What is MGO and Why is it Important?
MGO, or Methylglyoxal, is a naturally occurring compound that is a key indicator of Manuka honey's potency. It is formed from Dihydroxyacetone (DHA), a compound present in the nectar of the New Zealand Manuka bush (Leptospermum scoparium). While most honeys have antibacterial properties due to hydrogen peroxide, Manuka's unique non-peroxide activity is attributed to its high and stable MGO levels. The number displayed on a jar of Manuka honey, such as 525+, indicates that there are at least 525 milligrams of MGO per kilogram of honey. The higher the MGO rating, the higher the concentration of this compound and the more potent the honey's antimicrobial effects.
The Power of 525 MGO Manuka Honey
A 525+ MGO rating places Manuka honey in the high-strength category, making it a powerful natural remedy. It is typically sought after for its therapeutic and medicinal properties rather than for everyday culinary use, for which lower MGO grades are more suitable. Consumers often turn to MGO 525+ for more robust and targeted health support, especially during the colder months or when a more concentrated antibacterial boost is desired.
Therapeutic and Wellness Benefits
- Immune System Support: The strong antibacterial and anti-inflammatory properties can provide extra immune support when your system needs it most.
- Digestive Health: MGO 525+ Manuka honey can help balance gut flora, soothe stomach irritation, and support overall digestive health.
- Throat and Oral Care: Its potent antimicrobial effects make it effective for soothing sore throats and combating harmful oral bacteria associated with plaque and gingivitis.
- Skin Care and Wound Healing: Medically-sterilised Manuka honey is used in clinical settings for wound healing, but high-strength consumer-grade honey can be used topically for minor skin irritations, acne, and to hydrate the skin.
Comparison of MGO Grades
To understand why MGO 525+ is considered a good choice, it helps to compare it with other common MGO grades. The following table provides a quick overview:
| MGO Grade | Potency Level | Typical Usage |
|---|---|---|
| MGO 40+ to 100+ | Mild | Everyday culinary use, general well-being. |
| MGO 250+ to 400+ | Moderate to High | Seasonal wellness, enhanced digestive support. |
| MGO 525+ | High Strength | Targeted immune and digestive support, extra potency. |
| MGO 850+ and above | Premium to Highest Strength | Intensive, specific, or therapeutic applications. |
How to Choose Authentic Manuka Honey
With the prevalence of counterfeit products, ensuring you buy genuine Manuka honey is crucial. Follow these guidelines to make an informed purchase:
- Check for Certified Ratings: Look for clear certification labels such as UMF™ or MGO™, which guarantee the honey has been tested by an independent laboratory. These ratings verify the presence and level of key compounds like MGO and Leptosperin.
- Verify Origin: Authentic Manuka honey comes from New Zealand. The label should explicitly state "Product of New Zealand," and many brands offer batch traceability via a QR code.
- Avoid Unofficial Terms: Be wary of vague marketing terms like "active," "bioactive," or high DHA levels without a verified MGO or UMF™ rating.
Conclusion: Is 525 MGO Manuka Honey Good?
Yes, 525 MGO Manuka honey is an excellent and potent choice for those seeking concentrated wellness benefits. Its high methylglyoxal concentration makes it suitable for targeted immune, digestive, and oral health support, surpassing the strength of lower-grade Manuka honeys. While it's not the highest grade available, MGO 525+ offers a significant step up from everyday varieties, providing robust therapeutic properties for specific health goals. When purchasing, always verify authenticity through MGO or UMF™ certification and its New Zealand origin to ensure you receive a high-quality product.

The Difference Between MGO, UMF™, and NPA
- MGO (Methylglyoxal): This is the direct, scientifically measured quantity of the antibacterial compound in the honey, expressed in mg/kg. It is considered the most reliable indicator of antibacterial potency.
- UMF™ (Unique Manuka Factor): This is a trademarked, comprehensive certification system that measures MGO, DHA, Leptosperin, and other markers to guarantee authenticity and purity. The UMF™ grade correlates directly with the MGO level.
- NPA (Non-Peroxide Activity): This refers to the non-hydrogen peroxide-related antibacterial activity in Manuka honey, which is primarily driven by MGO. The NPA rating is often similar to the UMF™ rating but is not a regulated certification in the same way.
Is Higher MGO Always Better?
While higher MGO ratings, such as 850+ or 1000+, indicate greater potency, they are also rarer and more expensive. A grade like MGO 525+ is often the ideal balance for consumers seeking robust benefits for a wide range of applications without paying the premium for the very highest concentrations. The best choice depends on your specific health goals and budget.
Is MGO 525+ Safe for Daily Consumption?
For most people, consuming small amounts of MGO 525+ daily is safe and can provide benefits. However, like all honey, it is high in sugar. Those with diabetes or individuals with specific health conditions should consult a healthcare professional before incorporating it regularly into their diet. It is not suitable for infants under 12 months due to the risk of botulism.
Why is Manuka Honey so Expensive?
The higher price of Manuka honey is due to several factors, including its limited geographical source (New Zealand), the short flowering season of the Manuka bush, the difficulty of harvest, and the rigorous testing and certification processes required to prove its potency and authenticity. High-grade varieties like 525+ are rarer, which further increases the cost.
Uses of 525 MGO Manuka Honey
- Internal Wellness: Take a teaspoon daily for immune and digestive support. It can be consumed straight, mixed with warm (not boiling) water, or added to smoothies.
- External Applications: Apply a thin layer to minor skin irritations or acne spots. A patch test is recommended first.
- Culinary Enhancer: Use it as a natural sweetener in teas or drizzled over toast and yogurt for a potent, earthy flavor, though its therapeutic value makes it more valuable for health applications.
Who Should Not Use MGO 525+ Manuka Honey?
Individuals allergic to honey or bees should avoid Manuka honey. It is also not recommended for infants under one year old due to the risk of infant botulism. People with diabetes or those on chemotherapy should consult a doctor before use due to potential effects on blood sugar and interactions.
