Manuka honey, renowned for its potent antibacterial properties, owes much of its unique power to a compound called methylglyoxal (MGO). Understanding MGO is key to appreciating the therapeutic benefits of high-quality Manuka honey. This article will delve into what MGO is, how it's measured, and why it matters.

What is Methylglyoxal (MGO)?

MGO is a naturally occurring compound found in many types of honey. However, Manuka honey from New Zealand boasts significantly higher concentrations of MGO than other honeys. It's this elevated MGO level that contributes to Manuka honey's exceptional antimicrobial activity. MGO is a reactive dicarbonyl compound, meaning it interacts readily with other molecules. This reactivity is what gives it its potent antibacterial properties. It's not just about the presence of MGO, but its concentration which determines the honey's potency.

How is MGO Measured in Manuka Honey?

The MGO level in Manuka honey is measured in milligrams per kilogram (mg/kg), often simplified to just mg/kg or even mg. You'll frequently see this expressed as an MGO rating on Manuka honey labels. For example, a honey labeled "MGO 300+" contains at least 300 mg/kg of methylglyoxal. The higher the MGO number, the greater the honey's potential antibacterial power. This concentration is a significant factor in determining the honey's quality and therapeutic benefits.

Understanding Different MGO Levels

Low MGO (under 100 mg/kg): These honeys still possess some antimicrobial properties, but they are less potent than those with higher MGO levels.
Medium MGO (100-300 mg/kg): These honeys offer a noticeable increase in antimicrobial activity.
High MGO (300+ mg/kg): Honeys in this range demonstrate strong antimicrobial effects and are often sought after for their therapeutic potential.
Very High MGO (500+ mg/kg and above): These honeys represent the highest levels of MGO and typically command a premium price.

It's important to note that the MGO level isn't the only factor influencing Manuka honey's quality. Other beneficial compounds are also present.

Why is MGO Important?

The significance of MGO lies in its potent antibacterial activity against a broad spectrum of bacteria, including those resistant to conventional antibiotics. This characteristic makes Manuka honey a promising natural remedy for various conditions. Many studies have explored the potential of MGO in wound healing, treating infections, and even soothing sore throats. The high MGO concentration distinguishes Manuka honey from other honeys, emphasizing its unique therapeutic value.

Potential Benefits Linked to High MGO Manuka Honey (Note: More research is needed to confirm these benefits fully):

Wound Healing: MGO may help accelerate the healing process by inhibiting bacterial growth and reducing inflammation.
Combating Infections: Its broad-spectrum antibacterial action may help fight various infections.
Oral Health: Some studies suggest it may help combat oral bacteria.
Gut Health: Preliminary research suggests potential benefits for gut health, though more studies are needed.

Choosing Manuka Honey Based on MGO

When selecting Manuka honey, pay close attention to the MGO rating. Ensure the product is independently tested and verified to guarantee the accuracy of the MGO level. Reputable brands often provide certificates of analysis to substantiate their claims. Look for independent laboratory testing to ensure the MGO level stated on the label is accurate. Don't let marketing claims alone convince you; always verify independently.

Conclusion: MGO - A Key to Manuka Honey's Power

Methylglyoxal (MGO) is a key component responsible for Manuka honey's renowned antibacterial properties. Understanding MGO levels helps consumers choose high-quality honey with strong therapeutic potential. While more research is ongoing, the evidence supports the significant role MGO plays in the effectiveness of Manuka honey. Remember to always consult with a healthcare professional before using Manuka honey for medicinal purposes.
