Manuka honey and raw, unpasteurized honey are the two best options for acid reflux relief. Both are thick enough to coat the esophagus and reduce the burning sensation of stomach acid washing upward, but Manuka honey has the strongest clinical backing so far. A small 2024 study found that people with GERD who took Manuka honey three times daily experienced reduced heartburn, less regurgitation, and improvement in esophageal inflammation.
Why Honey Helps With Acid Reflux
Honey’s main advantage over other home remedies is its thickness. At body temperature, honey is roughly 126 times more viscous than water. When it travels down your esophagus, it doesn’t just pass through. It clings to the lining and forms a temporary coating that acts as a barrier between your tissue and rising stomach acid.
Lab testing published in The BMJ demonstrated this effect: when 5 ml of honey was poured down a vertical glass tube kept at body temperature, nearly 1 ml of honey was still coating the inside of the tube after almost four minutes. Water left no residue at all. That sticky, lingering quality is what gives honey its protective effect, creating a physical shield over irritated esophageal tissue rather than neutralizing acid chemically the way an antacid does.
Honey also contains natural hydrogen peroxide and other antibacterial compounds, which may help if the esophageal lining is already inflamed or damaged from repeated acid exposure.
Manuka Honey
Manuka honey, produced by bees that pollinate the Manuka bush in New Zealand, is the only type of honey studied directly for GERD in a clinical trial. In the 2024 study, participants took 5 grams (roughly one teaspoon) of Manuka honey three times per day. The results showed meaningful reductions in both heartburn and regurgitation, along with visible improvement in esophagitis (inflammation of the esophageal lining). Researchers attributed the longer-lasting relief partly to Manuka’s viscosity, which allowed it to coat the esophagus more effectively than thinner liquids.
Manuka honey also contains unique antibacterial compounds beyond the hydrogen peroxide found in regular honey. This is why medical-grade Manuka honey is already used in wound care. Whether those extra antimicrobial properties contribute to reflux relief specifically isn’t fully established, but they’re unlikely to hurt if your esophagus is already irritated.
Look for Manuka honey with a UMF (Unique Manuka Factor) or MGO rating on the label. Higher numbers indicate stronger antibacterial activity. For acid reflux purposes, a mid-range product (UMF 10+ or MGO 250+) is a reasonable starting point, since the clinical study focused on standard Manuka honey rather than the most potent medical-grade varieties.
Raw, Unpasteurized Honey
If Manuka honey’s price tag is a barrier (it typically costs several times more than regular honey), raw, unpasteurized honey is the next best option. Raw honey retains its natural enzymes, antioxidants, and beneficial compounds that are destroyed during pasteurization. The commercially processed honey you’ll find in squeeze bottles at most grocery stores has been heated and filtered, stripping out much of what makes honey potentially therapeutic.
Any raw honey will still have the viscosity needed to coat your esophagus. The key difference from Manuka is that raw honey lacks the additional antibacterial compounds unique to the Manuka plant, and it hasn’t been tested in GERD-specific clinical trials. That said, the physical coating mechanism works the same way regardless of the honey variety.
How to Take It
The most straightforward approach is one teaspoon (about 5 ml) of honey swallowed on its own or stirred into warm water. Taking it 30 minutes before meals can help coat the esophagus before food triggers acid production. You can also take a teaspoon before bed if nighttime reflux is your main problem, since lying down makes acid more likely to travel upward.
Some people mix honey with warm water and a small amount of ginger or turmeric for additional anti-inflammatory effects. If you go this route, keep the water warm rather than hot, since very hot liquids can degrade honey’s beneficial enzymes. Two to three doses per day is the general range used in both the Manuka study and traditional preparations.
What Honey Won’t Do
No clinical studies have directly compared honey to standard acid reflux medications like antacids or proton pump inhibitors. Honey coats and soothes, but it doesn’t reduce acid production the way medications do. For occasional heartburn, honey can provide real relief. For chronic GERD with frequent symptoms or esophageal damage, it’s better used alongside medical treatment rather than as a replacement.
Honey is also a concentrated sugar. One teaspoon contains roughly 6 grams of carbohydrates and 21 calories. If you have diabetes, those small amounts add up across three daily doses. Honey affects blood sugar the same way other sugars do, and being “natural” doesn’t change that. Count the carbohydrates just as you would with any other sweetener.
What to Avoid
Skip processed, pasteurized honey entirely. The heating process destroys enzymes and reduces the antioxidant content that makes honey potentially therapeutic. If the label doesn’t say “raw” or “unpasteurized,” assume it’s been processed. Honey blends that mix real honey with corn syrup or other fillers are also poor choices.
Avoid taking honey with very acidic mixtures like straight lemon juice or apple cider vinegar if your reflux is already active. While these combinations are popular online, adding acid to an already irritated esophagus can make symptoms worse in the short term. Plain honey in warm water is the simplest and safest approach.
