Gut health refers to the overall function and balance of the gastrointestinal tract, especially the stomach and intestines.

It involves critical functions such as how well the body digests food, absorbs nutrients, and eliminates waste.

A central and essential part of gut health is the gut microbiome, which is the community of trillions of bacteria, viruses, fungi, and other microorganisms living in the intestines.

These essential living community of trillions of microorganisms are there, keeping us healthy, maintaining our essential connection to our internal health system, and regulating our own moods, thoughts and mental condition via the gut-brain axis.

When these microbes are in balance, they support digestion, help to extract and produce vitamins such as certain B vitamins and vitamin K, they regulate the immune system, protect the gut wall, protect against harmful pathogens, and even influence brain health through the gut–brain connection.

When the gut is out of balance, a condition known as dysbiosis, can lead to problems such as bloating, constipation, diarrhea, acid reflux, or more chronic issues like irritable bowel syndrome, Diverticula disease, certain allergies and worse.

Research also links poor gut health to obesity, type 2 diabetes, autoimmune conditions, and mood disorders, further are more serious issues such as Crohn’s, Colitis, Cancer and Brain degenerating diseases..

Several factors strongly influence gut health. Diet plays a key role, as fiber, prebiotics, and probiotics help maintain a healthy microbiome, while excessive sugar and processed foods can disrupt it. Stress, sleep quality, physical activity, and certain medications, particularly antibiotics, also have major effects.

Gut health is shaped by the microbiome, the trillions of bacteria, yeasts, and other microbes that live in the digestive system.

This community is essential for breaking down food, producing vitamins, regulating the immune system, protecting the gut lining, and even influencing mood and sleep.

A healthy microbiome is diverse and balanced. When it is disrupted, the first signs often appear as low energy, poor sleep, digestive discomfort, and weight changes. Over time, an imbalanced microbiome has been linked with conditions such as irritable bowel syndrome, Crohn’s disease, and colorectal cancer.

Modern diets place enormous strain on gut health. High sugar intake encourages harmful bacterial overgrowth, while ultra-processed foods and low-fibre diets starve beneficial microbes of the nutrients they need. Industrial farming, food additives, and even microplastics contribute further stress. Artificial sweeteners, particularly aspartame, have raised concerns in research showing they can alter the microbiota’s composition and metabolic activity. These changes may impair blood sugar control, increase inflammation, and disrupt the natural balance of the gut.

The impact is not only personal but national. Digestive disorders and diet-related disease account for a major share of NHS spending. The average inpatient hospital bed costs over £1,000 per day, and the treatment of chronic gut-related conditions runs into billions of pounds each year. These costs reflect not just medical treatment but the burden of long-term illness, reduced productivity, and lowered quality of life.

Restoring and supporting the microbiome is therefore essential. Fermented foods and drinks like ROBOT kombucha can play a valuable role. ROBOT kombucha provides live probiotic cultures, organic acids, and natural antioxidants that support a gut-friendly environment. With its unique combination of probiotics, prebiotics from organic honey, and postbiotics from multi-strain fermentation, ROBOT kombucha offers a complete way to nurture microbial diversity, aid digestion, and promote long-term vitality. It is a simple, natural step towards better gut health in a world where modern diets so often undermine it.

Sugar and artificial sweeteners such as aspartame are more than just empty calories or chemical substitutes — they directly influence the gut microbiome, which plays a central role in digestion, immunity, metabolism, and even mood.

Refined sugar fuels the growth of harmful bacteria and yeast in the gut, crowding out the beneficial strains that support balance and resilience. This imbalance, known as dysbiosis, weakens the gut lining, increases inflammation, and can contribute to fatigue, poor digestion, and a weakened immune response. On the other hand, aspartame and other artificial sweeteners disrupt the microbiome in a different way. Studies suggest they reduce microbial diversity and alter the metabolism of gut bacteria, which can lead to glucose intolerance and heightened cravings for sweets. In both cases, the natural ecosystem of the gut is compromised.

