Did you know that within your vast and intricate gut microbiome, there’s a tiny, specialised bacterium playing a monumental role in your overall health? Its name is Oxalobacter formigenes, and although it may not get the attention of more well-known probiotics, its function is both unique and essential.
O. formigenes is a beneficial anaerobic bacterium that naturally resides in the human gut. What makes it so remarkable is its sole purpose: breaking down oxalate, a compound found in many plant-based foods and also produced by the body. This function is especially important because excess oxalate can contribute to the formation of kidney stones, a painful and increasingly common health issue.
But its benefits go beyond kidney health. A diverse and balanced gut microbiome, supported by helpful bacteria like O. formigenes, is a key pillar of overall wellbeing — influencing everything from digestion and immunity to energy and nutrient absorption.
At Dulwich Health, we’ve long believed in the power of nurturing the body’s natural systems. Our commitment to natural, effective health solutions reflects this — and sets the stage for how our products, like OxyTech and AlliTech, can support a thriving gut environment where bacteria like O. formigenes can do their best work.
What is Oxalate and Why Does it Matter?
Â

Â
If you're someone who takes an active interest in your health, you've likely come across the term oxalate — but what exactly is it, and why should it matter to you?
Understanding Oxalate: A Natural Compound With a Catch
Oxalate (or oxalic acid) is a naturally occurring compound found in many of the plant foods we often think of as healthy — including spinach, rhubarb, beetroot, almonds, and even dark chocolate. Your body also produces a small amount of oxalate on its own as part of normal metabolic processes.
While oxalate isn't inherently harmful, problems can arise when levels in the body become too high — a situation known as hyperoxaluria.
When Too Much of a Good Thing Becomes a Problem
One of the most well-documented concerns associated with high oxalate levels is the formation of kidney stones. In particular, calcium oxalate stones — the most common type — form when oxalate binds with calcium in the urine, creating sharp, painful crystals. If you or someone you know has ever had a kidney stone, you’ll know it’s not something you want to experience twice.
This is where the conversation gets interesting — and promising.
Meet Oxalobacter formigenes: A Natural Oxalate Breaker-Downer
Oxalobacter formigenes is a unique type of probiotic bacteria that could play a key role in helping manage oxalate levels. What makes it remarkable is that it feeds exclusively on oxalate — it's the only energy source this bacterium uses to survive and thrive.
By breaking down oxalate in the gut before it has a chance to be absorbed into the bloodstream and passed through the kidneys, O. formigenes can significantly reduce the oxalate load on your body. In other words, it helps stop the problem before it starts — a truly proactive approach to health.
Beyond Kidney Stones: A Growing Area of Interest
While the strongest evidence supports the role of O. formigenes in helping to reduce the risk of kidney stones, emerging research suggests that excessive oxalate might also contribute to other health concerns. Some studies are exploring potential links between high oxalate levels and issues like inflammation, gut irritation, and even reduced bone mineral density.
It's important to stress that these areas are still under scientific investigation, but they highlight why oxalate management is increasingly viewed as a key factor in supporting broader wellbeing — particularly for those aged 35 and over who are thinking ahead about their long-term health.
The Benefits of a Robust Oxalobacter formigenes Population
Â

Â
Once you understand what Oxalobacter formigenes does, it becomes clear why maintaining a healthy population of this unique probiotic could be a game-changer for your health — especially if you’re looking to take proactive, natural steps towards long-term wellbeing.
1. Kidney Stone Prevention: A Natural Line of Defence
The standout benefit of O. formigenes is its ability to help prevent kidney stones, particularly those made from calcium oxalate — the most common type found in the UK and globally. Here's how it works:
Instead of allowing oxalate to be absorbed into the bloodstream — where it ultimately ends up in the kidneys — O. formigenes breaks it down right in the gut. By metabolising oxalate before it reaches the urinary tract, it reduces the overall burden on the kidneys. This means less oxalate excreted in urine, and a lower risk of stone formation.
For those who have experienced kidney stones before — or have a family history of them — encouraging a thriving population of O. formigenes could offer a helpful, natural form of support.
2. Gut Health and Microbiome Balance
While O. formigenes is highly specialised — it survives solely on oxalate — its presence in the gut can still play a positive role in the wider ecosystem of your microbiome.
Your gut microbiome is a vast community of trillions of bacteria, each contributing to digestion, immune response, and nutrient absorption. Even though O. formigenes focuses on a narrow job, its work can reduce metabolic stress and support harmony among other gut bacteria. A diverse and balanced gut microbiome is key to digestive comfort, mental clarity, and immunity — all areas many of our customers actively seek to optimise.
