Decoding the MGO Rating: The Power of Methylglyoxal
The MGO rating is a critical indicator of Manuka honey's potency. It measures the concentration of methylglyoxal (MGO), a naturally occurring antibacterial compound found in the honey. The number '100' on a Manuka honey jar indicates that the product contains a minimum of 100 milligrams of MGO per kilogram (mg/kg) of honey. This is considered an entry-level or milder strength, ideal for general daily use rather than for intensive therapeutic purposes. The presence of MGO is what sets Manuka honey apart from standard table honey, where the antibacterial activity is often derived from hydrogen peroxide, which is less stable.
The journey of MGO begins in the nectar of the Manuka bush (Leptospermum scoparium) native to New Zealand. The nectar contains a compound called dihydroxyacetone (DHA). After the bees collect the nectar and produce the honey, the DHA slowly converts into MGO during the honey's maturation and storage. This conversion process is why Manuka honey producers test for MGO levels, as the final potency depends on the original DHA content in the nectar and the subsequent aging process.
Benefits and Everyday Uses of MGO 100 Manuka Honey
While higher MGO ratings indicate greater potency, MGO 100+ honey offers a balanced and versatile option for many consumers. Its benefits are geared towards general wellness and can be easily incorporated into a daily routine.
- Daily Wellness: It serves as an excellent natural sweetener for tea, smoothies, and breakfast foods, offering a gentle immune boost.
- Sore Throat Relief: A spoonful can provide soothing relief for minor sore throats or coughs.
- Flavor Profile: With its lower MGO content, it tends to have a milder, less intense flavor, making it a delicious culinary honey.
- Digestive Health: It supports a healthy gut microbial balance due to its antibacterial and prebiotic potential.
- Topical Application: Although less potent than higher grades, it can still be used topically on minor cuts or blemishes for its antibacterial effects.
- Cost-Effective: MGO 100+ is typically more affordable than high-potency medical-grade Manuka honey, making it a budget-friendly option for those new to Manuka honey.
Understanding MGO vs. UMF: The Grading Difference
Another common rating system is UMF (Unique Manuka Factor), managed by the UMF Honey Association. While MGO focuses solely on the methylglyoxal content, UMF is a more comprehensive system that measures three key chemical markers: MGO, DHA, and Leptosperin, an indicator of authenticity. This broader testing ensures the honey is genuine, pure, and has a verifiable shelf life.
| Feature | MGO Rating | UMF Rating |
|---|---|---|
| Measurement | Measures only the Methylglyoxal (MGO) content in mg/kg. | Measures MGO, DHA, and Leptosperin, plus HMF for freshness. |
| Indicates | The antibacterial potency based on MGO levels. | A broader assurance of authenticity, potency, purity, and freshness. |
| Scope | A simpler, more straightforward system. | A comprehensive, advanced grading system verified by an independent association. |
| Equivalency | MGO 100+ has an approximate UMF rating of 5+ to 6+. | UMF 5+ correlates to roughly MGO 85+, while UMF 10+ is MGO 263+. |
| Authority | Used by many producers to highlight MGO potency. | A trademarked system with strict standards for licensing. |
How to Choose Your MGO Level
Choosing the right MGO strength depends on your specific needs and intended use. For everyday general wellness, like sweetening food or drinks, MGO 100+ is a perfect choice. It provides a reliable level of antibacterial activity without the high cost of a medical-grade product. If you are looking for more targeted therapeutic support, such as for digestive issues or skin problems, you may want to consider a higher MGO rating, such as MGO 300+ or MGO 550+. For the most potent effects, high-strength honey with MGO 850+ and above is available, often reserved for clinical applications.
Conclusion
An MGO 100+ rating on a jar of Manuka honey is a clear indicator of its methylglyoxal content, guaranteeing a minimum of 100mg of this potent antibacterial compound per kilogram. This level represents a valuable and accessible entry point into the world of Manuka honey, perfect for daily wellness, immune support, and culinary enjoyment. While it offers milder benefits compared to higher grades, its regular use can contribute positively to overall health. Consumers should consider their intended use and budget when selecting an MGO strength, and may also look for the comprehensive UMF certification for added assurance of authenticity and quality. Ultimately, understanding what MGO 100 means allows you to make an informed choice and harness the natural power of this unique New Zealand honey.
