Manuka Honey MGO

What Does Manuka’s MGO Mean?

MGO in manuka honey is short for “methylglyoxal,” a compound naturally found in Manuka honey and the primary element responsible for this honey’s unique antibacterial properties. This compound forms in the honey over time through a natural process where DHA (dihydroxyacetone), found in the nectar of Manuka flowers, gradually converts into MGO. This conversion process is key to why Manuka honey is highly regarded for health purposes, especially compared to standard honey varieties, which generally lack this high MGO concentration.

The presence of MGO is what gives Manuka honey its recognised health benefits, from supporting wound healing to general immunity health. Scientific studies show that MGO in Manuka honey exhibits significant antibacterial effects, effectively inhibiting bacteria like Staphylococcus aureus and Escherichia coli . Research from the Institute of Food Chemistry at the Technische Universität Dresden, for instance, confirmed a direct correlation between MGO concentration and antibacterial activity. This means that higher MGO levels equate to more potent antibacterial properties, a characteristic unique to Manuka honey.

In fact, studies indicate that MGO levels of approximately 150 mg/kg and above are sufficient to give Manuka honey its notable antibacterial effects, even against resilient bacteria. While most other honeys contain some antibacterial content due to natural hydrogen peroxide, MGO sets Manuka apart offering higher, longer-lasting levels of potency. This potent activity is the result of a unique chemical reaction occurring in the New Zealand-based Manuka plant, giving its honey a recognised edge in natural health solutions.

MGO in Manuka Honey Production Quality

Manuka honey’s quality is often directly related to its MGO content, as this compound indicates the honey’s potency and purity. The concentration of MGO depends on various factors, including the honey’s processing, storage, and, most importantly, the natural growth conditions of the Manuka plant itself in New Zealand. During production, it’s crucial that Manuka honey is carefully handled to retain its MGO levels, as this is what sets it apart from other types of honey.

MGO levels in Manuka honey generally range from around 100 mg/kg in milder products to over 800 mg/kg in higher-grade varieties. Studies indicate that the antibacterial strength of Manuka honey becomes notably effective at levels around 150 mg/kg and above, with higher concentrations providing increased bioactivity. This means that while even lower MGO honey offers health benefits, higher MGO levels are more often favoured for targeted health applications, such as soothing sore throats, managing skin conditions, or supporting wound care.

In recent years, as awareness of Manuka honey’s benefits has grown, quality testing has become more rigorous to ensure the authenticity of MGO levels. For instance, the honey can both be tested for its MGO concentration as well as other purity markers to ensure consumers receive a genuine product with all the associated health benefits. Additionally, research highlights that this non-peroxide antibacterial property found in Manuka, attributed to MGO, remains stable under various conditions, allowing Manuka honey to be a versatile natural remedy.

What is MGO Manuka Honey Good For?

MGO in Manuka honey is celebrated not only for its distinctive taste but also for the potential health benefits associated with its high methylglyoxal content. MGO acts as a natural antibacterial and anti-inflammatory agent, giving Manuka honey unique health properties that go beyond what’s typically seen in other types of honey. Here are some of the main ways people use high-MGO Manuka honey to support their health:

Wound Care and Skin Health

One of the most recognised uses for high-MGO Manuka honey is in wound healing and skin care. Research shows that manuka honey can help combat bacteria that might otherwise cause infection, supporting a clean, balanced environment for wound recovery . Manuka honey is even applied in some clinical settings for its antibacterial effects, particularly for wounds that are slow to heal, such as diabetic ulcers. It’s also a popular natural option for skin conditions, like acne or eczema, as the honey’s antibacterial and anti-inflammatory properties may help reduce irritation and redness when applied topically .

Soothing Sore Throats and Coughs

Manuka honey, particularly high-MGO varieties, is often used as a natural remedy for sore throats and coughs. MGO works by combating harmful bacteria in the throat, providing relief and reducing irritation. Studies support MGO’s effectiveness in this regard, and many people report feeling relief when taking a spoonful of high-MGO Manuka honey during seasonal illnesses.