For those struggling with bloating, irregular digestion, or discomfort after eating, this matters. It’s also where OxyTech — Dulwich Health’s trusted oxygen-based colon cleanse — can offer powerful support by creating a gut environment where beneficial microbes like O. formigenes can flourish.
3. Overall Wellness: From Gut to Energy Levels
We often underestimate the gut’s influence on how we feel day to day. But research continues to confirm the link between gut health and overall vitality. When your gut is functioning well — with a healthy microbiome and balanced oxalate levels — your body can:
-
Absorb nutrients more efficiently
-
Regulate energy and mood more consistently
-
Feel lighter and more comfortable after meals
Whether you're planning your next getaway, spending time with family, or enjoying your time in the kitchen, feeling energised and well is essential to making the most of every moment.
By supporting your gut with beneficial bacteria like O. formigenes, you're not just looking after your digestion — you're investing in your long-term wellbeing.
Factors Affecting Oxalobacter formigenes Levels in Your Gut
Â

Â
As with many beneficial gut microbes, the levels of Oxalobacter formigenes in your digestive system can rise or fall depending on several lifestyle, dietary, and environmental factors. Understanding these influences can help you take informed steps to better support your gut health — and by extension, your overall wellbeing.
1. Antibiotic Use: A Double-Edged Sword
While antibiotics are sometimes essential for treating infections, they don’t discriminate between harmful and helpful bacteria. Broad-spectrum antibiotics — especially those commonly prescribed for respiratory or urinary infections — can significantly reduce or even eliminate O. formigenes populations from the gut.
This is particularly concerning because O. formigenes is known to be highly sensitive to many antibiotics, and in some cases, it may not repopulate naturally after treatment. For health-conscious individuals who are already mindful of microbiome balance, this underscores the importance of only using antibiotics when truly necessary — and following up with gut-supportive strategies once a course is complete.
At Dulwich Health, we believe that regaining gut balance post-antibiotic use is a key opportunity to take back control of your health — and it’s where supplements like OxyTech can play a valuable supporting role in resetting your gut environment.
2. Dietary Factors: Food Choices That Influence Your Microbial Allies
Your daily diet has a direct impact on which bacteria thrive in your gut — and O. formigenes is no exception.
Oxalate-Rich Foods
Since O. formigenes uses oxalate as its only energy source, you might assume that eating more oxalate-rich foods (like spinach, almonds, beetroot, or sweet potatoes) is always beneficial. But it’s not quite that simple.
In people with low or absent populations of O. formigenes, a high-oxalate diet can actually backfire — leading to a build-up of oxalate that may increase the risk of kidney stones or other imbalances. The key, as always, lies in moderation and balance. For those with healthy levels of O. formigenes, small amounts of oxalate can help sustain the population. For others, managing intake while supporting gut health more broadly is a better strategy.
Prebiotic-Rich Foods
Unlike probiotics, which introduce new bacteria into your system, prebiotics are fibres that feed the good bacteria already present in your gut. Including a variety of prebiotic-rich foods like leeks, garlic, asparagus, oats, and bananas can help create an internal environment where beneficial microbes — including O. formigenes — are more likely to thrive.
This is especially relevant for cooking enthusiasts who love to create nourishing meals. By incorporating prebiotic ingredients into everyday recipes, you’re not just feeding yourself — you’re supporting your internal ecosystem as well.
3. Lifestyle Habits: More Than Just Diet
While food plays a key role, other lifestyle factors can also influence gut health and the populations of beneficial bacteria such as O. formigenes.
-
Stress: Chronic stress alters gut motility and microbiota composition, often leading to a less diverse and more inflamed gut environment.
-
Sleep: A good night’s rest is essential for gut repair and microbial balance. Poor sleep habits can disrupt circadian rhythms and reduce beneficial bacteria.
-
Exercise: Regular, moderate physical activity has been shown to support gut microbiome diversity and promote overall digestive health.
These may sound like general wellbeing tips — and they are — but they’re also foundational for gut health. And when your gut thrives, your body follows suit.
Supporting Your Gut Microbiome: A Holistic Approach
Â

Â
When it comes to nurturing beneficial bacteria like Oxalobacter formigenes, it’s rarely about a single action — instead, it’s the result of a well-rounded lifestyle. Your gut microbiome thrives when it’s supported on multiple fronts, from food and movement to targeted supplements that enhance the internal environment. Here’s how you can take a proactive, balanced approach.
Dietary Strategies That Nourish the Gut
Eat the Rainbow: Variety is Vital
A balanced, nutrient-rich diet is the bedrock of a healthy microbiome. Aim to eat a wide range of fruits, vegetables, whole grains, legumes, and fermented foods like kefir, sauerkraut, and yoghurt. These supply your gut with essential fibre, plant compounds, and naturally occurring probiotics — all of which help create a thriving, resilient gut environment.
