The Power of MGO: What Makes Mānuka Honey So Effective?

The power of Mānuka honey comes from MGO (methylglyoxal) - a naturally occurring compound that gives Mānuka its unique antibacterial properties. The higher the MGO number, the more potent the honey.

At Honestly, we let nature lead. Our MGO-certified Mānuka honey is harvested with care in New Zealand’s untouched Northland - where bees do what they do best, and every jar delivers real, measurable benefits.

🌿 What Is MGO - and Why Does It Matter?

MGO stands for methylglyoxal, a bioactive compound found in high concentrations only in genuine Mānuka honey. It’s what gives Mānuka its scientifically backed antibacterial, antimicrobial, and wound-healing powers.

Unlike regular honey (which may contain trace amounts of hydrogen peroxide-based activity), Mānuka honey’s non-peroxide activity (NPA) - driven by MGO - makes it uniquely:

• Stable over time.

• Heat - and light-resistant.

• Effective even when diluted or applied topically.

🔬 Where Does MGO Come From?

MGO begins as dihydroxyacetone (DHA) - a naturally occurring compound found in the nectar of the Mānuka flower (Leptospermum scoparium). As the honey matures in the hive, DHA slowly converts into MGO.

The result? A honey with scientifically measurable potency - and the reason we label our jars with clear, certified MGO levels.

🧪 What Do MGO Numbers Mean?

Every Honestly jar is tested and certified for MGO content - and each number tells you how strong the honey’s antibacterial properties are.

💪 How Does MGO Work in the Body?

1. Antibacterial Properties

MGO fights harmful bacteria by disrupting cell structures, which may help with:

• Sore throats.

• Gut imbalances.

• Oral hygiene.

• Wound protection.

2. Antioxidant Support

Mānuka is rich in phenolic compounds, which may help reduce oxidative stress and inflammation.

3. Topical Skin Benefits

When applied directly, high-MGO honey may support wound healing, minor burns, and acne-prone skin.

🐝 Why Honestly Uses Certified MGO Ratings

Not all Mānuka honey is created equal - and not all labels are trustworthy. At Honestly, we:

• Independently test every batch.

• Clearly display MGO levels on every jar.

• Work only with trusted New Zealand beekeepers.

• Never mix, blend, or dilute our honey.

This means what you see on the label is what you get - every time.
