Demystifying Manuka Honey Grades
When shopping for Manuka honey, you will notice different grading systems displayed prominently on the labels. The most common and direct of these is the MGO system, which stands for Methylglyoxal. This compound is the key marker for Manuka honey's unique and potent antibacterial activity, which sets it apart from regular honey. The number that follows 'MGO' indicates the minimum concentration of methylglyoxal found in each kilogram of honey. Therefore, a jar labeled 850+ MGO contains at least 850 milligrams of methylglyoxal per kilogram, representing an exceptionally high concentration. This places it in the premium, high-strength category, suitable for targeted health support and therapeutic applications rather than daily, general use.
The Role of Methylglyoxal (MGO)
Methylglyoxal does not occur naturally in the nectar of the Manuka flower but instead develops over time from another compound called dihydroxyacetone (DHA). This conversion process is influenced by factors like the honey's age and storage conditions. High levels of DHA in the original Manuka nectar are what make high-grade Manuka honey so potent. The antimicrobial properties of MGO are stable and resist the enzymatic breakdown that affects the hydrogen peroxide-based antibacterial activity found in most other honeys.
Benefits of High-Potency 850+ MGO Manuka
The elevated MGO level in 850+ Manuka honey offers enhanced wellness support, making it ideal for various therapeutic applications. Its strength provides more intensive antibacterial and anti-inflammatory effects.
- Targeted Immune Support: During periods of seasonal change or when your body needs extra resilience, a high-grade honey like 850+ MGO can provide potent support for the immune system.
- Advanced Digestive Health: The potent antibacterial properties of high-MGO Manuka honey are often used to support a healthy gut microbiome and may assist with managing digestive issues.
- Intensive Wound and Skin Care: Applied topically, this premium honey can help with wound healing by fighting bacteria and reducing inflammation. It is used for burns, minor cuts, and skin irritations.
- Soothing Sore Throats: For bacterial coughs and severe sore throats, the strong antimicrobial effects of high-potency Manuka can provide significant relief.
MGO vs. UMF: What's the Difference?
While MGO is a straightforward, single-metric measurement, the Unique Manuka Factor (UMF) is another respected grading system that provides a more comprehensive picture of Manuka honey's quality and authenticity.
Comparison Table: MGO vs. UMF Grading Systems
| Feature | MGO Grading | UMF Grading |
|---|---|---|
| Measurement Focus | Measures the specific compound Methylglyoxal (MGO) in mg/kg. | Measures four key compounds: MGO, Leptosperin, DHA, and HMF. |
| Authenticity | Assures the level of a single potent antibacterial compound. | Verifies broader quality, purity, and authenticity markers from the Manuka plant. |
| Measurement Scale | A continuous scale, such as 100+, 400+, 850+, etc.. | A discrete scale, such as UMF 5+, UMF 10+, UMF 15+, etc., where higher numbers don't scale linearly. |
| Trust and Verification | Reliable for potency when from a transparent brand with third-party testing. | Administered by the UMF Honey Association in New Zealand, providing certified quality assurance. |
| Equivalency | MGO 826+ is approximately equivalent to UMF 20+. | UMF 20+ is approximately equivalent to MGO 826+. |
Is 850+ MGO Manuka Honey Worth the Investment?
The high price point of premium Manuka honey with an 850+ MGO rating is a direct reflection of its rarity and potent properties. The factors influencing its cost are:
- Rarity of High-Grade Nectar: The production of very high MGO honey requires nectar from specific, concentrated areas of Manuka bush, which are often in remote parts of New Zealand and Australia and only bloom for a short season.
- Time and Maturation: The honey needs time to mature and allow the DHA to naturally convert into MGO, which is a slow process that increases the honey's potency over time.
- Harvesting and Processing Costs: Obtaining honey from remote locations, often by helicopter, and carefully handling it to preserve its active compounds adds to the production costs.
- Extensive Testing: Authentic, high-grade honey undergoes rigorous and expensive independent third-party testing to certify its MGO levels and purity.
For those with specific therapeutic needs, such as intensive digestive support or wound care, the investment in a high-potency grade may be justified by the enhanced benefits. However, for general daily wellness, a lower MGO grade may be sufficient and more budget-friendly. Ultimately, the value depends on your intended use.
How to Choose an Authentic MGO Product
With the market for Manuka honey being highly competitive, it is crucial to ensure you are buying an authentic product. A study in New Zealand found that MGO can be artificially added, highlighting the importance of verification. Follow these guidelines to ensure you purchase a genuine, high-quality Manuka honey.
Tips for Buying Genuine Manuka Honey
- Check for an MGO or UMF Rating: Authentic Manuka honey will clearly display a certified MGO or UMF rating, never vague terms like 'bioactive' or 'active'.
- Ensure it's from a Reputable Origin: Genuine, high-quality Manuka honey comes from New Zealand or Australia. Check that the product specifies the country of origin.
- Look for Independent Certification: Many reputable brands provide traceability codes on their jars that allow you to view independent lab test results, confirming the MGO levels and authenticity.
- Read the Producer's Information: Trusted brands are transparent about their sourcing, testing, and production methods. A company that values quality and ethical practices will usually communicate this clearly.
- Consider the Monofloral/Multifloral Distinction: The New Zealand government regulates Manuka honey labels based on specific chemical markers and pollen content. 'Monofloral' typically indicates a higher concentration of Manuka-specific compounds and higher potency, while 'multifloral' suggests a lower concentration.
Conclusion
Understanding what 850+ MGO means is key to making an informed decision when purchasing Manuka honey. It signifies a premium, high-potency product with a minimum of 850mg of methylglyoxal per kilogram, reflecting its superior antibacterial and anti-inflammatory properties. While this high grade offers enhanced benefits for targeted therapeutic uses like immune and digestive support, lower MGO levels may suffice for daily wellness. For the highest assurance of quality and authenticity, consumers should seek third-party verification through MGO testing or the broader UMF certification system. By knowing what these ratings mean and how to spot a genuine product, you can effectively choose the Manuka honey that best fits your wellness goals. For more in-depth information, you can explore the resources available through trusted industry associations like the UMF Honey Association.