Supporting Digestive Health

Another common use for MGO Manuka honey is in digestive health. Some studies have suggested that MGO’s antibacterial effects may help balance gut bacteria and ease digestive discomfort, supporting a healthy microbiome . This makes Manuka honey a popular choice for individuals with digestive issues, including those looking to maintain balanced gut health naturally.

Immune Support

The antibacterial and anti-inflammatory properties of MGO provide overall immune support, helping the body resist infections. This is one of the reasons why high-MGO Manuka honey is often used during times when immune support is needed most, such as during seasonal changes or colder months.

Mouth and Stomach Ulcers

Manuka honey’s antibacterial strength, due to its high MGO levels, has shown promising benefits in supporting digestive health and managing conditions like mouth and stomach ulcers and GERD (Gastro Esophageal reflux disease). Research reveals that Manuka honey can inhibit Helicobacter pylori ( H. pylori ) , a common bacterium linked to stomach ulcers. In a 1994 study, researchers found that Manuka honey with sufficient MGO levels could inhibit the growth of H. pylori , thus creating an environment less conducive to ulcer formation and providing potential relief for people with stomach ulcers. Additionally, MGO in Manuka honey helps protect the stomach lining by reducing urease, an enzyme produced by H. pylori that irritates the stomach lining, making it a useful natural support for digestive health.

Cancer / Breast Cancer

Emerging research suggests that Manuka honey may play a supportive role in cancer treatment by enhancing the effects of conventional therapies. Some studies indicate that Manuka honey’s antioxidant and anti-inflammatory properties help inhibit the growth of cancer cells and improve the efficacy of chemotherapy. MGO and other bioactive compounds in Manuka honey are shown to reduce inflammation and oxidative stress, which can support the body’s resilience during cancer treatments. While more research is needed, these preliminary findings highlight the potential benefits of high-MGO Manuka honey in integrative oncology care.

From skincare to immune support, the range of uses for MGO-rich Manuka honey reflects its versatility as a natural remedy. With ongoing research, scientists are continuing to understand more about how this powerful compound benefits various aspects of health.

MGO Manuka Honey Rating

Which MGO Manuka Honey is Best?

Choosing the “best” MGO Manuka honey depends largely on what you intend to use it for, as different MGO levels provide varying intensities of antibacterial activity. To make this decision easier, MGO levels can be roughly divided into categories based on their primary uses:

1. Everyday Wellness and General Use (MGO 83–261)
   For daily health maintenance, such as adding honey to your diet for general wellness, a low to moderate MGO range is ideal. Manuka honey with MGO levels of 83 to 261 provides a good balance of flavour and mild antibacterial properties, supporting immune function and digestion. This range is perfect for people who want to incorporate a healthy honey option into their diet without the intense potency or premium price associated with higher MGO levels.
2. Targeted Health Support (MGO 261–512)
   When looking for Manuka honey with added strength for targeted health uses—such as soothing sore throats, supporting respiratory health, or using in skincare—opt for an MGO range between 261 and 512 . Studies show that honey in this range has a higher concentration of methylglyoxal, which is particularly effective against bacteria that cause throat irritation or minor skin blemishes. For those needing a natural remedy for seasonal wellness or minor skin concerns, this MGO range offers an ideal balance between potency and usability.
3. High Potency Care (MGO 512 and above)
   For those who require maximum antibacterial support—such as for wound care, immune support during illness, or managing skin conditions — a high MGO level (512 or more) is best . Manuka honey in this range is known for its intense antibacterial properties, making it particularly effective for targeted therapeutic applications. Clinical studies confirm that methylglyoxal at these levels can inhibit or kill certain bacteria that are often resistant to antibiotics, making it a valuable tool for those seeking natural remedies with powerful effects, complementing traditional antibiotics.

