For a sore throat, half a tablespoon to one tablespoon of manuka honey per day is the standard recommendation. You can take it all at once or split it into two or three smaller doses throughout the day, letting each spoonful coat your throat slowly before swallowing.
How to Take It for Best Results
You have a few options: swallow it straight off the spoon, stir it into warm water with lemon, or mix it into herbal tea. Taking it straight gives your throat the most direct coating, which is what provides that immediate soothing effect. If you prefer it in a drink, use warm liquid rather than boiling water. High temperatures won’t destroy the key antibacterial compound in manuka honey (it’s heat-stable), but they can break down other beneficial enzymes.
Letting the honey linger on your throat matters more than how much you take. A slow swallow coats the inflamed tissue and keeps the honey in contact with it longer. If you’re splitting your dose across the day, a teaspoon in the morning and another before bed is a practical approach, since nighttime is when sore throat discomfort and coughing tend to peak.
Why Manuka Honey Works on Sore Throats
All honey has some antimicrobial properties, but manuka honey contains a naturally occurring compound called methylglyoxal (MGO) that gives it significantly stronger antibacterial activity. MGO disrupts bacterial cells in different ways depending on the type of bacteria: it can interfere with cell division in some species and break down the structural proteins of others. This dual action is part of why manuka honey performs well against a range of throat pathogens.
A well-known Penn State study found that honey given before bedtime reduced the severity, frequency, and bothersome nature of nighttime cough from upper respiratory infections better than dextromethorphan, the cough suppressant found in many over-the-counter cold medications. Notably, dextromethorphan performed no better than no treatment at all, while parents consistently rated honey as significantly more effective for symptom relief and sleep quality.
What UMF or MGO Rating to Look For
Not all manuka honey is equally potent. The UMF (Unique Manuka Factor) rating on the label corresponds directly to the MGO concentration inside the jar. For sore throat relief, look for UMF 10+ or higher. Lab research has shown that manuka honey at this threshold and above demonstrates meaningful antibacterial effects, and UMF 20+ has proven effective even against drug-resistant bacterial strains.
Lower-rated manuka honey (UMF 5+, for example) still tastes good and has some benefit, but if you’re specifically trying to fight a sore throat, the higher ratings deliver more of the antibacterial activity you’re paying for. Manuka honey is expensive compared to regular honey, so getting the right potency matters.
Who Should Be Cautious
Never give honey of any kind to a child under 12 months old. Honey can contain spores from the bacterium that causes infant botulism, a serious form of food poisoning that affects nerve function and can lead to muscle paralysis. After a child’s first birthday, honey is considered safe.
If you have type 2 diabetes, be mindful of your intake. Honey has a glycemic index of 50 (lower than table sugar at 80), but it still raises blood glucose. One tablespoon contains roughly 17 grams of carbohydrates. A small Turkish study found that people with type 2 diabetes who consumed 5 to 25 grams of honey daily for four months actually saw improvements in their long-term blood sugar markers, but those who consumed higher amounts saw those markers rise. If you use insulin or closely track carbohydrates, account for the honey in your daily totals.
Storing It to Keep It Effective
Store manuka honey in a cool, dark spot like a pantry or kitchen cupboard, ideally between 50 and 77°F. Keep it away from windows, stovetops, and direct sunlight. The MGO that gives manuka its antibacterial punch is stable even under heat, so a warm day won’t ruin its potency. But other beneficial enzymes in the honey are more delicate and degrade with temperature swings. A sealed jar stored properly will maintain its quality for years.
