The human gut is often referred to as the body’s second brain, and for good reason. A balanced gut microbiome is essential for digestion, nutrient absorption, immune function, and even mental wellbeing. In recent years, natural remedies have gained popularity for supporting digestive health, and Mānuka honey has stood out due to its unique bioactive properties. But does the science support its use for gut health?
This detailed guide explores how Mānuka honey may contribute to a healthier gut, which types to consider and how to use it safely.
What Is Mānuka Honey?
Mānuka honey is a monofloral honey produced in New Zealand and parts of Australia from the nectar of the Mānuka bush (Leptospermum scoparium). It is known for its distinctive flavour, thick texture, and most importantly, its powerful antibacterial and anti-inflammatory properties.
Unlike regular honey, Mānuka honey contains a naturally occurring compound called methylglyoxal (MGO), which is responsible for much of its unique antimicrobial activity. The potency of Mānuka honey is measured using the UMF® (Unique Mānuka Factor) grading system, which accounts for MGO levels along with other quality markers.
Why Gut Health Matters
Your gut is home to trillions of microorganisms that form the gut microbiota. These microbes are involved in:
-
Digesting and breaking down food
-
Producing essential vitamins (like B12 and K)
-
Regulating immune responses
-
Communicating with the central nervous system via the gut-brain axis
An imbalance in this ecosystem, known as dysbiosis, can lead to bloating, constipation, diarrhoea, and chronic issues like irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and even anxiety.
Maintaining gut health involves supporting microbial diversity, reducing inflammation, and avoiding harmful bacteria, areas where Mānuka honey may have a beneficial role.
The Potential Gut Health Benefits of Mānuka Honey
1. Antimicrobial Properties Against Harmful Gut Bacteria
In clinical studies, Mānuka honey has been shown to inhibit the growth of several pathogenic bacteria commonly linked to gut disorders. In laboratory studies, it has demonstrated effectiveness against:
-
Clostridium difficile: A bacterium associated with antibiotic-induced diarrhoea and colitis.
-
Helicobacter pylori: Linked to gastric ulcers and some cases of stomach cancer.
-
Escherichia coli (E. coli): Certain strains can cause intestinal infections and inflammation.
The antimicrobial effect is largely attributed to MGO, which works by damaging bacterial cell walls and interfering with their replication.
While Mānuka honey is not a replacement for medical treatment, it may support microbial balance by reducing the burden of harmful bacteria in the gut.
2. Soothing Inflammation in the Digestive Tract
Gut inflammation plays a role in conditions such as IBS and IBD. Research suggests Mānuka honey can reduce inflammation markers due to its antioxidant and anti-inflammatory properties. Animal studies have demonstrated that Mānuka honey may help reduce intestinal inflammation and oxidative stress when taken orally.
This is promising for individuals dealing with chronic bloating, discomfort, or gut lining irritation. Its soothing properties may calm digestive discomfort when consumed regularly in appropriate amounts.
3. Supporting Ulcer Healing
Helicobacter pylori infections are a leading cause of peptic ulcers. Some in vitro studies suggest that Mānuka honey can inhibit this bacterium’s activity, potentially supporting the healing process when used alongside conventional treatments.
In one study published in the Journal of the Royal Society of Medicine, Mānuka honey was found to reduce the viability of H. pylori in vitro. Although more human studies are needed, the findings point toward its potential as a supportive remedy in gastrointestinal ulcer management.
4. Prebiotic-Like Effects
Some types of honey, including Mānuka, contain oligosaccharides that may function as prebiotics, compounds that feed beneficial gut bacteria. While the prebiotic potential of Mānuka honey requires further clinical validation, early evidence suggests it may help support the growth of Lactobacillus and Bifidobacterium, which are essential for a healthy gut ecosystem.
Supporting these friendly bacteria helps maintain digestive balance, promote regular bowel movements, and strengthen the immune system.
How to Use Mānuka Honey for Gut Health
1. Choose the Right UMF Rating
For digestive support, a UMF® rating of 10+ or higher is generally recommended. Melora offers a range of certified Mānuka honeys that are independently tested for MGO content and purity.
2. Start With 1–2 Teaspoons Daily
Consume it on an empty stomach in the morning, or add to a warm (not hot) herbal tea. Avoid exposing Mānuka honey to high heat, as this can degrade its beneficial compounds.
3. Combine With Other Gut-Supportive Foods
Pairing Mānuka honey with probiotic-rich yoghurt, kefir, or fermented foods may help boost overall gut health. You can also drizzle it on oats or blend it into smoothies for a balanced breakfast.
4. Use It Consistently
Gut healing takes time. For best results, Mānuka honey should be consumed daily over a period of weeks, with attention paid to diet, hydration, and stress management.
Is Mānuka Honey Safe for Everyone?
While Mānuka honey is safe for most adults, there are a few considerations:
-
Diabetics: Due to its natural sugar content, those with diabetes should monitor their blood sugar levels and consult a healthcare professional before regular use.
-
Children Under 12 Months: Honey should never be given to infants under one year due to the risk of infant botulism.
-
Allergies: People with allergies to bee products should exercise caution and seek advice before trying Mānuka honey.
Melora’s Mānuka honey is traceable from hive to jar, and every batch is tested for quality, purity, and authenticity, providing added assurance for those with health concerns.
