Decoding the MGO Rating System on Manuka Honey
Manuka honey is recognized globally for its special qualities, but its labeling can be confusing. The letters 'MGO' followed by a number, such as MGO 250, indicate the honey's quality and strength. This number represents the concentration of methylglyoxal, a powerful compound naturally present in Manuka honey that gives it exceptional antibacterial qualities. Unlike the peroxide activity found in most other honeys, Manuka's MGO content is stable and doesn't degrade easily, making it more effective for various therapeutic applications. The specific rating of MGO 250+ means that for every kilogram of honey in the jar, there is a minimum of 250 milligrams of methylglyoxal. This provides a moderate to high level of potency, suitable for both daily immune support and more targeted seasonal wellness needs.
The Science Behind Methylglyoxal (MGO)
Methylglyoxal doesn't just appear in the honey; it is formed from another compound called dihydroxyacetone (DHA). DHA is naturally present in high concentrations in the nectar of the New Zealand Manuka bush (Leptospermum scoparium). After the bees collect the nectar and turn it into honey, the DHA slowly converts into MGO during a maturation period that can last for 12 to 24 months. This is why a high-grade Manuka honey that has been properly aged will have a higher MGO concentration and, consequently, greater antibacterial activity. Factors like the intensity of the Manuka bloom and whether bees gathered nectar solely from Manuka or also from other flowers can influence the final MGO level. Independent laboratories test and certify each batch of honey to ensure the MGO rating is accurate and meets strict quality standards. This process ensures consumers receive an authentic and high-quality product.
Practical Benefits of MGO 250 Manuka Honey
An MGO 250+ rating signifies a versatile, medium-strength Manuka honey. It offers a balance between cost-effectiveness and therapeutic potency, making it a popular choice for many consumers.
Oral Health: Research has indicated that Manuka honey may help reduce plaque buildup and inflammation in the gums. Using a medium-strength MGO 250+ honey can support overall oral hygiene.
Digestive Support: MGO 250+ honey is suitable for maintaining digestive balance. Its antibacterial properties may help soothe digestive discomfort and support a healthy gut microbiome.
Immune System Boost: For those looking for extra support during seasonal changes, MGO 250+ is an excellent choice. A daily spoonful can help fortify the immune system and support overall well-being.
Topical Applications: While higher grades are often recommended for severe wounds, MGO 250+ is effective for soothing and protecting minor cuts, scrapes, and burns. Its antibacterial and anti-inflammatory properties promote healing and prevent infection.
MGO vs. UMF: Understanding the Difference
Another certification you might encounter is UMF (Unique Manuka Factor). While MGO is a scientific measurement of a single compound, UMF is a more comprehensive quality trademark managed by the UMF Honey Association. It evaluates four key compounds to ensure authenticity, quality, and purity.
| Feature | MGO Rating | UMF Rating |
|---|---|---|
| Measurement | Quantifies the concentration of a single compound: Methylglyoxal (MGO). | A comprehensive assessment of four key compounds, including MGO, DHA, leptosperin, and HMF. |
| Indicates | The honey's antibacterial potency and strength. | The honey's authenticity, purity, freshness, and potency. |
| Regulation | Not regulated as a formal standard, but most credible producers use independent labs for verification. | A tightly regulated trademark by the UMF Honey Association in New Zealand. |
| Typical Equivalence | MGO 250+ is roughly equivalent to UMF 10+. | Higher UMF grades correlate with higher MGO levels. |
| Use Case | Useful for customers primarily concerned with antibacterial strength. | Preferred by customers who want a broader assurance of authenticity and quality. |
How to Choose the Right MGO Level
The right MGO level depends entirely on the intended use. For daily consumption and maintenance, a lower MGO rating (e.g., MGO 100+) may suffice. However, if you are seeking a honey with more pronounced therapeutic properties, MGO 250+ provides a significant step-up in antibacterial strength. For intensive support or targeted applications like wound care, you might consider even higher ratings such as MGO 550+ or higher. Always ensure you are purchasing from a reputable brand that provides independent lab certifications to guarantee the accuracy of the MGO rating.
Conclusion
The MGO 250+ rating on a jar of Manuka honey is a direct and scientifically validated measure of its methylglyoxal content and antibacterial potency. It signifies that the honey contains a minimum of 250mg of MGO per kilogram, making it a potent choice for supporting general wellness, immune function, and digestive health. While other rating systems like UMF offer a more holistic assessment of quality, the MGO rating provides clear, straightforward information on the honey's key active compound. By understanding what MGO 250 means, consumers can make an informed decision and select a Manuka honey that best aligns with their health and wellness goals.
What is MGO in Manuka Honey? Methylglyoxal explained
Frequently Asked Questions
What does MGO stand for on Manuka honey? MGO stands for methylglyoxal, a naturally occurring antibacterial compound found in high concentrations in Manuka honey that is responsible for its unique properties.
Is MGO 250+ a good rating for Manuka honey? Yes, an MGO 250+ rating is considered a good, medium-strength potency, suitable for daily wellness, immune support, and digestive balance.
What is the difference between MGO and UMF ratings? MGO is a scientific measure of the methylglyoxal content, while UMF is a more comprehensive, trademarked grading system that measures several unique compounds to verify authenticity, including MGO.
Can MGO 250+ Manuka honey be used for digestive health? Yes, Manuka honey with an MGO 250+ rating is well-suited for supporting digestive health and maintaining a healthy gut microbiome.
How is the MGO level of Manuka honey determined? The MGO level is determined through independent laboratory testing using techniques like High-Performance Liquid Chromatography (HPLC) to accurately measure the methylglyoxal concentration.
Why is Manuka honey with a higher MGO rating more expensive? Honey with higher MGO ratings is rarer and requires nectar from specific Manuka flowers and longer maturation periods to reach higher concentrations, making it more potent and costly to produce.
Can I use MGO 250+ Manuka honey for wound care? Yes, MGO 250+ has reliable antibacterial potency suitable for treating minor cuts, scrapes, and burns, though higher grades may be recommended for more serious wounds.
Does MGO level affect the taste of Manuka honey? Yes, higher MGO levels often correspond with a richer, more intense, and sometimes earthier or slightly bitter flavor profile compared to lower-grade Manuka honey.
