Discover what UMF 18+ Mānuka honey offers, how it compares to lower and higher grades, and how to use it for everyday wellness.
Mānuka honey is prized for its unique antibacterial properties, but not all jars are created equal. The UMF rating system measures the key compounds that give Mānuka honey its potency, and UMF 18+ sits at a sweet spot between everyday maintenance and targeted support. If you're curious about what this strength offers, here's a clear breakdown of its benefits and how to choose it wisely.
Whether you're new to Mānuka honey or looking to step up from a lower UMF, understanding what UMF 18+ delivers can help you decide if it's worth the investment. In this article, we'll explore the science behind the rating, how it compares to other strengths, and practical ways to use it.
What Does UMF 18+ Mean?
UMF stands for Unique Mānuka Factor, a grading system that measures the levels of three key signature compounds in Mānuka honey: leptosperin, DHA, and methylglyoxal (MGO). A UMF 18+ rating indicates a high concentration of these beneficial compounds, ensuring the honey's potency and authenticity. The higher the UMF, the stronger the antibacterial and antioxidant activity.
For context, UMF 10+ is often recommended for daily wellness, while UMF 15+ and above are considered therapeutic grades. UMF 18+ offers a robust option for those seeking more pronounced benefits without jumping to the highest strengths like UMF 20+ or UMF 25+.
- UMF 18+ honey contains at least 400 mg/kg of methylglyoxal, the compound responsible for its antibacterial effects.
- Look for the UMF trademark on the label to ensure the honey has been independently tested and certified.
Key Benefits of UMF 18+ Mānuka Honey

UMF 18+ Mānuka honey is known for its powerful antibacterial and antioxidant properties. It can help soothe sore throats, support digestive health, and boost the immune system. The high MGO content makes it effective against a range of bacteria, making it a popular choice for natural wellness enthusiasts.
Additionally, this strength is often used to support skin health. Applied topically, it can help with minor wounds and blemishes, though you should always patch test and consult a professional for serious skin conditions. For everyday use, a teaspoon a day can be a simple way to incorporate it into your routine.
- Take a spoonful on an empty stomach in the morning for digestive support.
- Mix it into warm (not boiling) water or herbal tea for a soothing drink.
UMF 18+ vs. UMF 20+: Which Should You Choose?
The main difference between UMF 18+ and UMF 20+ lies in the concentration of active compounds. UMF 20+ has a higher MGO content, typically around 830 mg/kg, compared to UMF 18+ which has at least 400 mg/kg. This means UMF 20+ is even more potent, but it also comes with a higher price tag.
For most people, UMF 18+ offers an excellent balance of efficacy and cost. It's strong enough for therapeutic use but more accessible than the premium UMF 20+ grades. If you're managing a specific health condition or prefer maximum potency, UMF 20+ might be worth the extra investment. Otherwise, UMF 18+ is a practical choice for daily wellness.
- If you're on a budget, UMF 18+ provides significant benefits at a lower cost than UMF 20+.
- For occasional use, UMF 18+ is more than sufficient; for daily intensive use, consider UMF 20+.
How to Use UMF 18+ Mānuka Honey
Incorporating UMF 18+ Mānuka honey into your routine is easy. You can take it straight off a spoon, add it to smoothies, or drizzle it over oatmeal. Because high heat can degrade the beneficial enzymes, avoid adding it to boiling liquids. Instead, stir it into warm beverages or spread it on toast after it has cooled slightly.
For targeted support, you might consider pairing it with other wellness products. For example, a daily spoonful of UMF 18+ honey alongside a Bee Propolis Extract PFL 30 can provide a complementary boost to your immune system. If you prefer convenience, the UMF 10+ Mānuka Honey Squeeze is a great option for on-the-go use, though it has a lower UMF.
- Store your honey in a cool, dry place away from direct sunlight to preserve its potency.
- If the honey crystallizes, gently warm the jar in a warm water bath – never microwave it.
UMF 18+ Mānuka honey offers a powerful yet practical option for those seeking the benefits of high-grade Mānuka honey without the premium price of UMF 20+. Whether you're using it for immune support, digestive health, or simply as a daily wellness boost, its potency and versatility make it a valuable addition to your pantry. When choosing, always look for certified UMF products to ensure you're getting genuine, high-quality honey.
