Demystifying MGO: The Science Behind the Number
MGO stands for methylglyoxal, a naturally occurring organic compound found in high concentrations in genuine Manuka honey. It is derived from another compound, dihydroxyacetone (DHA), which is present in the nectar of the Manuka tea tree. As the honey matures, the DHA is converted into MGO, with the MGO level being scientifically tested and certified. This MGO content is what gives Manuka honey its potent antimicrobial and antibacterial properties, distinguishing it from other types of honey. Therefore, the number attached to the 'MGO' rating, such as MGO 200+, is a direct measurement of the potency of the honey.
What an MGO 200+ Rating Signifies
When a jar of Manuka honey is labeled MGO 200+, it means it contains at least 200 milligrams of methylglyoxal per kilogram of honey. This level is considered a moderate to high potency and is suitable for those seeking more than just a culinary sweetener. It represents a significant concentration of the bioactive compound, making it effective for general wellness and targeted applications. The '+' sign indicates that the honey contains this amount or more. For consumers, this rating is a crucial tool for verifying the product's authenticity and therapeutic potential.
The Health and Wellness Benefits of MGO 200+
The increased methylglyoxal content in MGO 200+ Manuka honey offers a range of health benefits that are more pronounced than in lower-rated varieties. Its strong antibacterial properties are a primary reason for its popularity, but its effects extend further. This level of honey is often sought for:
-
Immune support: During cold and flu season, an MGO 200+ honey can provide a powerful boost to the immune system.
-
Digestive health: Its antimicrobial qualities can help balance gut flora and soothe digestive discomfort.
-
Sore throats and oral health: The antibacterial action is effective at soothing sore throats and supporting overall oral hygiene.
-
Skin and topical applications: It can be applied topically to minor cuts, burns, and other skin irritations to assist with healing and ward off bacteria.
MGO vs. UMF: Understanding Different Grading Systems
While MGO is a widely used grading system, you may also see UMF (Unique Manuka Factor) on honey labels. UMF is a more comprehensive system that measures not only the MGO content but also other markers of Manuka authenticity, including Leptosperin and DHA. Both systems are valuable indicators of quality and potency, but they are measured differently. MGO specifically quantifies the methylglyoxal, making it a clear, direct metric, whereas UMF provides a broader assurance of the honey's overall activity level. Choosing between MGO and UMF often depends on consumer preference and the level of authentication desired.
| Feature | MGO Grading System | UMF Grading System |
|---|---|---|
| Measurement Focus | Quantifies methylglyoxal (MGO) content specifically. | Measures MGO along with other markers (Leptosperin, DHA) to determine the overall non-peroxide activity. |
| Scale | Direct mg/kg number (e.g., MGO 200+). | Broader rating based on UMF license (e.g., UMF™ 10+, UMF™ 15+). |
| Key Benefit | Simple, clear indication of antibacterial potency. | More comprehensive authenticity guarantee, as it measures multiple compounds. |
| Industry Recognition | Widely used and understood globally. | Trademarked and regulated by the UMF Honey Association. |
What to Look for When Buying MGO 200+ Manuka Honey
To ensure you are purchasing genuine Manuka honey with a certified MGO 200+ rating, always check for third-party testing information. Many reputable brands provide this information via a QR code or batch number on the label, which you can scan to view the honey's specific test results. This transparency is key to ensuring you are getting the potency and purity you expect. Also, be sure to purchase from a trusted source, as the market contains products with fraudulent or misleading labels. Genuine Manuka honey comes from New Zealand or parts of southeast Australia, so check the origin.
Conclusion
The 'MGO 200+' rating is much more than a number on a jar of Manuka honey. It is a certified measure of the honey's potency, specifically indicating a minimum of 200mg of the powerful antibacterial compound methylglyoxal per kilogram. For consumers, this level represents a versatile and effective grade for targeted wellness needs, from supporting immune health to aiding digestion and topical healing. By understanding what MGO means and how it compares to other grading systems like UMF, you can make an informed decision and choose the right Manuka honey for your specific health and wellness goals. Always verify authenticity by looking for transparent third-party testing to ensure you receive the high-quality product you expect.