That’s why supporting the microbiome with organic, nutrient-dense foods is essential. Organic produce, free from pesticides and synthetic chemicals, provides prebiotic fibers and polyphenols that beneficial bacteria thrive on. But restoring balance often requires more than just removing harmful inputs — it also means actively replenishing the gut with beneficial microbes.

This is where ROBOT Kombucha’s 30-Day Gut Health Programme is so important. Unlike standard probiotic supplements or single-strain ferments, ROBOT Kombucha is brewed with an organic, multi-strain culture of bacteria and yeasts. This diversity mirrors the complexity of a healthy gut, helping to repopulate it with a broad spectrum of beneficial microbes. Because it’s organic, you’re not introducing hidden chemicals or residues that could undermine gut health. Instead, you’re giving your digestive system a living, natural source of probiotics designed to bring it back into balance.

By committing to a structured 30-day reset with ROBOT Kombucha — alongside a diet of clean, organic whole foods — you’re not just undoing the damage caused by sugar and sweeteners. You’re actively rebuilding the foundation of long-term gut resilience, improved digestion, stronger immunity, and overall vitality.

Honey produced from organic farms is critical because its source ~ bees ~ are under increasing threat.

The UK isn’t able to produce a single drop of organic honey made in the UK, due to the fact that pesticides are everywhere.

Since Brexit, the UK has allowed higher levels of pesticide residues on many food items ~ sometimes up to 4,000 times more for certain products ~ significantly weakening safeguards that once mirrored the EU’s standards.

Among the most disturbing changes, residues for neonicotinoids like thiamethoxam and clothianidin have been raised dramatically ~ up to 25 times for some crops ~ even though these chemicals are highly toxic to bees.

Fortunately, there is progress: in January 2025, the UK government rejected an emergency authorization for Cruiser SB ~ a neonicotinoid used on sugar beet marking the first such refusal in five years.

Experts hailed this as a critical victory for pollinators, highlighting that just one teaspoon of that pesticide could kill 1,250,000,000 ! Yup - that’s 1.25 BILLION bees. !

Bees are indispensable to our food system. They are critical for life on earth..

In the UK, pollinators contribute around £690 million annually in crop value ~ that’s approximately £1.8 billion worth of pollination services that would need to be manually replaced if bees disappeared.

In the UK, bees are responsible for more than 70% of all our food pollination - Globally, pollinators like bees support crop production and ensure the reproduction of about 90% of flowering plants.

Without them, food yields would decline, diets would suffer, and the entire ecosystem could unravel.

Organic farming plays a vital role in both preserving bees and nurturing healthy soils. Because it avoids synthetic pesticides, organic farms support biodiversity ~ studies show species abundance in organic fields is, on average, about 30% higher than in conventional systems.

These practices ~ crop rotation, mixed planting, natural fertilisation also foster rich soil microbial communities, which rebuild fertility naturally and support plant health. With over 60% of EU soils and 40% of UK soils already degraded, restoring soil life has become a national priority.

That’s why ROBOT Kombucha heads up the campaign to Save British Bees, and bring back organic honey to the UK!

Beyond soil, organic farming’s ripple effects extend to our health ~ especially our gut microbiome. Agricultural chemicals not only harm pollinators and degrade land, but they may also impact the diversity of microbes that we absorb through food. In contrast, organic produce ~ grown without pesticide residues and teeming with natural microbial life ~ can support a richer and more balanced gut ecosystem, bolstering digestion, immunity, and overall well-being.

In summary, organic honey and organic farming are crucial not just for preserving bees and ecosystem services, but for nurturing healthy soils that in turn sustain a vibrant, diverse gut microbiome. They represent a thoughtful, interlinked path toward ecological restoration and human health.

Kombucha is often celebrated for its probiotics, but the real power of a high-quality, living kombucha comes not just from the microbes themselves, but also from the compounds they create during fermentation. These beneficial byproducts, known as postbiotics, are now understood to be just as important as probiotics for gut and overall health.

