How to Read Manuka Honey Labels: MGO, UMF, and Everything In Between

Quick Answer

To read a Manuka honey label, focus on the MGO number (methylglyoxal content) or UMF rating, check for 'monofloral' vs 'multifloral', and look for a certification statement. For everyday use, an MGO 70 or 100 is a great starting point; for stronger antibacterial support, choose MGO 400 or above.

Standing in front of a shelf of Manuka honey can feel like decoding a secret language. Numbers like MGO 70, UMF 10+, and terms like 'monofloral' seem to promise different levels of benefits, but what do they actually mean for your health and your wallet?

This guide breaks down the key parts of a Manuka honey label so you can compare pots with confidence. We'll focus on the two main rating systems—MGO and UMF—explain the difference between monofloral and multifloral honey, and give you concrete rules for choosing the right grade for your needs.

What Does the MGO Number Mean?

MGO stands for methylglyoxal, the natural compound largely responsible for Manuka honey's unique antibacterial activity. The number on the label—like MGO 70 or MGO 840—tells you the guaranteed minimum level of methylglyoxal in milligrams per kilogram. Higher numbers mean a more potent honey, which is why MGO 840 is significantly stronger than MGO 70.

Methylglyoxal is what sets Manuka honey apart from regular honey. While all honey has some antibacterial properties, the methylglyoxal in Manuka is much higher, and it's the standard by which the industry measures strength. When you see an MGO rating, you know exactly how much of that key compound is present, which helps you match the honey to your health goals.

• MGO 70–100: gentle, everyday use—good for toast, tea, or a daily spoonful.
• MGO 200–400: moderate potency, often chosen for general wellness and immune support.
• MGO 600–900: high potency, typically used for targeted antibacterial purposes or more intensive wellness routines.

UMF vs. MGO: What's the Difference?

UMF (Unique Manuka Factor) is another rating system, developed in New Zealand, that measures the unique markers of authenticity and quality. It includes methylglyoxal but also other signature compounds. The scale roughly corresponds to MGO, with UMF 10+ equating to around MGO 400, UMF 15+ around MGO 850, and so on. Both systems indicate potency, but they test different things.

In practice, you don't need to convert between the two. Just know that a higher number in either system means stronger honey. If a label shows both, great—you have two ways to verify quality. If it shows only one, that's fine too. The key is consistency: always look for a number you recognize, and avoid jars that list no rating at all.

• UMF 10+ ≈ MGO 400; UMF 15+ ≈ MGO 850. Use any rating you're comfortable with.

Monofloral vs. Multifloral: Why It Matters

Monofloral Manuka honey comes primarily from Manuka flowers, giving it a higher concentration of the unique markers and typically a higher MGO rating. Multifloral honey is a blend of Manuka and other floral sources, resulting in a milder, more variable profile. Both are genuine Manuka honey, but they serve different purposes.

If you're looking for the most consistent, potent product—say for targeted wellness—a monofloral honey like our 840 MGO Monofloral is a clearer choice. For everyday use, a multifloral option at a lower MGO is often more economical and still offers the characteristic taste and benefits. The label should clearly state which type it is; if it doesn't, check the brand's transparency.

• Monofloral: higher methylglyoxal concentration, stronger activity, usually more expensive.
• Multifloral: milder flavor and potency, versatile for daily use, often more budget-friendly.

What Else Should You Check on a Label?

Look for a certification logo or a statement that the honey was 'tested and certified' for authenticity. Manuka Doctor certifies every batch and lists the MGO strength on the front of the pot, so you know exactly what you're getting. Also check the origin—genuine Manuka honey is packed in New Zealand, though some brands import and pack elsewhere.

Be cautious of labels that use vague terms like 'active' without a number, or that claim 'high strength' without providing a MGO or UMF rating. These are marketing terms, not quality indicators. A reputable brand will give you the numbers and back them with testing.

• Always look for a numeric MGO or UMF rating—numbers, not adjectives, are your guide.

Decision Rules for Choosing Your Grade

• Everyday wellness and great taste: Choose an MGO 70 or 100 for daily use—on toast, in tea, or straight off the spoon. These are gentle enough for regular consumption and taste wonderful. Good starting point for most people.
• Occasional immune support: If you want a bit more antioxidant and antibacterial support a few times a week, step up to MGO 400–600. Use a teaspoon a day as a preventive measure. Balances strength and cost.
• Intensive wellness or targeted use: For higher antibacterial activity, choose an MGO 600+ monofloral honey. Use sparingly—a 250g jar lasts longer than you'd think, and the potency justifies the price. Best when you need maximum potency.