Hydration Matters — Especially for the Kidneys
Drinking enough water each day isn’t just good advice — it’s crucial for kidney health, especially if you’re concerned about oxalate levels. Staying well-hydrated helps dilute the concentration of oxalates in the urine, making kidney stones less likely to form.
Lifestyle Choices That Make a Difference
Your microbiome doesn’t exist in isolation — it responds to your daily habits, too:
-
Manage stress through breathing exercises, mindful walks, or journalling. Chronic stress can negatively impact gut function and microbial balance.
-
Stay active with regular, moderate movement such as walking, swimming, or yoga — proven to support microbial diversity.
-
Prioritise sleep, as restorative rest is vital for both gut repair and immune function.
The Role of Supplements: Where Dulwich Health Can Help
Probiotics: General Gut Support
While Oxalobacter formigenes-specific supplements are still not widely available in the UK, broader multi-strain probiotics can still be incredibly beneficial. These help maintain a diverse microbiome, which in turn creates an internal environment where beneficial bacteria — including specialists like O. formigenes, if present — can survive and thrive.
Think of your gut like a garden: probiotics are like planting seeds, while your diet and lifestyle create the conditions those seeds need to grow.
Where Dulwich Health Comes In
OxyTech: Preparing the Ground for Gut Balance
At Dulwich Health, we understand that beneficial bacteria need the right environment to flourish — which is why we created OxyTech, our oxygen-based colon cleanse supplement.
OxyTech works by introducing oxygen into the colon via magnesium hydroxide, gently releasing oxygen and water as it moves through the digestive tract. This oxygenation helps break down impacted waste and cleanse the gut environment — reducing the risk of harmful bacteria taking hold and supporting a terrain where friendly microbes, like O. formigenes, can thrive.
-
A clean, oxygenated gut may help encourage microbial diversity
-
It can relieve bloating and digestive sluggishness — common complaints among many adults aged 35+
-
And most importantly, it creates the conditions for long-term gut health, which is essential for energy, comfort, and immunity
While OxyTech doesn’t contain O. formigenes, its role is foundational — helping to prepare and maintain the internal environment in which all beneficial bacteria can flourish.
AlliTech: Harnessing the Power of Garlic’s Active Compound
Our other flagship product, AlliTech, works in a different but complementary way. Made from stabilised allicin, the powerful compound derived from garlic, AlliTech acts as a natural antimicrobial, targeting harmful bacteria without disturbing your entire microbiome.
-
Allicin has been shown in research to help regulate microbial balance in the gut
-
This can support the presence of beneficial strains by keeping opportunistic bacteria in check
-
A more balanced microbiome supports digestive comfort, immunity, and nutrient absorption
What’s more, AlliTech’s well-known immune-boosting properties tie directly into the gut-immune axis — the interconnected relationship between your digestive health and immune response. When your gut is healthy and well-populated with friendly bacteria, your immune system is more likely to function at its best.
Who Can Benefit?
Â
Understanding the role of Oxalobacter formigenes and supporting your gut environment isn’t just for those with diagnosed digestive issues. In fact, a wide range of individuals — many of whom are already part of the Dulwich Health community — stand to benefit from taking proactive steps in this area.
✅ Individuals Concerned About Kidney Stone Risk
If you’ve had a kidney stone before, or know they run in your family, supporting a healthy gut environment for O. formigenes could be a smart preventative measure. By breaking down oxalate in the gut before it reaches your kidneys, O. formigenes may help reduce urinary oxalate levels — and with that, the likelihood of future stone formation.
This is especially relevant for men and women in midlife, when kidney stone risk tends to increase, often due to diet, hydration habits, or cumulative health changes.
✅ Anyone Who Has Recently Taken Antibiotics
If you've recently had a course of antibiotics — even for something minor — your gut microbiome may have taken a hit. O. formigenes is particularly sensitive to common antibiotics, and often doesn’t repopulate easily without support. Rebuilding microbial diversity and restoring balance is key to avoiding issues like bloating, irregular digestion, and reduced immunity in the weeks and months following treatment.
✅ People Experiencing Digestive Discomfort
Occasional bloating, sluggish digestion, or irregular bowel movements are more than just annoyances — they may be signs that your gut environment could use some extra care. A clean, oxygen-rich colon — as promoted by OxyTech — not only helps relieve these symptoms but also fosters the right conditions for microbes like O. formigenes to thrive. If you’re looking for a gentle, effective way to reset and refresh your gut, OxyTech is an excellent place to start.
Recap: Why O. formigenes and Gut Health Matter
