MGO in Manuka Honey: what it is, and why it matters

What is MGO?

If you know something about Manuka honey, you probably read the name MGO. But what it is?

MGO, short for methylglyoxal, is the natural compound that gives authentic Manuka honey its rare and powerful antibacterial properties. It is the reason why Manuka honey is more than just a sweetener: it’s an act of wellness, a beneficial ally, and a symbol of nature’s strength.

Unlike regular honeys, Manuka’s antibacterial activity doesn’t come from hydrogen peroxide. Instead, it comes from this single, stable molecule: MGO. The higher the MGO level, the greater the honey’s ability to support the immune system and restore balance in the body.

But not all MGO is created equal. While some producers may add synthetic MGO to boost numbers, at Otamatapaio, we rely only on what the bees provide. Our MGO is naturally derived and independently tested: no shortcuts, no compromises.

What the Numbers Mean

MGO is measured in milligrams per kilogram (mg/kg). Here’s how it typically aligns with the UMF™ (Unique Manuka Factor) grading system, which certifies both MGO and other vital natural markers:

Higher MGO levels correspond to more targeted support: UMF 10+ may be ideal for everyday wellness, while UMF 20+ and above are used in more therapeutic or restorative settings.

Not just MGO: discover all natural compounds

While MGO is a key indicator of antibacterial strength, it’s only one part of a much larger story. UMF™ certification ensures not only the MGO level, but also the presence of other essential compounds like Leptosperin (for authenticity), DHA (for long-term potency), and HMF (for freshness).

That’s why Otamatapaio proudly displays the UMF™ mark: it’s your assurance that the MGO in your jar is pure, natural, and part of a holistic profile only found in true New Zealand Manuka honey.
