Understanding Manuka Honey Grades: MGO vs. UMF
Before you can decide which Manuka honey is best for eating, it's crucial to understand the grading systems that determine its quality and potency. The two most common and reputable systems are MGO and UMF.
MGO (Methylglyoxal) Grading
MGO stands for methylglyoxal, a naturally occurring compound found in Manuka honey that gives it its potent antibacterial properties. The MGO rating indicates the concentration of this compound in milligrams per kilogram (mg/kg). The higher the number, the higher the concentration and potency. An MGO 250+ honey, for example, contains at least 250mg of methylglyoxal per kg of honey. MGO can also be synthetically added, so it does not guarantee authenticity alone.
UMF (Unique Manuka Factor) Grading
UMF is a more comprehensive and trusted grading system, developed by the UMF Honey Association. Unlike MGO, UMF tests for multiple unique signature compounds to ensure authenticity, purity, and potency. These compounds include Methylglyoxal (MGO), Leptosperin (an authenticity marker), Dihydroxyacetone (DHA), and Hydroxymethylfurfural (HMF). A higher UMF rating signifies a more potent and pure product. While MGO measures a single chemical, UMF provides a holistic assurance of quality and origin.
Which Manuka Honey Grade is Right for You?
Your choice of Manuka honey should align with your intended use. Lower grades are perfect for everyday eating and cooking, while higher grades are better for targeted wellness benefits.
Manuka Honey for Culinary Use
If you simply want to enjoy the rich, earthy flavor of Manuka honey as a natural sweetener, lower MGO and UMF grades are the best value. These honeys have a mild, sweet taste perfect for everyday consumption.
- Recommended Grades: MGO 40+ to 100+ or UMF 5+ to 10+.
- Best For: Adding to tea or smoothies, drizzling over oatmeal or yogurt, and using in dressings or glazes.
Manuka Honey for Daily Wellness
For those seeking moderate immune support or general well-being, a mid-range Manuka honey is a great choice. These grades offer more antibacterial activity than table-grade honey without the high price tag of therapeutic grades.
- Recommended Grades: MGO 250+ to 400+ or UMF 10+ to 15+.
- Best For: Taking a daily spoonful to boost immunity or support gut health.
Manuka Honey for Targeted Health Benefits
When you need potent antibacterial or anti-inflammatory support for more specific health issues, a higher-grade Manuka honey is more effective. These grades are significantly more potent and carry a more intense, sometimes described as 'medicinal', flavor.
- Recommended Grades: MGO 500+ and higher or UMF 15+ and higher.
- Best For: Soothing sore throats, coughs, and supporting digestive health during illness.

Practical Tips for Eating Manuka Honey
Incorporating Manuka honey into your diet is easy and delicious. Here are a few ways to make the most of your honey, based on its grade:
- Add to warm (not hot) drinks: High temperatures can break down the beneficial enzymes. For a sore throat, mix it into warm tea with lemon and ginger.
- Drizzle over breakfast: A spoonful of lower-grade Manuka over yogurt, oatmeal, or muesli is a fantastic way to start the day.
- Use in marinades and dressings: The rich flavor of Manuka can add a unique twist to savory dishes like honey-glazed salmon or salad dressings. Lower grades are suitable for this purpose. If cooking, remember to reduce the oven temperature by about 10°C as honey burns faster than sugar.
- Take a spoonful directly: For targeted wellness benefits from a high-grade honey, simply take a spoonful straight from the jar, allowing it to coat your throat and be absorbed by the body.
Precautions and Sourcing
While Manuka honey is generally safe for most people, certain precautions are important. Due to its high sugar content, individuals with diabetes should consult a doctor before incorporating it into their regimen. It should also not be given to children under 12 months old due to the risk of botulism. Always purchase from a reputable brand to ensure authenticity, and look for jars certified by the UMF Honey Association.

Conclusion
Choosing the best Manuka honey for eating ultimately depends on your purpose and budget. For culinary applications and daily sweetening, a lower MGO (40+ to 100+) or UMF (5+ to 10+) grade provides a delicious and affordable option. For those focused on a daily wellness boost, a mid-range grade (e.g., MGO 250+, UMF 10+) is a great compromise. If your goal is targeted therapeutic support for specific health concerns, investing in a higher-grade Manuka (MGO 500+, UMF 15+) ensures maximum potency. By understanding the grading systems and aligning your choice with your needs, you can confidently select the perfect Manuka honey for eating, enjoying its unique flavor and potential benefits.
