Which MGO Manuka Honey Is Right For Me?

Choosing the right strength of Mānuka honey can feel confusing with so many numbers on the label. This guide explains exactly what MGO stands for, what the grades mean in practice, and which strength of natural Mānuka honey is best suited to your lifestyle and wellness goals.

 

 

What Does MGO Stand For in Mānuka Honey?

MGO stands for Methylglyoxal, a naturally occurring compound found in genuine Mānuka honey. It is the primary component responsible for the honey's potent antibacterial and anti-inflammatory properties, and it is what sets authentic Mānuka honey apart from regular natural honey varieties.

The MGO number on every jar of Mānuka honey represents the concentration of Methylglyoxal measured in milligrams per kilogram of honey. For example, a jar labelled MGO 525+ contains a minimum of 525mg of Methylglyoxal per kilogram. The higher that number, the stronger and more potent the honey.

At Mānuka Lab, every jar of Mānuka honey is independently tested and certified for its MGO level, giving you confidence that the product you are purchasing is genuine, traceable, and meets the strict quality standards we uphold.

How Is MGO Formed in Natural Mānuka Honey?

MGO is not added to Mānuka honey; it forms naturally during the honey-making process. Bees collect nectar from the Mānuka plant (Leptospermum scoparium), also known as the Mānuka bush, which grows natively across New Zealand. That nectar contains a compound called dihydroxyacetone (DHA), which gradually converts into Methylglyoxal as the honey matures. This natural conversion continues during storage, meaning MGO levels can increase over time.

This is also why the Mānuka bush and its growing region matter so much. Our honey is sustainably harvested from bees foraging exclusively on the Mānuka bush in the remote East Cape region of New Zealand, one of the most pristine environments in the world.

Why Does the MGO Level Matter?

The MGO level is the most reliable, science-backed indicator of a Mānuka honey's potency. Unlike regular honey, which relies on hydrogen peroxide for mild antimicrobial activity, real Mānuka honey derives its unique strength from Methylglyoxal. This non-peroxide activity (NPA) is what gives Mānuka honey its distinctive, measurable properties that researchers and consumers rely on.

In simple terms, a higher MGO rating means greater antibacterial strength, which in turn makes it better suited to targeted wellness support. A lower MGO rating offers a gentler effect that is ideal for everyday use as part of a balanced diet.

 

MGO Mānuka Honey Grades Explained

The table below gives a quick overview of the most common MGO grades available at Mānuka Lab and the typical use case for each.

MGO 40+ to 100+ (Mild, Everyday Use)

This is the ideal starting point for anyone new to natural Mānuka honey. It is mildly stronger than standard supermarket honey, yet gentle enough for daily consumption. Use it stirred into warm drinks, drizzled over porridge or yoghurt, or spread on toast as part of your morning routine. MGO 100+ is a particularly popular entry-level option that introduces the benefits of Methylglyoxal without an intense flavour.

MGO 300+ (Moderate Support)

A step up in potency, the MGO 300+ grade is well suited to those seeking more pronounced support during times of seasonal change or additional stress on the body. It carries a richer, more distinctive taste than lower grades and can be taken by the spoonful or incorporated into recipes.

MGO 525+ (High Strength)

MGO 525+ is a high-strength Mānuka honey with elevated Methylglyoxal concentrations. It is a popular choice during the winter months, particularly for people who are susceptible to seasonal illness. The taste is notably rich and intense, reflecting its higher concentration of natural compounds from the Mānuka plant. While it is not a medical treatment, many people turn to this grade when they want robust daily support.

MGO 850+ to 1125+ (Premium Grade)

The premium end of the MGO scale, these grades contain some of the highest concentrations of Methylglyoxal available in certified Mānuka honey. They are often selected by experienced Mānuka users who want intensive support or specific applications. At this level, the honey carries a powerfully intense flavour and a deep amber colour.

What Are the Key Markers of Real Mānuka Honey?

Due to significant global demand for real Mānuka honey, the New Zealand government introduced strict export regulations that define what can legally be labelled and sold as authentic Mānuka honey. These regulations specify a set of key markers that must be present and measurable in any certified product.

These key markers include:

• Methylglyoxal (MGO) concentration above defined thresholds
• Leptosperin, a unique compound derived from Mānuka nectar
• DHA (dihydroxyacetone), the precursor to MGO
• 2-methoxybenzoic acid, another Mānuka-specific marker
• Mānuka pollen concentration

Only honey that meets all five of these criteria can be exported from New Zealand as authentic, certified Mānuka honey. At Mānuka Lab, each batch is independently tested against these standards, ensuring that every jar of Mānuka honey we sell is the genuine article, not an imitation.

