What Exactly is MGO in Manuka Honey?
Methylglyoxal (MGO) is a naturally occurring organic compound that is a key bioactive marker in Manuka honey, setting it apart from other types of honey. Unlike the antibacterial effect of regular honey, which is primarily due to hydrogen peroxide and can be unstable, MGO's potent antibacterial properties are resistant to heat and other environmental factors. The MGO level is measured in milligrams per kilogram (mg/kg) of honey, and this number is prominently displayed on authentic Manuka honey products. The higher the number, the more potent the honey's antibacterial activity. The MGO content develops over time from another compound, dihydroxyacetone (DHA), which is found in the nectar of the Manuka flower. This means that the beekeeper and producer must take great care to mature and test the honey to ensure its potency.
High MGO Honey for Wound Care and Skin Health
One of the most well-documented uses of high MGO honey is for wound healing and overall skin health. Research shows that its high MGO content gives it powerful antibacterial and antimicrobial properties that are effective against a wide range of bacteria, including antibiotic-resistant strains like MRSA.
- Promotes Faster Healing: High MGO honey can stimulate tissue regeneration, accelerate the removal of dead tissue (debridement), and create a protective barrier on the skin. Its anti-inflammatory action also reduces swelling and pain.
- Fights Acne: For topical use, the antibacterial and anti-inflammatory properties of high MGO honey make it an effective treatment for acne. It can be used as a spot treatment or face mask to combat acne-causing bacteria and reduce inflammation.
- Soothes Skin Conditions: It can be beneficial for other skin ailments like eczema and dermatitis by soothing irritated skin and reducing redness.
Digestive and Gut Health Support
Beyond topical applications, ingesting high MGO Manuka honey can provide significant benefits for digestive health. It acts as a natural ally for a healthy gut microbiome.
- Fights Harmful Bacteria: The strong antibacterial properties of MGO are effective against harmful bacteria in the gut, such as H. pylori, which is linked to stomach ulcers and gastritis.
- Supports Beneficial Bacteria: Manuka honey contains natural prebiotics that help promote the growth of good gut bacteria.
- Soothes Inflammation: Its anti-inflammatory effects can help soothe the gut lining and alleviate symptoms of digestive discomfort like bloating, indigestion, and acid reflux.
- Healing Ulcers: The high MGO concentration can create a protective barrier in the digestive tract, which helps in the healing of stomach ulcers.
Relief for Sore Throats and Colds
High MGO honey is a popular natural remedy for soothing sore throats and calming coughs, particularly during cold and flu season. Its viscous nature creates a soothing coating on the throat, providing immediate relief from irritation. The potent MGO actively works to combat the bacteria that may be causing the infection or inflammation, offering therapeutic benefits beyond just providing comfort. Its anti-inflammatory properties further help reduce swelling and irritation in the throat.
Immune System Support
Regular consumption of high MGO honey can provide general immune support. Its antioxidant, antibacterial, and anti-inflammatory properties help fortify the body's natural defenses and combat oxidative stress. While not a replacement for medical treatment, incorporating high-potency Manuka honey into your diet can be a proactive step toward maintaining overall wellness.
Comparison of MGO Honey Potency and Uses
To help you decide which MGO level is right for your needs, here is a comparison of typical MGO ratings and their common uses. The higher the number, the greater the potency.
| MGO Grade | Potency Level | Typical Usage & Benefits |
|---|---|---|
| MGO 100+ to 250+ | General Wellness | Daily use for immune maintenance, a natural alternative sweetener, and supporting overall wellbeing. |
| MGO 260+ to 500+ | Medicinal Strength | Moderate antibacterial support, ideal for soothing sore throats, minor cuts, scrapes, and burns, and maintaining digestive health. |

| MGO 1000+ and Above | Superior/Ultimate Strength | Reserved for intensive therapeutic use, such as severe or chronic health concerns including complex gut health issues and difficult-to-heal wounds. |
The Importance of Purity and Authenticity
When purchasing high MGO honey, particularly Manuka honey, it is critical to ensure its authenticity. Genuine Manuka honey is produced in Australia and New Zealand, and reputable producers will have their honey independently tested and certified for its MGO content. Always look for certification on the label to guarantee you are purchasing a product with the stated level of potency. Some brands also provide full traceability, allowing you to trace your jar back to its source. Choosing certified, high-grade honey ensures you are receiving the maximum benefits of its therapeutic properties.
Conclusion
High MGO honey, primarily Manuka honey, is a powerful natural remedy with scientifically backed antibacterial, anti-inflammatory, and antioxidant properties. Its numerous benefits make it a versatile tool for supporting overall health, from accelerating wound healing and soothing sore throats to promoting robust digestive and skin health. While lower MGO grades are suitable for general wellness, higher potency honey is sought after for more targeted and therapeutic applications. By understanding the MGO rating system and prioritizing authentic, certified products, consumers can effectively harness the powerful healing properties of this remarkable superfood. Always consult a healthcare professional for persistent or serious health concerns. For further reading on the science behind MGO, explore resources like the National Institutes of Health.
