UMF vs MGO: What's the Difference?
A Complete Guide to Choosing Authentic Manuka Honey
If you've ever shopped for Manuka honey, you've probably noticed labels displaying UMF or MGO ratings. Many people wonder which one is more important and whether one is better than the other.
The truth is that both UMF and MGO are important, but they measure different aspects of authentic Manuka honey.
This guide explains what each rating means and how to choose the right Manuka honey for your needs.
What Is UMF?
UMF stands for Unique Manuka Factor.
It is an independent quality certification administered by the Unique Manuka Factor Honey Association (UMFHA) in New Zealand.
A UMF rating confirms that the honey:
- Is genuine New Zealand Manuka honey
- Meets strict quality standards
- Has been independently tested
- Is free from contaminants
- Contains the naturally occurring compounds expected in authentic Manuka honey
When you purchase UMF-certified honey, you know exactly what you're getting.
What Is MGO?
MGO stands for Methylglyoxal.
MGO is the naturally occurring compound responsible for many of Manuka honey's unique antibacterial properties.
Unlike regular honey, Manuka honey contains much higher concentrations of MGO.
The higher the MGO level, the greater the antibacterial activity measured in laboratory testing.
Are UMF and MGO the Same?
Not exactly.
Think of it this way:
UMF is a quality certification.
MGO is a laboratory measurement of one important compound within the honey.
UMF measures multiple characteristics, while MGO measures only the concentration of methylglyoxal.
UMF vs MGO Comparison
| UMF Rating | Approximate MGO Level |
|---|---|
| UMF 5+ | 83 mg/kg |
| UMF 10+ | 263 mg/kg |
| UMF 15+ | 514 mg/kg |
| UMF 20+ | 829 mg/kg |
| UMF 22+ | 971 mg/kg |
| UMF 23+ | 1042 mg/kg |
| UMF 25+ | 1200+ mg/kg |
Actual MGO values may vary slightly between batches.
Which Rating Should You Trust?
The best choice is Manuka honey that displays both a UMF certification and an MGO value.
This provides confidence that:
- The honey is authentic.
- It has been independently tested.
- The antibacterial activity has been verified.
Which UMF Rating Should You Choose?
UMF 5+ to UMF 10+
Ideal for:
- Everyday use
- Adding to tea
- Smoothies
- General wellness
UMF 15+
A popular choice for people looking for higher-strength Manuka honey.
Suitable for:
- Daily wellness
- Seasonal support
- Premium quality
UMF 20+ to UMF 25+
These are among the highest grades available.
Many customers choose these premium strengths because of their exceptionally high natural MGO levels and rigorous UMF certification.
Why Is UMF Certification Important?
Unfortunately, not all products labeled "Manuka Honey" are independently certified.
UMF certification provides reassurance that the honey:
- Comes from New Zealand
- Meets strict testing standards
- Contains genuine Manuka markers
- Is traceable back to the producer
This makes it one of the most trusted certification systems in the world.

Frequently Asked Questions
Is higher MGO always better?
Not necessarily. Higher MGO indicates greater antibacterial activity, but the best choice depends on your intended use and budget.
Can two UMF 20+ jars have different MGO values?
Yes.
Natural honey varies slightly from batch to batch. Both products can still meet UMF certification standards.
Does MGO increase over time?
Interestingly, yes.
Fresh Manuka honey naturally contains dihydroxyacetone (DHA), which gradually converts into MGO as the honey matures.
Final Thoughts
Both UMF and MGO play an important role when selecting authentic Manuka honey.
- UMF guarantees authenticity and quality through independent certification.
- MGO measures the concentration of methylglyoxal, one of Manuka honey's most important naturally occurring compounds.
Choosing a product that displays both UMF certification and an MGO value gives you confidence that you're purchasing genuine, premium-quality New Zealand Manuka honey.