Ultimately, the “best” MGO level comes down to the intended application. For general wellness and culinary use, a low to mid-range MGO Manuka honey is sufficient. For therapeutic purposes, particularly those requiring antibacterial strength, high-MGO Manuka honey is ideal, providing the most potent benefits. However, in every case the higher the MGO level, the stronger its antimocrobial healing properties.

Manuka Honey MGO vs UMF

When evaluating Manuka honey, it’s common to see both MGO and UMF (Unique Manuka Factor) ratings on product labels. While both ratings indicate the honey’s quality, they measure different factors and provide distinct insights, while also using a different numbering system to add to the confusion. Here’s a breakdown of what each represents and how they compare:

MGO (Methylglyoxal) Rating

The MGO rating on Manuka honey indicates the concentration of methylglyoxal, the compound primarily responsible for the honey’s antibacterial properties. Higher MGO numbers reflect greater concentrations of methylglyoxal, providing an easy reference for consumers seeking specific potency levels. For example, MGO 261 indicates a moderate antibacterial strength, while MGO 512 or higher offers a more potent option. Studies confirm that methylglyoxal is the main component behind Manuka honey’s antibacterial effect, setting it apart from other honey types that rely on hydrogen peroxide for similar benefits.

UMF™ (Unique Manuka Factor) Certification

UMF™ is a broader grading system that incorporates the MGO concentration but also includes other unique compounds like DHA and leptosperin. This rating was developed by the UMF Honey Association in New Zealand as a way to assure consumers of both the quality and authenticity of Manuka honey. The UMF™ system is widely recognised and guarantees that the honey has been rigorously tested for purity, potency, and overall quality. UMF 10+ (MGO 261), for example, is considered a moderate level, while UMF 20+ (MGO 826) or higher indicates a premium-grade honey suitable for intensive health support. Honey producers wanting these certificates must first be granted a license by the UMFHA before the UMF grade can be shared on their product label.

In summary, the MGO rating offers a straightforward indication of the honey’s antibacterial strength through its methylglyoxal content, whereas the UMF certification provides a broader measure of quality, covering other beneficial compounds. Together, they offer a comprehensive view of the honey’s potency and authenticity, making it easier for consumers to choose a product suited to their needs.

Why UMF™ Certification Matters

When shopping for Manuka honey, the UMF (Unique Manuka Factor) certification is a critical marker of quality and authenticity. Not all Manuka honeys are equal, and the UMF rating provides an added layer of assurance for consumers. Here’s why UMF certification is valuable and what it indicates:

1. Verifies Authenticity and Quality
   UMF is a registered quality mark overseen by the UMF Honey Association in New Zealand. This certification ensures that the honey is not only genuine Manuka but also meets stringent quality standards that encompass its origin, purity, and potency. The UMF mark guarantees that the honey has been tested for specific markers, including methylglyoxal (MGO), DHA (a precursor to MGO), and leptosperin, a compound unique to Manuka nectar.
2. Assures Potency and Health Benefits
   While the MGO rating specifically indicates the concentration of methylglyoxal, the UMF rating offers a comprehensive assessment of the honey’s therapeutic potency. The UMF scale is broader, encompassing other compounds that contribute to Manuka honey’s effectiveness. Research shows that these compounds work synergistically, meaning their combined presence enhances the honey’s natural antibacterial and anti-inflammatory properties. UMF ratings range from UMF 5+ for general wellness to UMF 20+ and higher for potent, therapeutic-grade honey.
3. Recognised Global Standard
   UMF certification is recognised worldwide, particularly in countries where Manuka honey is valued for its medicinal properties. This recognition gives consumers confidence that they are purchasing a premium product that meets rigorous quality standards. The UMF Honey Association requires all certified producers to follow specific harvesting, processing, and labelling practices to protect the integrity of the product and ensure it meets or exceeds international expectations.

UMF certification matters because it goes beyond MGO levels to guarantee that consumers receive a high-quality, authentic, and effective product. This certification helps differentiate premium Manuka honey from lower-quality options, offering reassurance to those who prioritise quality and efficacy.
