Manuka Honey MGO Chart

At Biosota Organics, we use a scientifically validated numerical grading system to measure the purity and potency of our Manuka honey—Methylglyoxal (MGO). MGO is the key bioactive compound that sets true Manuka honey apart, offering a clear, measurable indicator of its antibacterial strength and therapeutic quality.

Each batch of our high-strength, medicinal-grade Manuka honey is independently tested and certified by accredited laboratories to ensure authenticity and accuracy. Compared to standard premium honey, medical-grade Manuka contains significantly higher MGO levels, offering proven support for wound healing, burns, sore throats, oral hygiene, and even bacterial infections.

The higher the MGO rating, the greater the antimicrobial bioactivity—meaning more powerful natural benefits for your health and wellness.

We believe our customers deserve transparency and education, which is why we’ve created this comprehensive MGO chart and guide—to help you choose the right Manuka honey for your specific needs with confidence.

Manuka Honey MGO Chart Benefits

 

Markers of Authentic Australian Manuka Honey

What Is MGO in Manuka Honey?

MGO stands for Methylglyoxal, the key natural compound responsible for the potent antibacterial and therapeutic properties of authentic Manuka honey. Backed by leading Australian research, MGO is now the globally recognized standard for measuring the strength and medicinal quality of Manuka honey.

Simply put, the higher the MGO number, the stronger the honey’s ability to fight bacteria, support healing, and promote wellness. But MGO isn’t the only rating system—so where do NPA, ULF, and DHA come in?

 

What Are NPA and ULF in Manuka Honey?

NPA (Non-Peroxide Activity) reflects the honey’s antibacterial activity beyond natural hydrogen peroxide, while ULF (Unique Leptospermum Factor) is a branding term used to describe the same bioactivity. Both are used to indicate the therapeutic potency of Manuka honey, especially when it comes to wound care and immune support.

 

What Is DHA in Manuka Honey?

DHA (Dihydroxyacetone) is a compound found only in the nectar of the Manuka flower. It’s the precursor to MGO—meaning that over time, DHA naturally converts into MGO as the honey matures.

A honey with high DHA but low MGO is typically young and still developing potency. When DHA and MGO levels are balanced, the honey has fully matured, reaching its peak strength and therapeutic value. This natural aging process is critical in producing high-grade, medicinal-strength Manuka honey.

 

Biosota Manuka honey is unmatched in purity, potency, and flavor. Proudly crafted in Australia, our extensive range includes verified MGO levels to suit every need—from daily wellness to high-strength medicinal use. While all Manuka honey offers health benefits, it's the MGO rating that determines its therapeutic power—the higher the MGO, the greater its healing potential.

Our medical-grade Manuka honey is trusted to relieve, soothe, and support the healing of everything from skin wounds, sunburn, and cold sores to digestive issues and seasonal colds. Scientifically backed for its ability to balance gut microbiota and deliver antimicrobial, antiseptic, and anti-inflammatory effects, Manuka honey may also help reduce healing time and support immune health naturally.

We believe in the power of this golden elixir—and once you try it, you will too. Whether you’re seeking to support everyday wellness or target specific health concerns, Biosota’s MGO Manuka honey can help disinfect, draw moisture from wounds, prevent bacterial growth, and promote faster healing.

Not sure which MGO grade is right for you? Use the chart below to discover the best Manuka honey strength for your personal needs.

We suggest: MGO 30–290+

On the lower end of the MGO scale, honeys graded at MGO 150+ are a great option for a natural, everyday treat. Those closer to MGO 250+ can work well as a maintenance dose to support immunity. Biosota’s Manuka honey straws are a satisfying addition to your cuppa and a great way to maintain a daily dose.

We suggest: MGO 300–490+

Honeys graded at MGO 260+ begin to enter the realm of the minimum activity necessary for medicinal use. They can work well for bacterial coughs, sore throats, and minor cuts, scrapes, bruises and sunburn.

High Medicinal Strength

We suggest: MGO 500–990+

Honeys graded at MGO 500+ have a higher potency than minimal medicinal grade honeys and are potentially more effective for maintaining digestive health. Studies have also shown that highly graded Manuka honey, used in combination with other methods, significantly reduces the severity and duration of colds & flu symptoms.

We suggest: MGO 1000–1900+

Reaching the higher end of the MGO rating system, MGO 1000+ honeys are quite potent, which may increase the efficiency of relieving chronic and more complex health issues such as gut health, bacterial infections, ulcers, wounds and burns.

As these ratings suggest, these honeys are rarer and are sought after for their potency and effectiveness in addressing concerns mentioned above. Biosota’s High MGO 1717+ is one of the highest-grade medicinal Manuka honeys on the market.

We suggest: MGO 2200+

Our Highest Grade MGO 2200+ is the rarest, strongest, and highest MGO-rated Manuka honey in the world. Limited edition - only 500 jars ever produced.