Monofloral vs Multifloral Mānuka Honey

When browsing a jar of Mānuka honey, you may notice the terms 'monofloral' and 'multifloral' on the label. Understanding the difference is important.

Monofloral Mānuka honey is produced by bees foraging primarily from densely concentrated Mānuka bush growth. This results in higher levels of the key markers associated with Mānuka, including MGO, Leptosperin, and DHA. Monofloral honey must meet stricter regulatory thresholds for these markers, making it the more potent and purer option.

Multifloral Mānuka honey is produced where bees forage from a lower density of Mānuka plants, mixed with other flowering species. It typically contains lower concentrations of MGO and the other key markers, and tends to carry a milder flavour and effect. It still meets the legal definition for Mānuka honey but at a lower threshold.

For the strongest, most reliably potent product, monofloral Mānuka honey is the preferred choice.

Which MGO Mānuka Honey Is Right For Me?

The right strength of Mānuka honey depends on what you want to use it for and your current lifestyle. Here is a simple guide to help you decide:

• For daily wellbeing and general health: Choose MGO 100+ or MGO 40+. A daily spoonful in warm water or drizzled over breakfast is an easy way to incorporate the benefits of natural Mānuka honey into your routine without an overpowering flavour.
• For seasonal and immune support: Choose MGO 300+ or MGO 525+. If you are prone to picking up colds or want additional support during the winter months, a higher MGO level provides stronger antibacterial activity. This is not a substitute for medical treatment but can be a meaningful addition to a healthy lifestyle.
• For targeted or intensive use: Choose MGO 850+ or MGO 1125+. These premium grades are best for those with specific wellness goals or who are experienced Mānuka users seeking maximum potency.

Anti-Inflammatory Properties and Other Benefits of MGO Mānuka Honey

Methylglyoxal is widely studied for its antibacterial activity, but the benefits associated with genuine Mānuka honey extend further. Research and consumer experience point to a range of properties that make real Mānuka honey a popular addition to daily wellness routines:

• Anti-inflammatory properties: Mānuka honey has demonstrated anti-inflammatory properties in research settings, making it of interest to those managing skin irritation, sore throats, and digestive discomfort.
• Gut health support: Scientific studies suggest Mānuka honey may support the gut microbiome, with some evidence pointing to benefits for digestion when consumed before meals.
• Throat and oral care: High-MGO Mānuka honey is frequently used as a natural soothing agent for sore throats. Taking a spoonful directly or mixed with warm water is one of the most common consumer uses.
• Skincare applications: The antibacterial and anti-inflammatory properties of Mānuka honey make it a popular ingredient in natural skincare, used in face masks and spot treatments.

It is important to note that while Mānuka honey is a valued natural food with well-documented properties, it is not a medicine and should not be used as a replacement for professional medical advice or prescribed treatments.

How to Store a Jar of Mānuka Honey

To preserve the MGO content and quality of your Mānuka honey, correct storage is essential:

• Keep the jar in a cool, dry place, away from direct sunlight and heat sources
• Always ensure the lid is tightly closed to prevent moisture absorption, which can dilute the honey and reduce its properties
• Do not refrigerate the honey, as cold temperatures can cause crystallisation and alter the texture
• Use a clean, dry spoon each time to prevent contamination and preserve purity

Properly stored, a jar of Mānuka honey can retain its quality and potency for an extended period. As noted earlier, MGO levels can continue to increase slightly during storage as residual DHA converts.

Potential Side Effects and Considerations

Mānuka honey is safe for most adults and older children when consumed as a food. However, there are a few considerations to be aware of:

• Allergies: Those with known allergies to bee products or pollen should exercise caution and consult a medical professional before consuming Mānuka honey.
• Blood sugar levels: Like all honey, Mānuka honey contains natural sugars that can affect blood glucose. People living with diabetes should seek guidance from their healthcare provider before adding it to their diet.
• Medication interactions: If you are undergoing medical treatment or taking prescribed medication, speak to your doctor or pharmacist before consuming high-MGO Mānuka honey regularly.
• Infants: Honey should never be given to children under 12 months of age due to the risk of infant botulism.

If you are new to Mānuka honey or moving up to a higher MGO grade, begin with a small amount and monitor your response. If you have any health concerns, consult a qualified healthcare professional before use.