Postbiotics include organic acids, peptides, polysaccharides, enzymes, and metabolites that microbes produce while fermenting tea and sugar. Unlike probiotics, which must survive the digestive tract and successfully colonize the gut, postbiotics are already biologically active. They go to work immediately—lowering gut pH to make the environment hostile to harmful pathogens, strengthening the gut barrier, and signaling directly to the immune system. Research has shown that postbiotics can reduce inflammation, improve nutrient absorption, and even modulate communication along the gut-brain axis.

This is where ROBOT Kombucha is unique. Because it is brewed with a complex multi-strain culture—13 diverse bacterial strains and 4 complementary yeast strains—its fermentation process creates a broader and more potent postbiotic profile than standard kombucha. The bacterial strains, including Bacillus subtilis, Paenibacillus taichungensis, and Gluconacetobacter rhaeticus, generate short-chain fatty acids, antioxidants, and antimicrobial compounds that support gut balance and resilience. Meanwhile, yeast strains like Saccharomyces cerevisiae and Brettanomyces bruxellensis contribute B vitamins, amino acids, and bioactive metabolites that nourish both the microbiome and the body.

The combination of probiotics and postbiotics makes ROBOT Kombucha more than just a fermented drink—it is a dynamic gut health solution. While the living microbes help restore microbial diversity, the postbiotics deliver immediate functional benefits, helping to calm inflammation, repair the intestinal lining, and strengthen the immune system. Together, they create a one-two effect: reseeding the gut while also creating the optimal environment for long-term microbial balance.

In a world where sugar, processed foods, and chemical residues disrupt gut health daily, a structured programme with ROBOT Kombucha offers a rare opportunity to replenish, reset, and restore. Its unique organic, multi-strain, postbiotic-rich formulation ensures that every sip supports both the living ecosystem within and the bioactive environment that protects it.

ROBOT Kombucha, is the only commercially available ‘Multi-strain’ Kombucha in the world.

Single-strain vs multi-strain kombucha:

Single-strain = one dominant culture (often a single added Lactobacillus or yeast).

It can ferment, but metabolic range is narrow, so flavour/acid profile and resilience are limited.

Multi-strain (13 different strains of complex gut bacteria cultures, well-chosen SCOBYs) = mixed acetic-acid bacteria (AAB), lactic-acid bacteria (LAB), and yeasts working together.

This gives a much broader metabolism (acids, esters, gluconates), more consistent pH drop, and richer flavour/antioxidant chemistry.

Reviews and surveys of commercial kombuchas repeatedly show clear consortia in authentic hand-made organic multi-strain kombucha rather than one single strain. 

Why multi-strain is better;

Fermentation performance & flavour: different microbes specialise (sugar uptake; acetic vs lactic acid; ester formation), so multi-strain ferments are typically more robust and complex, and can withstand pasteurisation.

Process resilience: diversity can buffer against temperature/pH swings and raw-material variation ~ useful in real-world production.

(Seen across kombucha microbiome studies and synthetic-community experiments.) 

Pasteurisation, shelf life, and what’s actually true, is that most other commercial Kombuchas are single strain, and therefore do not withstand pasteurisation.

ROBOT is exceptional organic multi-Kombucha strains which deliver powerful postbiotic technology.

Pasteurisation increases shelf-life primarily by stopping living microbes (so no re-fermentation, alcohol drift, or haze).

That’s why many ambient (room-temp) kombuchas are pasteurised or micro-filtered.

However, A multi-strain culture does not inherently “withstand pasteurisation”; heat that’s sufficient to stabilise the drink will not affect to multi-strain kombucha microbes, multi-strain.

Single strain brands that want both stability and living cells typically:
1. keep the product refrigerated, or
2. add heat-tolerant/protected probiotic strains after a kill-step (e.g., microencapsulated adjuncts) and validate survival to end-of-life. (This is an emerging practice discussed in recent kombucha R&D literature.) 
3 Shelf life of raw (unpasteurised) kombucha is governed by pH (≈2.5–4.2), yeast growth, and alcohol drift; keeping it cold slows those changes. 

