How to Choose the Best Mānuka Honey

When it comes to Mānuka honey, the label matters. Between UMF grades, MGO numbers, country of origin, and quality certifications, knowing what to look for can help you choose a product that is genuine, traceable, and suited to your everyday wellness needs. This guide breaks down how to identify high-quality Mānuka honey, what UMF and MGO really mean, and which grade may be the best fit for the way you plan to use it.

There are many Mānuka honey brands, but not all are created equal. Here’s what to look for:

• UMF Certification: Guarantees the honey is monofloral, independently tested, and free from adulteration
• Made in New Zealand: Only New Zealand Mānuka is held to MPI and UMF standards
• Grading Transparency: Look for UMF and MGO values clearly labeled
• Traceability: Top producers like Comvita trace every jar back to its hive
• Other Quality Certifications:
  • Non-GMO Project Verified
  • Certified Glyphosate Free
  • Certified Gluten Free
  • Kosher
  • Halal

Choosing the Right Grade

Not sure which Mānuka honey strength is right for you? It all depends on how you plan to use it. Lower grades are great for daily wellness and general use, while higher grades offer more potent antibacterial support for targeted needs like digestion or skin concerns. Use the guide below to help match the UMF or MGO level to your specific goals:

Mānuka Honey Grades Explained: UMF vs MGO

When shopping for Mānuka honey, it’s easy to get lost in the labels. With terms like UMF, MGO, and “multifloral” on the jar, it can be difficult to know what you’re really buying, or how strong it actually is. Not all Mānuka honey is created equal, and understanding how it's graded is key to choosing the right one for your needs. Whether you’re looking for daily wellness support or a more potent, therapeutic-grade honey, here’s what you need to know.

UMF™ (Unique Mānuka Factor)

UMF™ is the gold standard for authentic Mānuka honey. Certified by the UMF™ Honey Association in New Zealand, this rating verifies a product’s purity, potency, and authenticity. It measures four key signature compounds that are unique to genuine Mānuka:

• MGO (Methylglyoxal): The main compound responsible for Mānuka’s antibacterial activity
• DHA (Dihydroxyacetone): Naturally present in Mānuka nectar and the precursor to MGO
• Leptosperin: Found only in Mānuka nectar and a marker of authenticity
• HMF (Hydroxymethylfurfural): Indicates freshness and proper storage

To carry a UMF™ rating, the honey must also be:

• Monofloral (primarily from the Mānuka flower)
• Sourced, tested, and packed in New Zealand
• Independently verified and traceable

UMF ratings range from UMF 5+ to UMF 20+ or higher.

The higher the UMF™, the more concentrated the bioactive compounds, and the stronger the honey’s potential benefits. Unlike MGO, which measures only one compound (methylglyoxal), UMF is a more comprehensive standard. It includes MGO plus other critical markers like DHA and Leptosperin, and is independently tested and regulated in New Zealand to ensure authenticity, purity, and potency.

MGO (Methylglyoxal)

MGO is one of the key active compounds in Mānuka honey and the primary contributor to its antibacterial strength. The number on the label reflects the milligrams of MGO per kilogram of honey (e.g., MGO 263+ means 263 mg/kg).

The higher the MGO, the stronger the antibacterial potential.
However, MGO is only one part of what UMF™ measures, and doesn’t account for authenticity, freshness, or purity on its own.

What Are the Benefits of Mānuka Honey?

Whether taken by the spoonful or applied to the skin, Mānuka honey offers a wide range of benefits:

Supports Immune Health

High-grade UMF Mānuka honey is rich in MGO, which helps fight bacteria and may aid the body’s natural defenses, especially during cold and flu season.

Support Digestive Health

Known to soothe the gut, Mānuka honey may help ease symptoms of indigestion and aid digestive health.

Soothes Coughs & Sore Throats

Thanks to its thick texture and antibacterial potency, Mānuka honey is a trusted remedy for upper respiratory symptoms.

Skin & Wound Healing

Used in medical-grade settings for its ability to clean wounds and reduce inflammation, it’s also a favorite in DIY masks for acne-prone or dry skin.

Antioxidant Protection

The naturally occurring phenolic compounds found in Mānuka honey may help neutralize free radicals, associated with oxidative stress and premature aging.

Pre-workout Boost

Mānuka honey offers a clean, fast-absorbing source of natural energy, ideal before workouts or busy days, plus added wellness benefits you won’t get from typical sugars.

How to Use Mānuka Honey Every Day

Whether you're supporting immunity, looking for a natural skin remedy, or simply seeking a cleaner sweetener, Mānuka honey fits seamlessly into your everyday routine. Its versatility goes beyond the spoon, just be mindful to keep it away from high heat to maintain its full benefits.

• Daily Spoonful
  Enjoy it straight off the spoon or stir into warm water that’s cooled slightly—perfect for a gentle daily immune boost without compromising its natural potency.
• In Your Routine
  • Add to herbal teas, coffees, smoothies, or warm lemon water (once cooled to a sip-safe temperature)
  • Drizzle over yogurt, granola, or toast after serving
  • Blend into salad dressings, dips, or wellness shots—but avoid cooking or baking with it at high heat to preserve its beneficial compounds
  • Use as a natural face mask or spot treatment for skin hydration and clarity
• For Kids & Families
  Try for lower UMF grades (like 5+ or 10+) as part of a daily wellness routine.
  Note: Honey should not be given to children under 1 year of age.

FAQs About Mānuka Honey

What does Mānuka honey do?

Mānuka honey supports the immune system, soothes sore throats, aids digestion, and is used topically for wound healing and skin irritation.

How is Mānuka honey made?

Bees pollinate Mānuka flowers, which bloom only 2–6 weeks each year. Back at the hive, they transform the nectar into honey that’s naturally rich in MGO, a compound known for its antibacterial power, along with DHA (Dihydroxyacetone), Leptosperin, and HMF. These compounds are part of what makes Mānuka honey so unique, and are used to measure its quality through the UMF™ grading system.

What makes Mānuka honey unique?

Its non-peroxide antibacterial activity, derived from MGO and other phytochemicals, sets it apart from other honey types.

Is UMF better than MGO?

Yes, UMF is a more comprehensive standard that includes MGO, DHA, and Leptosperin. It’s independently verified and regulated in New Zealand.

Why should you look at more than the MGO factor?

While MGO (methylglyoxal) is a key indicator of Mānuka honey’s antibacterial strength, it only tells part of the story. UMF™ (Unique Mānuka Factor) is a more complete and reliable standard that ensures you're getting a pure, potent, and genuine New Zealand Mānuka honey.

The UMF™ rating includes four critical markers:

• MGO – Measures antibacterial strength.
• Leptosperin – A naturally occurring compound unique to Mānuka, and a key marker of authenticity that cannot be added artificially.
• DHA (Dihydroxyacetone) – A precursor to MGO that ensures the honey will retain its potency over time.
• HMF (Hydroxymethylfurfural) – Indicates whether the honey has been overheated or aged, which can reduce effectiveness and shelf life.

Brands that use MGO-only labeling don’t account for authenticity or long-term quality. UMF™ is the only globally recognized and independently verified system that tests for all four factors and ensures the honey was harvested, packed, and tested in New Zealand, where real Mānuka honey comes from.

When you see the UMF™ mark, you know you’re getting the real deal.

Where can I buy real Mānuka honey?

Only buy honey that’s UMF™ certified and packed in New Zealand. Shop directly from Comvita or verified retailers.
