacks. The activity from hydrogen peroxide is short-lasting and difficult to measure accurately, making the results potentially unreliable. Additionally, this method does not consider factors such as DHA levels, authenticity, and freshness.

UMF™ Certification

The Unique Mānuka Factor or UMF™ is recognized as the gold standard for Mānuka honey purity verification. It was established in 1998 and focuses on four main factors that contribute to purity: MGO, leptosperin, dihydroxyacetone (DHA), and hydroxymethylfurfural (HMF). Each of these factors plays a role in determining the overall grade or score of the honey. UMF™ grades range from 5+ to 32+, with higher-end grades indicating some of the rarest honey varieties in the world. MGO is the driving factor of potency in UMF™ grades, and it is the most desired factor among buyers.