Bottom line: pasteurisation gives longer shelf life because it kills pathogens, however the Kombucha culture being multi-strain changes that.

ROBOT Kombucha achieves exceptional long life with multi-strain but also delivers powerful “postbiotic” benefits (metabolites, acids, polyphenol transformations) rather than live CFUs, this is very credible.

ROBOT is the only commercially available multi-strain kombucha in the world.

Published surveys find few commercial kombuchas which contain multiple bacterial/yeast taxa (though the exact species/strains vary widely by brand and batch).

ROBOT Kombucha uses a deliberately curated, multi-strain culture (not a single added strain) engineered for complex flavour and proven gut healing process and consistency.

Prebiotics, probiotics, and postbiotics are three interconnected pillars of gut health, but they work in different ways. Understanding how they interact helps explain why a truly functional product like ROBOT Kombucha—with its unique postbiotic blend—is so effective.

Prebiotics are non-digestible fibers and natural compounds found in foods like garlic, onions, bananas, and whole grains. Unlike regular carbohydrates, prebiotics are not broken down by our digestive enzymes; instead, they serve as food for beneficial bacteria in the gut. By selectively feeding the right microbes, prebiotics encourage a healthier microbial balance, increasing the abundance of strains that produce protective metabolites such as short-chain fatty acids. Without prebiotics, probiotic microbes cannot thrive or colonize effectively.

Probiotics are live microorganisms—often bacteria or yeast—that, when consumed in adequate amounts, provide health benefits to the host. They can help restore microbial diversity disrupted by antibiotics, stress, or poor diet, and they compete with harmful microbes for space and resources in the gut. High-quality probiotics support digestion, nutrient absorption, immune function, and even mood regulation. The challenge is that not all probiotics survive stomach acid or make it to the intestines intact. That’s why multi-strain, resilient formulations are essential.

Postbiotics are the bioactive compounds produced by probiotic microbes during fermentation. These include organic acids, antimicrobial peptides, polysaccharides, enzymes, and antioxidants. Unlike probiotics, postbiotics are not alive—yet they provide immediate benefits without needing to colonize the gut. They strengthen the intestinal barrier, reduce inflammation, modulate immune responses, and make the gut environment less hospitable to pathogens.

This is where ROBOT Kombucha stands out. Its organic, multi-strain culture of 13 bacteria and 4 yeast strains doesn’t just deliver probiotics—it generates a wide spectrum of postbiotics during fermentation. These compounds survive pasteurisation, travel through the digestive system intact, and act directly on gut health from the moment they are consumed. By combining probiotics to reseed the microbiome with postbiotics to regulate and protect the gut environment, ROBOT provides a dual-action approach that most probiotic supplements cannot.

In short, prebiotics feed, probiotics seed, and postbiotics heal. Together they form the foundation of a resilient microbiome. ROBOT’s unique strength lies in its rich postbiotic profile, which amplifies and sustains the benefits of its multi-strain live cultures—making it a truly complete gut health solution.

Organic is more than just a label—it is a system of farming and food production designed to work with nature rather than against it. At its heart, organic means avoiding synthetic pesticides, herbicides, and fertilizers, and instead focusing on soil health, biodiversity, and ecological balance. For consumers, it guarantees food and drink produced without genetically modified organisms (GMOs), artificial additives, or residues that can compromise human health and the environment.

From a farming perspective, organic methods are essential because they restore and preserve soil fertility. Instead of relying on chemical fertilizers, organic farmers build soil health through crop rotation, composting, cover cropping, and natural fertilisers. This promotes rich microbial life within the soil—microorganisms that recycle nutrients, support plant resilience, and increase carbon sequestration. Healthy soils not only grow more nutritious crops but also act as carbon sinks, playing a vital role in addressing climate change. With over 40% of UK soils degraded and global agriculture responsible for nearly a quarter of greenhouse gas emissions, organic farming represents one of the most effective tools we have for protecting both food security and the climate.

