Understanding Manuka Honey Certifications: UMF vs. MGO
When shopping for Manuka honey, you'll encounter a variety of symbols and numbers on the labels. The two most prominent are UMF and MGO, which measure different aspects of the honey's quality and potency. Understanding the distinction between these grading systems is key to making an informed choice about your purchase.
Methylglyoxal (MGO) is a naturally occurring compound in Manuka honey that is largely responsible for its powerful antibacterial properties. A product labeled with an MGO rating, such as MGO 400+, indicates that the honey contains a minimum of 400mg of methylglyoxal per kilogram. Manuka Doctor uses MGO ratings extensively across its product range and independently tests each batch to ensure the rating is accurate. This system provides a straightforward measure of the honey's antibacterial strength, making it easy to compare potency between jars.
On the other hand, the Unique Manuka Factor (UMF) is a more comprehensive quality trademark and grading system. Administered by the Unique Manuka Factor Honey Association (UMFHA), the UMF rating requires testing for three key signature compounds: Methylglyoxal (MGO), Dihydroxyacetone (DHA), and Leptosperin. DHA is a precursor to MGO, and Leptosperin is a plant-derived marker unique to Manuka honey, confirming its genuine origin. A UMF-certified honey assures consumers of its potency, authenticity, purity, and freshness. As a UMFHA member (UMF Licence No: 1026), Manuka Doctor offers both MGO-rated and dual-rated UMF/MGO Manuka honey, providing a range of certified options for customers.
The Importance of Independent Testing and Traceability
Beyond the grading systems, what truly guarantees the quality of Manuka honey is independent testing and supply chain transparency. Manuka Doctor prides itself on its 'Hive to Home'® promise, which means they oversee the entire production process from the beehives in New Zealand to the final packaging. This rigorous control ensures that every jar of Manuka Doctor honey is traceable and meets stringent quality standards. Every batch is independently tested in New Zealand laboratories to verify its authenticity and ratings.
In addition, all Manuka honey exported from New Zealand must adhere to the government's strict export laws. These regulations require that the honey is tested for five key markers—four naturally occurring chemicals and one DNA marker—to prove that it is genuine New Zealand Manuka honey. Manuka Doctor's commitment to these standards is a critical factor in its reputation for quality. They also carry other certifications, such as Certified R.A.W., guaranteeing minimal processing, and Kosher certification for certain products.
Choosing the Right Manuka Honey for Your Needs
The best choice of Manuka honey depends on your intended use. For everyday wellness and as a natural sweetener, a lower grade MGO or UMF honey can suffice. For more targeted health benefits, a higher grade is recommended. The chart below provides a simplified comparison of MGO and UMF ratings to help you decide.
| Feature | UMF (Unique Manuka Factor) | MGO (Methylglyoxal) |
|---|---|---|
| Rating Scope | Comprehensive quality mark; measures MGO, DHA, and Leptosperin. | Measures the concentration of methylglyoxal only. |
| Administering Body | Unique Manuka Factor Honey Association (UMFHA). | No single regulatory body; requires third-party testing. |
| Assurance | Guarantees authenticity, potency, purity, and freshness. | Confirms antibacterial strength based on MGO content. |
| Brand Adherence | Requires licensure and adherence to strict standards, including independent auditing. | Brands can test and certify MGO levels themselves or via third-party labs. |
| Cost | Generally commands a higher price due to comprehensive testing and certification costs. | Can be more accessible, but purity outside of MGO is not guaranteed by the rating. |
For those seeking the highest level of assurance regarding authenticity and a full profile of Manuka's unique compounds, UMF-certified honey is the gold standard. However, MGO-rated honey still provides a clear and reliable indicator of antibacterial potency. Manuka Doctor offers both options, allowing you to choose based on your preference and budget.
Conclusion
In summary, Manuka Doctor is indeed UMF certified and is a licensed member of the Unique Manuka Factor Honey Association. However, it is important for consumers to note that they sell products with both the comprehensive UMF rating and the more specific MGO rating, as well as dual-rated jars. When making a purchase, look for the specific certification on the jar and ensure it aligns with your desired level of potency and authentication. Both rating systems provide a degree of quality assurance, but UMF offers a broader guarantee of authenticity, while MGO focuses specifically on antibacterial strength. By checking the label for the UMF or MGO rating and sourcing from reputable retailers, you can be confident you are purchasing genuine, high-quality Manuka honey from New Zealand.
