The Difference Between MGO and UMF
The labels on Manuka honey jars can be confusing, with different grading systems like MGO and UMF displayed prominently. Understanding the fundamental difference between them is the first step toward making an informed purchase. Methylglyoxal (MGO) is a naturally occurring compound in Manuka honey that is responsible for its potent antibacterial properties. The MGO rating simply measures the concentration of this single compound in milligrams per kilogram (mg/kg).
In contrast, the Unique Manuka Factor (UMF) is a more comprehensive quality assurance system managed by the Unique Manuka Factor Honey Association (UMFHA). To receive a UMF rating, the honey must be independently tested for four key markers: MGO (for potency), Leptosperin (for authenticity, as it's unique to Manuka nectar), Dihydroxyacetone or DHA (for shelf life, as it converts to MGO over time), and Hydroxymethylfurfural or HMF (for freshness). This multi-compound approach provides a more robust guarantee of the honey's authenticity, purity, and longevity, in addition to its potency.
MGO 400+ to UMF 13+ Equivalence
The direct translation for Manuka honey with an MGO 400+ rating is a UMF 13+ certification. While the exact number can vary slightly between brands due to independent testing, this provides a clear benchmark for consumers. An MGO 400+ indicates a high level of methylglyoxal, making it a powerful honey with significant antibacterial activity suitable for both internal wellness and external applications. For therapeutic purposes, a UMF rating of 10+ or higher is generally considered beneficial, placing a UMF 13+ well within the therapeutic grade.
Benefits and Uses of MGO 400 / UMF 13+ Manuka Honey
An MGO 400+ / UMF 13+ Manuka honey offers a variety of health benefits due to its strong antibacterial and anti-inflammatory properties. This mid-to-high-grade honey is a popular choice for those seeking noticeable therapeutic effects. Some common uses and benefits include:
- Immune System Support: The high MGO concentration helps to fight infections and strengthen the body's natural defenses, especially during cold and flu season.
- Digestive Health: It can help soothe the digestive tract and is believed to support a healthy gut microbiome.
- Skincare and Wound Healing: When applied topically, it can help treat minor wounds, cuts, burns, and skin conditions like acne due to its powerful antibacterial action.
- Sore Throat and Oral Health: A spoonful can soothe a sore throat, and its antibacterial properties can also contribute to overall oral hygiene.
Choosing Between MGO and UMF Ratings
For consumers, the choice between MGO and UMF depends on what they value most. The MGO system offers a simple, direct measurement of one specific compound related to potency. The UMF system, however, provides a more holistic guarantee of authenticity and quality through multiple marker tests.
| Feature | MGO (Methylglyoxal) | UMF (Unique Manuka Factor) |
|---|---|---|
| Measurement | Measures only the Methylglyoxal (MGO) content. | Measures four compounds: MGO, Leptosperin, DHA, and HMF. |
| Scope | Simple, single-factor measurement of antibacterial potency. | Comprehensive quality and authenticity certification. |
| Authenticity | Does not guarantee authenticity or origin by itself. | Guarantees authentic, New Zealand origin Manuka honey through independent testing. |
| Traceability | Traceability depends on the brand's own practices. | Certified products are traceable back to the source. |
| Reliability | Reliable for measuring MGO potency, but can be susceptible to mislabeling. | Considered the 'gold standard' for quality assurance and authenticity. |
Conclusion: MGO 400 to UMF 13+ and Beyond
Understanding the distinction and equivalence between MGO and UMF is essential for any Manuka honey buyer. An MGO 400+ rating is a significant indicator of potency, and it directly corresponds to a UMF 13+ certification. While MGO provides a clear, quantitative measure of the honey's antibacterial strength, the UMF certification offers a broader guarantee of the product's overall authenticity, purity, and quality. Ultimately, choosing a honey with a certified UMF rating, such as UMF 13+, provides the highest level of assurance that you are receiving a genuine and potent Manuka honey product from New Zealand. This certification gives peace of mind that the investment in your health is well-placed, and you are getting the full, unique benefits this exceptional honey has to offer.

Frequently Asked Questions
How does MGO convert to UMF?
There is no direct mathematical conversion formula from MGO to UMF, but there is an established equivalence based on laboratory testing. For example, a honey with at least MGO 400 mg/kg is generally certified as UMF 13+. The UMF rating reflects a comprehensive analysis of multiple markers, not just MGO.
Is MGO 400 Manuka honey good?
Yes, MGO 400+ Manuka honey is considered a high-potency grade with significant antibacterial properties. It is a popular choice for supporting general wellness, boosting immunity, and for topical use on skin issues and minor wounds.
What does UMF stand for?
UMF stands for "Unique Manuka Factor," a quality trademark and grading system used to authenticate genuine Manuka honey from New Zealand. It measures a range of compounds, including MGO, Leptosperin, and DHA, to ensure potency, authenticity, and freshness.
How is UMF better than MGO?
UMF is considered a more comprehensive quality certification than MGO alone because it measures four distinct compounds and guarantees the honey's New Zealand origin. While MGO measures only one antibacterial marker, UMF tests verify authenticity and shelf life in addition to potency.
Can I use MGO 400+ for a sore throat?
Yes, Manuka honey with an MGO 400+ rating is known for its ability to soothe sore throats and provide antibacterial benefits that may help fight off infections causing the irritation. It can be taken by the spoonful or dissolved in warm water.
What are the main compounds measured by UMF?
The UMF certification measures four signature compounds: Methylglyoxal (MGO) for potency, Leptosperin for authenticity, Dihydroxyacetone (DHA) for shelf life, and Hydroxymethylfurfural (HMF) to ensure freshness and prevent overheating.
Is MGO 400+ considered therapeutic grade?
An MGO 400+ honey, which corresponds to UMF 13+, is considered within the therapeutic-grade range for Manuka honey. This grade offers a higher level of beneficial compounds compared to daily-use honey and is suitable for more targeted health applications.