For human health, organic standards matter because what we eat directly influences our microbiome. Conventional farming often leaves behind pesticide residues and depletes the natural microbial diversity of food, which in turn affects our gut ecosystem. Organic crops, by contrast, are grown in living soils that foster microbial richness. When we consume organic food and beverages, we are supporting our own gut microbial diversity—a critical factor in digestion, immunity, and even mental health.

The EU Organic Standards and the British Soil Association play a vital role in guaranteeing this integrity. The EU standards are among the strictest in the world, requiring farms to follow rules on biodiversity, soil protection, and animal welfare. The Soil Association goes even further, setting higher benchmarks for pesticide use, food processing, and transparency. Products certified by these bodies must undergo rigorous audits to ensure every stage of production is truly organic.

For ROBOT Kombucha, displaying these symbols on the can is more than a certification—it is a mark of trust. It tells the consumer that the kombucha they are drinking is not only brewed with integrity but also contributes to a healthier planet. By adhering to these standards, ROBOT ensures that its multi-strain, probiotic and postbiotic-rich kombucha is free from hidden chemicals, grown in harmony with nature, and fully aligned with the principles of soil, gut, and planetary health.

B-Corp, short for Benefit Corporation certification, is an internationally recognised standard for businesses that balance profit with purpose. Unlike traditional companies, which are judged primarily on financial performance, B-Corp certified businesses are assessed on their entire social and environmental impact. Certification is managed by the non-profit organisation B Lab, which measures companies against rigorous criteria across governance, workers, community, environment, and customer accountability.

To achieve B-Corp status, a company must demonstrate transparency, legal accountability, and a measurable positive impact on people and the planet. This involves everything from how a business treats its employees, to how it sources its materials, manages its supply chain, and reduces its carbon footprint. Companies are scored on a 200-point scale, and must achieve at least 80 points to be certified—a threshold that requires genuine commitment rather than surface-level changes.

The importance of B-Corp lies in trust and accountability. In a market where greenwashing and vague ethical claims are common, the B-Corp mark reassures consumers that a company is truly walking the talk. It signals that a business is not just minimising harm but actively working to create positive outcomes—whether by supporting regenerative agriculture, ensuring fair wages, or reducing environmental impact. B-Corps are also legally bound to consider stakeholders as well as shareholders, making sustainability and ethics part of their DNA rather than optional extras.

For a health-focused brand like ROBOT Kombucha, becoming or working towards B-Corp certification is a natural extension of its ethos. Kombucha is about gut health, but ROBOT’s mission extends further: to support healthy soils, thriving ecosystems, fair supply chains, and resilient communities.

The B-Corp certification embodies this holistic vision. Displaying the B-Corp logo alongside organic certifications would show consumers that ROBOT isn’t just a drink—it’s part of a global movement to redefine success in business, proving that companies can be both profitable and regenerative..

BPA, or Bisphenol A, is a synthetic chemical widely used in the production of plastics and resins, particularly in food and drink packaging such as water bottles, plastic containers, and the inner linings of cans. For decades it was valued for its durability and resistance to corrosion, but growing evidence has revealed its significant risks to human health.

BPA is classified as an endocrine disruptor—a chemical that mimics or interferes with the body’s natural hormones. Because its structure is similar to estrogen, BPA can bind to hormone receptors, disrupting normal signaling pathways.

This interference has been linked to reproductive disorders, altered development in children, thyroid dysfunction, metabolic problems such as obesity and insulin resistance, and an increased risk of certain cancers. Even at low levels of exposure, BPA can accumulate in the body and trigger subtle but long-lasting health effects, particularly during vulnerable life stages such as pregnancy and early childhood.

