Manuka Honey: What Makes It Different, and How to Choose a Real One

Manuka honey isn't just expensive honey. Its unique compound, MGO, gives it antibacterial properties regular honey lacks. Here's what the research supports, what the labels mean, and how to spot a fake.

All honey has some natural antibacterial activity, but manuka honey is in a category of its own. It comes from bees that feed on the flowers of the manuka bush, native to New Zealand and parts of Australia, and it contains a compound that regular honey has in only tiny amounts. That compound is why hospitals use medical-grade manuka honey in wound dressings, and why it's become a staple in holistic medicine cabinets.

What Makes Manuka Different: MGO

The nectar of the manuka flower contains a compound that turns into methylglyoxal (MGO) as the honey matures. MGO is responsible for most of manuka's distinctive antibacterial activity, and unlike the hydrogen peroxide activity found in regular honey, it's relatively stable. The more MGO, the stronger the honey's antibacterial effect, and the higher the price.

Reading the Label: MGO and UMF

Because manuka is expensive, it's one of the most counterfeited foods in the world. Two rating systems help you know what you're getting:

• MGO rating: the measured amount of methylglyoxal, in milligrams per kilogram. MGO 100+ is mild, MGO 263+ is a good everyday strength, and MGO 514+ and 829+ are high-potency.
• UMF (Unique Manuka Factor): a certification from New Zealand's UMF Honey Association that tests for MGO plus other markers that confirm authenticity. Roughly, UMF 10+ matches MGO 263+, UMF 15+ matches MGO 514+, and UMF 20+ matches MGO 829+.

How to choose a real one:

• Look for a UMF or MGO number, not vague terms like "active" or "bio-active"
• Choose honey produced and packed in New Zealand
• Check for a batch number you can trace
• Expect to pay more: very cheap "manuka" is usually blended or mislabeled

For everyday use, UMF 10+ or MGO 263+ is a good balance of strength and price.

What the Research Supports

• Wound and burn care. This is manuka's strongest evidence. Medical-grade manuka honey dressings have been cleared by the FDA for wound care, and reviews have found honey may help some burns and wounds heal faster than certain conventional dressings. Note the words medical-grade: those products are sterilized. Kitchen honey isn't sterile and shouldn't go on open wounds.
• Coughs and sore throats. Research on honey in general, including a Cochrane review, shows it can ease coughs in children over one year old and adults, often as well as common over-the-counter cough medicine. Manuka's thick texture and antibacterial activity make it a popular choice for sore throats.
• Oral health. Small studies suggest manuka may reduce plaque and gum inflammation.
• Gut health. Manuka shows antibacterial activity in lab studies against bacteria like H. pylori, and it contains compounds that may feed good gut bacteria. But human studies for gut conditions have been small and mixed, so this is promising rather than proven.

How People Use It

• Daily: a teaspoon on its own, in warm (not boiling) tea, or over yogurt or fruit
• Sore throat: a spoonful taken slowly so it coats the throat
• Skin: small blemishes or dry patches, using a clean spoon to avoid contaminating the jar, or a medical-grade manuka gel
• Wounds: use medical-grade, sterile manuka products, and see a provider for deep, large, or infected wounds

Safety

• Never give any honey to a baby under 12 months. Honey can contain botulism spores that are dangerous to infants.
• It's still sugar. People managing blood sugar or diabetes should count it like any other sweetener.
• Allergies: avoid it if you're allergic to bees, pollen, or honey.
• It's not a replacement for antibiotics when a doctor says you need them.
