Honey has long been cherished for its sweetness and natural health benefits, but not all honey is created equal. Among the many varieties, Manuka honey stands out as a premium product with unique properties that set it apart from conventional honey. Originating from New Zealand and parts of Australia, Manuka honey is derived from the nectar of the Manuka tree (Leptospermum scoparium). Its special antibacterial, anti-inflammatory, and healing properties make it highly sought after.
What Makes Manuka Honey Different?
Unlike regular honey, which contains hydrogen peroxide as a natural antibacterial agent, Manuka honey has non-peroxide antibacterial activity (NPA). This means its antimicrobial effects remain stable even when exposed to heat, light, or enzymatic activity, unlike ordinary honey, which loses potency under such conditions.
The secret behind Manuka honey’s unique properties lies in its high concentration of Methylglyoxal (MGO), a naturally occurring compound responsible for its powerful antibacterial effects. The higher the MGO content, the stronger the honey’s antibacterial potential.
To measure and certify its quality, Manuka honey is graded using two main rating systems: UMF (Unique Manuka Factor) and MGO.
Understanding the UMF and MGO Scales
The UMF (Unique Manuka Factor) rating is a globally recognized grading system developed by the UMF Honey Association (UMFHA) in New Zealand. This system assesses the authenticity and potency of Manuka honey based on key bioactive compounds, including:
Methylglyoxal (MGO) – the main antibacterial component
Dihydroxyacetone (DHA) – a precursor to MGO found in Manuka nectar
Leptosperin – a marker unique to genuine Manuka honey
The UMF scale typically ranges from UMF 5+ to UMF 25+, with higher numbers indicating greater antibacterial potency.
To ensure authenticity, genuine UMF Manuka honey will always have the UMF logo and license number from the UMF Honey Association.
The MGO (Methylglyoxal) scale is a straightforward way of measuring the concentration of Methylglyoxal in Manuka honey. It is directly linked to the honey’s antibacterial strength.
Unlike the UMF rating, which considers multiple factors, the MGO scale focuses solely on the Methylglyoxal content. However, high MGO levels often correlate with a strong UMF rating.
How to Choose the Best Manuka Honey?
Look for the UMF or MGO certification – Avoid brands that do not specify these ratings, as they may be low in bioactive compounds.
Check the UMFHA license number – This guarantees authenticity and quality.
Consider the intended use – For general wellness, UMF 10+ or MGO 250+ is suitable, while UMF 20+ or MGO 850+ is best for medicinal purposes.
Conclusion
Manuka honey is far more than just a sweetener — its unique MGO content and UMF grading system make it a powerful natural remedy. Whether used for wound healing, immune support, or gut health, it remains one of nature’s most potent superfoods. When buying Manuka honey, always check for the UMF or MGO certification to ensure you’re getting genuine, high-quality honey with proven health benefits.
