Understanding the MGO Rating System
Manuka honey, primarily sourced from New Zealand and Australia, contains a unique compound called methylglyoxal (MGO) that gives it potent antibacterial properties. While all honey possesses some antimicrobial activity, the high concentration of MGO in Manuka honey sets it apart. The MGO rating on a jar indicates the concentration of methylglyoxal in milligrams per kilogram (mg/kg). A higher MGO number signifies a more potent product. For instance, an MGO 400+ honey contains at least 400 mg of MGO per kg.
Unlike other honey varieties, which rely on hydrogen peroxide for much of their antibacterial effect, Manuka's activity is primarily non-peroxide based, making it more stable and effective against a wider range of bacteria. This is why the MGO rating is the most reliable measure of its medicinal strength.
Choosing MGO Potency for Your Needs
Selecting the correct MGO strength is crucial for maximizing benefits. It's not always necessary to buy the highest grade available, as different MGO levels are best suited for different applications.
Low MGO (Upto 250+): Daily Wellness
Products with lower MGO ratings are excellent for general daily use and maintenance of overall well-being. They provide a milder antibacterial and prebiotic effect, making them a great addition to your diet.
- Daily support: Adding to food or drink can support the immune system.
- Soothing sore throats: Its anti-inflammatory and antibacterial properties can offer relief for mild throat irritation.
- Digestive health: Regular consumption can aid in maintaining a healthy gut microbiome by acting as a prebiotic.
Medium MGO (250+ to 500+): Digestive and Skin Support
Mid-range MGO Manuka honey is a versatile choice for those with more specific health concerns. This strength is sufficient for targeting mild to moderate issues while remaining suitable for daily intake.
- Targeted gut issues: Research indicates Manuka honey can be effective against harmful bacteria like H. pylori, which causes stomach ulcers.
- Skin conditions: Applying topically can help soothe and heal skin issues like acne, eczema, and minor cuts due to its anti-inflammatory and antibacterial effects.
- Upper respiratory infections: May be more effective for calming persistent coughs and relieving congestion associated with infections.
High MGO (500+ and Above): Targeted Therapeutic Uses
The most potent Manuka honey varieties are reserved for serious and targeted therapeutic applications. These are typically used for more severe or persistent issues where maximum antibacterial activity is required.
- Wound healing: Medical-grade Manuka honey (often MGO 500+ and higher) is used clinically for treating burns, chronic wounds, and ulcers.
- Combating persistent bacteria: High-strength Manuka has been studied for its effectiveness against resistant bacteria, including MRSA and Clostridium difficile.
- Severe skin ailments: Can be used as a topical treatment for stubborn skin infections and to accelerate tissue repair.
Factors Beyond MGO: A Comprehensive Buying Checklist
While MGO is a key indicator of potency, it's not the only factor to consider. Use this checklist to ensure you are purchasing a genuine and high-quality product:
- Origin: Always verify that the honey is from New Zealand or Australia, the only places where genuine Manuka honey is produced.
- UMF Certification: Look for the Unique Manuka Factor (UMF) trademark on the label. This independent certification tests not only for MGO but also for other markers like Leptosperin and DHA, ensuring purity and authenticity. UMF and MGO have a direct correlation. For example, UMF 10+ is roughly equivalent to MGO 263+, UMF 15+ to MGO 514+, and UMF 20+ to MGO 829+.
- Traceability: Reputable brands often provide a batch number on the jar, allowing you to trace the honey back to its origin and view test results.
- Raw vs. Processed: For maximum health benefits, choose raw Manuka honey. Raw honey is unpasteurized and unprocessed, retaining more of its natural enzymes and antioxidants.
- Brand Reputation: Stick to well-known, certified brands. The market is saturated with counterfeit Manuka honey products.
MGO Comparison Table
| MGO Rating | Suggested Use | Price Range |
|---|---|---|
| 80+ to 250+ | General wellness, daily consumption, mild throat soothing | Lower |
| 250+ to 500+ | Targeted digestive support, stomach ulcers, skin care (acne) | Mid-range |
| 500+ and above | Therapeutic wound care, severe skin infections, persistent bacteria | Higher |
Avoiding Fake Manuka Honey
The high demand for Manuka honey has led to many counterfeit products on the market. To avoid being scammed, always follow these tips:
- Check the Label: Look for the MGO and/or UMF rating clearly displayed. Avoid generic labels like 'Manuka blend'.
- Read the Certifications: Ensure the product is certified by a recognized authority like the UMF Honey Association. Authentic products will have a seal and a unique license number.
- Know the Source: Only purchase from trusted brands that can prove the honey's origin and batch testing.
- Check Price: High-grade Manuka honey is expensive to produce. If the price seems too good to be true, it probably is.
Conclusion: Making Your Informed Choice
Deciding which MGO Manuka honey to buy comes down to your intended use and budget. For general daily health, a lower MGO rating is perfectly sufficient and more affordable. If you are looking for support for specific digestive issues or skin ailments, a medium-strength MGO offers a great balance of potency and value. For serious, targeted therapeutic applications like wound care, investing in a high MGO product is essential for maximum antibacterial effect. By understanding the MGO system and looking for proper certifications, you can confidently choose the right Manuka honey to support your health and wellness goals.

How to Use Manuka Honey
- Oral Consumption for Digestion: For issues like stomach ulcers or general gut health, it can be consumed directly.
- Oral Consumption for Soothing: Stir into warm (not hot) water or tea to preserve its enzymes. Add to smoothies, oatmeal, or yogurt.
- Topical Application for Skin: For conditions like acne or eczema, apply a thin layer directly to the affected area. Leave for a period before rinsing off with warm water.
- Topical Application for Wounds: For minor cuts and burns, apply a layer to the wound and cover with a sterile bandage. Change the dressing as needed.
Consistency is key for observing the health benefits, especially for internal applications.
