What is a good MGO rating for Manuka honey?

Manuka honey contains a naturally occurring compound called methylglyoxal (MGO), which is responsible for its unique antibacterial properties. Knowing what is a good MGO rating depends entirely on your intended use, from a simple daily supplement to a potent medicinal application.

Quick Summary

Understanding Manuka honey MGO ratings is key to selecting the right product. The higher the MGO number, the stronger the antibacterial activity, with different potencies suitable for various health and wellness applications.

Key Points

• MGO Explained: MGO (Methylglyoxal) is the primary compound responsible for Manuka honey's antibacterial properties, with the rating indicating its concentration in mg/kg.

• Low MGO (40+ to 250+): Ideal for general wellbeing, daily use as a natural sweetener, and for its milder taste.

• High MGO (500+ and above): Provides superior potency for targeted therapeutic uses, such as intensive wound care, digestive issues, and immune support.

• MGO vs. UMF: MGO measures a single compound, while UMF is a comprehensive certification that also checks for other authenticity markers like DHA and Leptosperin.

• Choosing the Right Level: The best MGO rating depends on your specific health goals, budget, and taste preference, not simply selecting the highest number.

• Verify Authenticity: Always check for transparent labeling, batch codes, and third-party certifications (like UMF) to ensure you are buying genuine Manuka honey.

Understanding Manuka Honey MGO Ratings

MGO stands for methylglyoxal, a compound naturally produced in Manuka honey that gives it its potent antibacterial qualities. This substance forms during the honey's maturation process from a precursor compound called dihydroxyacetone (DHA), which is found in the nectar of the Manuka tea tree. The MGO number on a honey jar indicates the concentration of methylglyoxal in milligrams per kilogram (mg/kg). For example, a honey with an MGO 400+ rating has at least 400 mg of MGO per kilogram of honey. This provides a direct and straightforward way to measure the honey's potency.

The MGO rating system is a globally recognized and scientifically backed standard for grading Manuka honey, but it is important to remember that a 'good' rating is relative to your needs. A higher number does not automatically mean it is the best choice for every consumer. The ideal rating depends on the intended application, desired intensity of benefit, and budget. Lower grades are excellent for everyday consumption, while higher grades are reserved for more intensive therapeutic uses.

Decoding the Different MGO Strength Levels

Manuka honey is typically available in a range of MGO strengths, catering to different purposes. The following breakdown can help you decide which potency is right for you:

• Everyday Wellness (MGO 40+ to MGO 250+): Honeys in this range have mild to moderate antibacterial activity and are ideal for general health maintenance and daily use. They make a perfect natural sweetener for tea, toast, or breakfast foods and can support overall wellbeing. The taste is typically sweeter and less intense than higher-rated varieties.

• Targeted Support (MGO 260+ to MGO 500+): This is the entry-level for medicinal use, offering a more pronounced antibacterial effect. It is a popular choice during cold and flu season to provide extra immune support or for soothing sore throats. It can also be used topically for minor cuts, scrapes, and bruises.

• Therapeutic and High Potency (MGO 500+ to MGO 1000+): Honeys in this category are considered high-strength and are often recommended for more specific health concerns. They offer superior potency for maintaining digestive health, supporting the healing of skin ailments like eczema or acne, and assisting with wound care. The flavor is noticeably more robust and earthy.

• Superior Strength (MGO 1000+ and above): These are the rarest and most potent Manuka honeys, with significant therapeutic benefits. They are typically used for more severe or chronic issues, such as bacterial infections, ulcers, and serious burns. Due to their rarity and potency, these honeys command a premium price.

MGO vs. UMF: Understanding the Rating Systems

While MGO is a direct measurement of one key compound, the UMF (Unique Manuka Factor) is another common grading system that offers a more comprehensive quality assessment.

What is UMF?

The Unique Manuka Factor Association (UMFHA) oversees the UMF certification, which tests for four key markers to verify a product's authenticity, purity, freshness, and potency:

• MGO: The level of methylglyoxal.
• DHA: The level of dihydroxyacetone, the precursor to MGO, which indicates the honey's shelf life.
• Leptosperin: A unique compound found only in Manuka nectar that proves authenticity.
• HMF: A freshness indicator (Hydroxymethylfurfural).

UMF ratings, like MGO ratings, correspond to different levels of potency. For example, a UMF 10+ honey has an MGO equivalent of at least 263+. For consumers who prioritize authenticity and transparency, looking for both a UMF and an MGO rating on a jar is a reliable strategy. However, many high-quality honeys are sold with just an MGO rating, as it is a more straightforward metric to understand.

MGO vs. UMF Comparison Table

Feature	MGO Rating	UMF Rating
Measurement Focus	Measures the concentration of methylglyoxal (mg/kg) only.	Measures MGO plus other key markers (DHA, Leptosperin, HMF).
Certification	Often certified by the manufacturer or independent lab testing.	Independently verified and licensed by the UMF Honey Association.
Simplicity	Provides a single, clear number for potency.	Offers a more complete picture of quality and authenticity.
Range	Can range from low double digits to over 1000+.	Typically ranges from 5+ to 25+.
Authenticity Check	Requires checking for third-party lab reports or batch codes.	Confirms authenticity and freshness through the UMF trademark.

Factors Influencing MGO Levels

Several factors can cause MGO levels to vary significantly between batches of Manuka honey:

• Geographical Location: The specific location where the bees forage can impact the quality of the nectar.
• Climatic Conditions: Weather patterns during the Manuka flowering season can affect the nectar's DHA content.
• Beekeeping Practices: The skill of the beekeeper and the hive's management can influence the honey's final composition.
• Aging Process: MGO levels naturally increase as the honey matures over time, with DHA converting to MGO during storage.

Conclusion: Choosing the Right MGO for You

In conclusion, there is no single best MGO rating for Manuka honey; the optimal level depends entirely on your needs. For everyday wellness and general maintenance, a lower MGO rating (40+ to 250+) provides a great natural treat with mild health benefits. For targeted support, such as boosting immunity during seasonal changes, a moderate rating (260+ to 500+) is more appropriate. Finally, for therapeutic applications like wound care or serious digestive issues, a high-potency honey (500+ and above) is most effective due to its powerful antibacterial properties. When making your choice, consider your health goals, preferred taste, and budget. Always look for transparent labeling, and if in doubt, opt for products with UMF certification for added assurance of authenticity and quality.
