Is Mānuka Honey Gluten-Free?

Find out if honey fits into your gluten-free diet 

With demand for gluten-free food higher than ever across NZ, more people are taking a closer look at everyday pantry staples, including honey. For individuals with coeliac disease, gluten intolerance, or those exploring a gluten-free lifestyle, clear information about ingredients is important. Knowing exactly what’s in your food is essential to feeling in control and informed.

So, is Mānuka Honey gluten-free? Pure Mānuka Honey does not contain gluten. As a simple, single-ingredient food sourced directly from hives, it has no gluten-containing grains. That said, understanding provenance, processing, and verification is key to making the right choice, especially if you’re prioritising authenticity and quality.

What is gluten and where is it found?

Gluten is a group of proteins found in certain cereal grains. It helps foods maintain structure and elasticity, which is why it’s commonly found in many baked goods and processed foods.

Common gluten-containing foods include:

• Wheat (including spelt and durum)
• Barley
• Rye
• Products made from these grains, such as bread, pasta, cereals, and baked items

Is honey gluten-free?

Mānuka Honey is naturally gluten-free and dairy-free as it's derived from flower nectar. But is all honey gluten-free? Unfortunately, not all honey products are the same. Processed honey may include added ingredients or flavourings, which is why we recommend always checking the ingredient list. The emphasis here is on genuine, single-ingredient Mānuka Honey, with no added flavours, syrups, or additives. 

Single-ingredient honey is gluten-free as nature intended. At Comvita, our single-ingredient Mānuka Honey contains no wheat, barley, or rye, making it gluten-free.

Mānuka Honey contains no wheat, barley, rye, or oats. Honey bees collect nectar from the native Mānuka bush (Leptospermum scoparium) and transform it into honey. Gluten is grain-derived and, therefore, not part of honey’s natural composition.

The role of UMF & MGO, explained

Whether you’re browsing for Mānuka Honey online or in-store, you’ll hopefully see certifications such as UMF™ (Unique Mānuka Factor) and MGO (methylglyoxal) on the label.

UMF™ is an independent grading system used by licensed New Zealand producers. It measures key markers associated with Mānuka Honey and provides a recognised quality rating. MGO measures methylglyoxal, a naturally occurring compound found in Mānuka Honey.

These recognised measures help consumers understand how Mānuka Honey is graded. 

While UMF™ and MGO certifications don’t specifically measure gluten, they do indicate:

• Rigorous testing
• Verified origin
• Strict quality and traceability standards

These grading systems help provide transparency around composition and testing. 

How Mānuka Honey is made (and why it’s gluten-free)

Authentic Mānuka Honey, like ours at Comvita, comes from the remote regions of New Zealand, where bees forage on Mānuka flowers during a short flowering window of around two to six weeks each year. The nectar collected is brought back to the hive, naturally converted into honey, and later harvested by beekeepers.

The process involves:

• Sourcing nectar exclusively from Mānuka blossoms
• Harvesting honey from the hive
• Extracting and filtering the honey to remove natural wax and debris
• Testing and packaging the finished product

Because this process does not involve grains or grain-based ingredients, gluten contamination or exposure is unlikely when the honey remains a single-ingredient product.

So can gluten-free people have honey?

Mānuka Honey is suitable for people looking to avoid gluten, but people with coeliac disease should always follow advice from a healthcare professional.

As with any packaged food, it’s important to carefully check ingredient labels for gluten content. Additives may alter a product's gluten-free status, and gluten-containing ingredients must be clearly stated. Keep in mind that it’s not mandatory to label a naturally occurring gluten-free product as gluten-free.

As always, checking the ingredient list is the best way to be sure. If the ingredient list contains only honey, it is suitable for a gluten-free diet.

Can Mānuka Honey be cross-contaminated with gluten?

Cross-contamination refers to the unintentional transfer of gluten from one food to another, often during processing or packaging. In the case of Mānuka Honey:

• The risk is very low for pure, single-ingredient honey
• Potential risk points include added ingredients in flavoured honey products or shared processing facilities

Choosing high-quality honey, specifically Mānuka Honey, that is carefully handled, tested, traceable and produced transparently, helps minimise this risk.

Will honey cause reflux?

People respond to foods differently. Some may find honey comfortable to consume, while others may experience digestive discomfort depending on personal tolerance. If you are unsure whether it is right for you, it’s best to speak to your doctor.

The bottom line on Mānuka Honey and gluten

Pure, single-ingredient honey with no additives is gluten-free by nature and, therefore, suitable for a gluten-free lifestyle. As with any food, label awareness is important, particularly for flavoured or blended products. Look for honey products with clear origin, transparent testing and trusted certifications, and you can feel reassured that what you consume aligns with your dietary preferences.
