Mānuka Honey and Acid Reflux: What the Evidence Actually Shows

Summary: Acid reflux, and its chronic form GERD (Gastroesophageal Reflux Disease), happens when stomach contents flow back into the oesophagus and cause irritation. Early research suggests Mānuka honey may help soothe reflux symptoms when used alongside standard treatment, owing to its thick, coating texture and its anti-inflammatory and antibacterial compounds. The evidence is limited to one small pilot study, so Mānuka honey should be viewed as a possible complement to medical care, not a replacement for it.

If you have ever felt a burning sensation rising from your stomach to your chest, you have experienced reflux. It is one of the most common digestive complaints in the UK, and interest in natural ways to ease it has grown alongside concern about long-term use of acid-suppressing medication. Mānuka honey is often mentioned in that conversation. This guide sets out what the science currently supports, what it does not, and how to approach Mānuka honey sensibly if you want to try it.

What is acid reflux and GERD?

Acid reflux is the general term for stomach contents, including acid, flowing back up into the oesophagus. When this happens frequently or causes damage to the oesophageal lining, it is classified as gastro-oesophageal reflux disease, or GERD. Typical symptoms include heartburn, acid regurgitation, a sour taste, and painful or difficult swallowing. Reflux can also produce less obvious symptoms such as hoarseness, a persistent cough or chest discomfort.

The condition has become more common in developed countries over recent years, and standard treatment usually involves acid-suppressing medication such as proton pump inhibitors (PPIs) or H2 blockers, alongside dietary and lifestyle changes. These medicines are effective at healing the oesophageal lining, but a meaningful number of people continue to experience symptoms despite treatment, which is part of why interest in additional supportive approaches has grown.

Reflux sits within the wider picture of digestive wellbeing. If you are interested in how Mānuka honey relates to the gut more broadly, our guide to Mānuka honey and gut health covers the microbiome side in more detail.

Can Mānuka honey help with acid reflux?

The honest answer is that the evidence is early and limited, but what exists is encouraging. To date, one small clinical study has looked specifically at Mānuka honey in people with GERD. It is important to understand exactly what that study did and did not find, because several sources online overstate the result.

The 2024 GERD pilot study

A pilot study published in 2024 in the journal Food Science & Nutrition (Gośliński and colleagues, Nicolaus Copernicus University, Poland) tested Mānuka honey in 30 patients with persistent reflux symptoms. Participants took a 5 gram dose of Mānuka honey, rated at MGO 400+, three times a day for four weeks, compared with an artificial honey placebo. Crucially, around 80 percent of participants continued their existing reflux medication during the trial, so the honey was tested as an addition to standard care rather than a replacement for it.

After four weeks, the results in the Mānuka group were as follows.

The researchers concluded that Mānuka honey appears to be helpful in GERD when combined with a proper diet and medication, describing the combination as a possible “triple therapy” approach. They were clear that this is a pilot study and that larger trials are needed before firm conclusions can be drawn.

Why the result should be read with care

Several limitations matter for anyone weighing this evidence. The study was small, with only 15 people in each group. It was a pilot, by the authors' own description, intended to justify larger research rather than to prove effectiveness. The honey was supplied free of charge by a honey manufacturer, which the authors declared. And because most participants stayed on their medication, the study shows Mānuka honey may help as an add-on, not that it works on its own. None of this means the finding is worthless. It means Mānuka honey is a promising area of research for reflux, not an established treatment.

Why might Mānuka honey soothe reflux?

Researchers have proposed a few plausible mechanisms, drawn from what is known about honey and about Mānuka specifically.

• A protective coating. Honey is thick and viscous with low surface tension, so it can linger on the lining of the oesophagus and form a soothing physical barrier over irritated tissue.

• Anti-inflammatory action. Mānuka honey contains polyphenols and other bioactive compounds with anti-inflammatory and antioxidant properties, which may support healing of inflamed tissue.

• Antibacterial properties. Mānuka honey is rich in methylglyoxal (MGO), the compound behind its well-documented antibacterial activity. Some laboratory research has examined Mānuka honey against gut bacteria including Helicobacter pylori, which is associated with some upper digestive problems.

These mechanisms are biologically reasonable, but it is worth being precise: they explain why Mānuka honey might help, and they are supported by laboratory and general honey research. They are not the same as large-scale proof in reflux patients.

Which Mānuka honey grade is relevant?

The one clinical study used a honey rated at MGO 400+ (UMF12+). Within the Melora range, that sits at the therapeutic end rather than the everyday end. For people specifically interested in digestive support, the higher-strength options are the natural reference point, while the everyday grades are better suited to general use and cooking. If the grading numbers are unfamiliar, our guides to what MGO means in Mānuka honey and how UMF and MGO compare explain how the strengths are measured.

How to use Mānuka honey for reflux

If you and your GP are comfortable with you trying it, the approach used in the research offers a sensible reference point. In the study, participants took a small amount of honey on an empty stomach in the morning and between meals. A common practical method is to take a teaspoon directly, or to stir it into warm (not boiling) water. Keep the following in mind.

• Treat it as a complement to your existing treatment, not a substitute. Do not stop prescribed medication without medical advice.

• Honey is a sugar. If you have diabetes, are managing your weight, or are watching your sugar intake, factor that in and seek advice.

• Take note of how you feel. Reflux is highly individual, and what soothes one person can be a trigger for another.

• Pair it with the basics that are well evidenced for reflux: avoiding large or late meals, limiting common triggers such as fatty foods, chocolate, coffee and alcohol, and not lying down soon after eating.

Important safety information

Never give honey to infants under one year old. The NHS advises that honey of any kind, including Mānuka, should never be given to babies under 12 months. Honey can occasionally contain bacterial spores that produce toxins in an infant's immature gut, leading to infant botulism, a rare but serious illness. This applies to all honey and is not specific to reflux.

Beyond infants, anyone with a known bee or pollen allergy should avoid Mānuka honey. Reflux that is frequent, severe, or persistent should always be assessed by a doctor, because ongoing acid exposure can damage the oesophagus over time and persistent symptoms occasionally signal conditions that need proper medical management. Mānuka honey is best thought of as a gentle, supportive measure within that wider picture, not as a reason to delay seeking care.
