MGO 640 indicates a high level of methylglyoxal, the compound behind Manuka honey's antibacterial properties. Learn what the number means, how it compares to other strengths, and who should choose it.

Quick Answer

MGO 640 means the honey contains at least 640 mg/kg of methylglyoxal, the compound responsible for Manuka honey's antibacterial activity. It's a high-strength option, suitable for targeted wellness support, and typically costs more than lower MGO honeys.

When you see MGO 640 on a jar of Manuka honey, it's a shorthand for potency. MGO stands for methylglyoxal, the naturally occurring compound that gives Manuka honey its distinctive antibacterial properties. The higher the number, the more methylglyoxal is present, and the stronger the honey's antibacterial action.

But what does that mean in practice? Should you choose 640 MGO over a lower or higher strength? This guide breaks down the meaning of MGO, how 640 compares to other ratings, and who might benefit most from this potent honey.

What Does MGO Mean in Manuka Honey?

MGO is an abbreviation for methylglyoxal, a natural compound found in high levels in Manuka honey. Methylglyoxal is responsible for the honey's antibacterial properties, which is why it's considered a powerful choice for natural wellness. The MGO number on the label indicates the minimum amount of methylglyoxal in milligrams per kilogram of honey.

For example, a jar labeled MGO 640 contains at least 640 mg/kg of methylglyoxal. This number is measured by an independent lab, so you can trust that the potency is verified. The higher the MGO number, the more concentrated the antibacterial compound, and the stronger the honey's potential effects.

  • MGO is a measure of methylglyoxal content, not a flavor or texture rating.
  • Higher MGO numbers indicate stronger antibacterial properties.
  • MGO ratings are independently tested for accuracy.

How Does MGO 640 Compare to Other Strengths?

Manuka honey is available in a range of MGO strengths, from low (like MGO 70) to high (like MGO 640 or even higher). MGO 640 is considered a high-strength option, suitable for those who want more potent antibacterial support. Lower MGO honeys, like MGO 140 or MGO 240, are milder and often used for everyday wellness or as a natural sweetener.

The choice depends on your needs. If you're looking for a daily spoonful for general wellness, a lower MGO might be sufficient. But if you want a more concentrated product for targeted support, MGO 640 offers a significant boost. It's also worth noting that higher MGO honeys tend to be more expensive, so you'll want to balance potency with your budget.

  • MGO 640 offers more antibacterial potency than lower strengths like MGO 140 or 240.
  • Lower MGO honeys are often more affordable and suitable for daily use.
  • Consider your wellness goals when choosing a strength.

Who Should Choose MGO 640?

MGO 640 is a good choice for those who want a high-strength Manuka honey for occasional wellness support, such as during seasonal challenges or when you feel run down. It's also popular among athletes or active individuals who want a potent natural product. However, it may be more than you need if you're simply looking for a daily spoonful to support general health.

If you're new to Manuka honey, you might start with a lower MGO and gradually increase as you learn how your body responds. MGO 640 is a substantial step up from entry-level strengths, so it's worth considering your specific needs before committing to a jar.

  • Ideal for targeted wellness support or when you need a stronger antibacterial action.
  • Athletes and active individuals may prefer higher MGO for recovery.
  • New users might start with a lower MGO to gauge tolerance.
