UMF MGO Manuka Honey: Understanding Strength and Quality |


Welcome to! In this article, we will discuss everything you need to know about UMF MGO Manuka honey and how to determine its strength. As there are no official UK guidelines for grading Manuka honey, it can be challenging to shop for the right product. However, there is a widely supported definition of authentic Manuka honey that helps us determine its quality.

What is Authentic Manuka Honey?

Authentic Manuka honey is defined by the Manuka Honey Science Definition, which establishes the minimum quantity of naturally occurring chemicals found in the nectar of Manuka flowers that must be present in the honey to be authenticated as Manuka.

According to this definition, there are two key requirements for a honey to be considered authentic Manuka:

  1. Non-peroxide activity (NPA): Manuka honey must have non-peroxide activity, which is responsible for its antibacterial properties. The presence of Methylglyoxal (MGO) is an indicator of non-peroxide activity.

  2. Marker compounds: Manuka honey should contain specific marker compounds, such as Dihydroxyacetone (DHA) and Methylglyoxal, that can only be found in the nectar of Manuka flowers.

The Manuka Honey Science Definition provides a scientific basis for determining the authenticity of Manuka honey and is widely accepted in the industry.

UMF (Unique Manuka Factor) and MGO (Methylglyoxal) Ratings

UMF and MGO are two commonly used rating systems to determine the strength and quality of Manuka honey.

UMF (Unique Manuka Factor) Rating

The UMF rating is a quality trademark and grading system that measures the non-peroxide activity of Manuka honey. It indicates the level of antibacterial potency in the honey.

The UMF rating scale ranges from 0 to 20+, with a higher rating indicating a higher level of non-peroxide activity. A UMF rating of 20+ is considered the highest quality and most potent Manuka honey.

However, at Rowse, we recognize that 83+ MGO is the official UMF threshold. Still, we choose to offer a range of Manuka honeys with ratings of 100+ MGO, 250+ MGO, and 500+ MGO for complete peace of mind. This variety allows you to determine the strength of Manuka honey that suits your needs and guarantees you are getting genuine Manuka honey.

MGO (Methylglyoxal) Rating

MGO, or Methylglyoxal, is a naturally occurring compound found in Manuka honey. It is responsible for the non-peroxide antibacterial activity of the honey.

The MGO rating indicates the concentration of Methylglyoxal in the honey and is directly related to the honey’s antibacterial potency. Higher MGO ratings signify higher levels of non-peroxide activity.

Below is a comparison of MGO ratings to NPA ratings:

  • MGO 100+ is equivalent to NPA 5+
  • MGO 250+ is equivalent to NPA 10+
  • MGO 500+ is equivalent to NPA 15+

Rowse offers a range of Manuka honeys with different MGO ratings, ensuring there is a suitable option for every individual’s needs.

Determining the Strength of Manuka Honey

Determining the strength of Manuka honey involves considering both the UMF and MGO ratings.

UMF vs. MGO: Which Rating System Should You Choose?

The choice between UMF and MGO ratings depends on personal preference and the level of non-peroxide activity desired.

If you prefer a grading system that takes into account the overall quality and authenticity of Manuka honey, UMF rating is the way to go. The UMF rating ensures that the honey meets specific standards for antibacterial potency and marker compounds.

On the other hand, if you are primarily interested in the non-peroxide antibacterial activity of Manuka honey, the MGO rating provides a straightforward measurement of Methylglyoxal concentration.

Which Strength of Manuka Honey Should You Buy?

When determining the strength of Manuka honey to purchase, consider the following factors:

  1. Intended use: Determine the purpose for which you will be using the Manuka honey. If you are using it for general health and wellness, a lower strength honey may suffice. However, for specific therapeutic uses, such as wound care or digestive issues, a higher strength honey may be more effective.

  2. Price: Consider your budget and the price difference between various strengths of Manuka honey. Higher strength honeys often come at a higher cost, so choose the strength that fits both your needs and your budget.

  3. Quality: Ensure that the Manuka honey you purchase is authentic and meets the necessary standards for non-peroxide activity and marker compounds. Look for trusted brands and check for certifications and independent testing.
