Manuka Honey UMF: An 8-Point Guide to UMF and MGO Grades and Choosing Genuine Honey

Manuka Honey UMF: What Do the Numbers on the Jar Mean?

The first time you shop for Mānuka, you will see numbers such as 5+, 10+, 12+ and 15+, next to the letters UMF or MGO. These numbers are not marketing decoration. They measure the quality and strength of the honey. This guide explains Manuka honey UMF grading in plain language and helps you pick the right grade for your needs and budget.

What Is Mānuka Honey?

Mānuka honey is made by bees that collect nectar from the flowers of the Mānuka bush, which grows in New Zealand. It has a dark amber colour, a thick texture and a strong, slightly bitter taste.

Most importantly, it contains a natural compound called methylglyoxal (MGO) at much higher levels than other honeys. That compound is the reason scientists are interested in Mānuka, because it gives the honey stronger activity against some bacteria in laboratory tests compared with ordinary honey.

What UMF Means

UMF stands for Unique Mānuka Factor. It is an independent grading system run by the UMF Honey Association in New Zealand. It does not only measure MGO. It also tests authenticity markers such as leptosperin and DHA, and checks freshness by measuring HMF.

So the UMF logo on a jar means the honey has passed independent laboratory testing that confirms it is genuine New Zealand Mānuka and that its strength matches the number printed on the label. Brands can only use the logo under licence with a registered number.

What Is MGO and How Does It Relate to UMF?

MGO is the methylglyoxal content in milligrams per kilogram of honey. For example, MGO 354+ means at least 354 mg in every kilogram. There is an approximate conversion between the two systems: UMF 12+ is roughly equal to MGO 354+, which is why brands like Comvita print both numbers on the label.

In short, MGO tells you about one compound, while UMF is a broader certificate that also covers authenticity and freshness.

Which Grade Should You Choose?

For regular daily use, many people prefer grades between 10+ and 15+. UMF 12+ is a good balance point: it is clearly stronger than the low grades and better value than the very high ones. Grades of 20+ cost much more and are usually used in small amounts.

A trusted example is Comvita Manuka Honey UMF 12+ MGO 354+ 500g, a raw honey from a New Zealand company that has kept bees since 1974.

How to Spot Genuine Mānuka Honey

• Look for the UMF logo and a clear grade number on the label.
• Check for “Product of New Zealand” – certified Mānuka is packed there.
• Inspect the batch number, expiry date and the seal on the lid.
• Be wary of vague words such as “Active” without a certified number.
• Buy from a trusted pharmacy rather than unknown sellers.

Remember that crystallisation or a creamy texture is normal in raw honey and does not mean it is fake.

Manuka Honey UMF FAQ

Is a higher UMF grade always better?

A higher grade means more MGO, but it is not necessary for everyone. Regular, moderate use matters more than chasing the highest number.

What is the difference between UMF and MGO?

MGO measures a single compound, while UMF is a broader certification that also tests authenticity and freshness.

Does Mānuka honey need to be refrigerated?

No. Keep it at room temperature away from sunlight. The fridge only makes it hard to use.

The strength of Mānuka honey varies by grade, and no grade is a treatment for disease. Never give honey of any kind to babies under 12 months. People with diabetes should count honey as part of their meal plan. For more information see the UMF Honey Association.
