What Does MGO Mean? A Simple Guide to Understanding Mānuka Honey Strength
Share
If you've ever looked at a jar of mānuka honey, you've probably noticed a number on the label such as MGO 100+, MGO 300+, or MGO 850+. For many people, that raises an immediate question:
What does MGO actually mean?
It's one of the most common questions asked by people exploring mānuka honey for the first time. Understanding MGO can help you compare products, choose the right honey for your needs, and purchase with greater confidence.
At Manuka Hunters, we believe understanding what you're buying is just as important as the honey itself. Here's a simple guide to what MGO means and why it matters.
What Is MGO?
MGO stands for methylglyoxal, a naturally occurring compound found in mānuka honey.
While all honey contains a variety of natural compounds, mānuka honey is unique because it contains significantly higher levels of methylglyoxal than most other honey varieties.
This compound develops naturally over time from another substance found in mānuka nectar called DHA (dihydroxyacetone).
As the honey matures, DHA gradually converts into MGO, creating the levels that are measured and displayed on the label.
In simple terms:
The MGO number tells you how much methylglyoxal is present in the honey.
Why Is MGO Important?
MGO has become one of the most widely recognised ways of measuring mānuka honey strength.
Because it can be scientifically tested and quantified, it gives consumers a reliable benchmark when comparing different products.
The higher the MGO rating, the greater the concentration of methylglyoxal present in the honey.
For example:
- MGO 100+ contains at least 100mg of methylglyoxal per kilogram of honey
- MGO 300+ contains at least 300mg per kilogram
- MGO 550+ contains at least 550mg per kilogram
- MGO 850+ contains at least 850mg per kilogram
These ratings provide a simple way to understand relative strength across different mānuka honey products.
Does Higher MGO Mean Better Honey?
Not necessarily. One of the biggest misconceptions about mānuka honey is that higher MGO automatically means "better." In reality, the best strength depends on how you intend to use it.
Many people enjoy lower and mid-range MGO honey as part of their daily routine because it offers the distinctive flavour and characteristics of mānuka honey while remaining versatile and approachable.
Higher MGO products are often chosen by consumers looking for stronger grades and are generally considered more premium due to their rarity and testing requirements.
Rather than asking "What is the best MGO?", a more useful question is:
What MGO level is right for me?
How Is MGO Measured?
MGO levels are determined through laboratory testing. Samples from each batch of honey are analysed to determine the concentration of methylglyoxal present.
This testing provides an objective measurement rather than relying on estimates or assumptions.
At Manuka Hunters Science Page, you'll find more information about the scientific testing that supports authentic mānuka honey grading.
Independent testing helps ensure consumers receive accurate information about the honey they purchase.
MGO vs UMF: What's the Difference?
Another common source of confusion is the difference between MGO and UMF.
Both systems are used to describe mānuka honey, but they measure slightly different things. MGO measures the concentration of methylglyoxal directly.
UMF (Unique Mānuka Factor) is a broader grading system that incorporates multiple markers, including MGO and additional compounds associated with authenticity.
Both systems are widely recognised within the mānuka honey industry. For many consumers, MGO provides a straightforward and easy-to-understand measure of strength.
Why Authenticity Matters
MGO is important, but it is only one part of the story. A genuine mānuka honey product should also be supported by testing that verifies authenticity.
New Zealand has developed strict scientific standards for mānuka honey, helping ensure products meet recognised criteria for origin and composition. This is why purchasing from reputable producers matters.
Authenticity, traceability, and independent testing all contribute to consumer confidence.
At Trace Your Honey, customers can learn more about the journey behind their honey and the commitment to transparency that supports every jar.
Choosing the Right MGO for Everyday Use
For many households, mānuka honey is part of everyday life. It might be added to breakfast, stirred into warm drinks, drizzled over yoghurt, or incorporated into simple recipes.
When choosing a product, it helps to think about how often you'll use it and what role it will play in your routine.
Many consumers find lower or mid-range MGO options ideal for regular use, while higher grades may be selected for specific preferences or gifting occasions.
The most important factor is choosing a product that aligns with your lifestyle and goals.
Frequently Asked Questions About MGO
· Is MGO naturally occurring?
Yes. MGO develops naturally from DHA found in mānuka nectar.
· Can MGO levels vary?
Yes. Natural seasonal conditions, flowering patterns, and nectar composition can all influence MGO levels.
· Does all mānuka honey contain MGO?
Yes, although the concentration varies between products.
· Is a higher MGO always necessary?
No. Many people choose lower or mid-strength mānuka honey for everyday enjoyment and routine use.
· How can I verify authenticity?
Look for products that provide transparency, testing information, and traceability.
Understanding the Number Behind the Label
MGO is one of the simplest ways to understand mānuka honey strength. While it is not the only factor that matters, it provides a useful guide when comparing products and selecting the right honey for your needs.
The key is understanding that MGO is not about finding the highest number possible. It is about choosing a product that fits your routine, preferences, and intended use.
When combined with authenticity, testing, and traceability, MGO becomes a valuable tool for making informed decisions.