For gut health, BPA may also contribute to inflammation and dysbiosis by disrupting the delicate microbial ecosystem in the intestines.

Research suggests it can alter the composition of the gut microbiota, reduce microbial diversity, and compromise the integrity of the intestinal barrier—further linking it to metabolic and immune-related disorders.

This is why it is critical that ROBOT has taken the decision to ban BPA from all its cans. By ensuring every can is BPA-free, ROBOT protects its consumers from exposure to harmful endocrine-disrupting chemicals while safeguarding the integrity of its organic, probiotic and postbiotic-rich kombucha. The commitment goes beyond compliance ~ it is a deliberate choice to prioritise health, transparency, and trust.

For a brand dedicated to gut and systemic well-being, packaging matters just as much as what goes inside the can. By eliminating BPA, ROBOT aligns its product with its values: nourishing the body without compromise and protecting future generations from hidden chemical risks.

Glass bottles are often perceived as the “greener” option for drinks, but when we look closely at the science of energy use, transport emissions, and recycling efficiency, the argument for glass falls apart. ROBOT Kombucha made the conscious choice to use cans, not bottles, because they are far more sustainable and better aligned with the brand’s mission to protect gut health, people, and the planet.

Glass production is extremely energy-intensive. To make new bottles, raw materials such as sand, soda ash, and limestone must be melted at temperatures over 1,500°C, a process that consumes vast amounts of fossil fuel energy. Recycling glass is also inefficient: while it can technically be recycled endlessly, in practice the system is far from closed. Glass loses quality during the recycling process, and most recycled glass is “downcycled” into aggregate for roads rather than being made back into bottles. Transport adds another layer of harm—glass is heavy and fragile, meaning it requires more energy to ship, more packaging to protect it, and creates higher CO₂ emissions throughout the supply chain.

Aluminium cans, by contrast, are lighter, stronger, and far more circular. Cans are infinitely recyclable without loss of quality, and in countries with effective recycling systems, an aluminium can is often back on the shelf as a new can within 60 days. Recycling aluminium saves up to 95% of the energy required to make it from raw materials. Because cans are so lightweight, transport emissions are drastically lower, making them a far more climate-friendly option than glass.

For ROBOT Kombucha, cans also ensure product integrity. Kombucha is a living, fermented drink that can continue producing natural carbonation. Cans are airtight, lightproof, and robust, protecting the live cultures and postbiotic compounds without the risk of UV damage or spoilage that can occur in glass.

ROBOT is also pioneering a deposit return scheme for cans, ensuring consumers are incentivised to recycle and that aluminium stays within the circular economy. This system dramatically reduces waste leakage into the environment, tackling pollution at the source while keeping the carbon footprint as low as possible.

By choosing cans, ROBOT Kombucha rejects outdated perceptions and embraces a future-proof packaging model. It is not only about gut health in a can, but also about protecting planetary health—through reduced emissions, true recyclability, and leadership in circular packaging systems.

ROBOT Kombucha has a shelf life of 18 months, which is significantly longer than many conventional kombuchas. This longevity is not achieved through artificial preservatives or pasteurisation, but through the strength and resilience of ROBOT’s unique multi-strain, postbiotic-rich formula.

Whereas many kombuchas rely on a limited range of microbes that degrade quickly or lose potency after bottling, ROBOT is brewed with 13 diverse bacterial strains and 4 complementary yeast strains.

This microbial complexity ensures a robust fermentation process that produces a wide spectrum of postbiotics—the bioactive compounds created by probiotics during fermentation. These include organic acids, enzymes, peptides, and antioxidants that remain stable and functional long after the live microbes themselves have done their work.

It took years of research and refinement to develop the postbiotic formula that defines ROBOT Kombucha. The goal was not just to create a drink that survives canning and storage, but one that continues to deliver genuine health benefits well beyond the shelf life itself. The result is a kombucha that protects and strengthens the gut in three distinct ways: probiotics reseed the microbiome, postbiotics actively regulate inflammation and immunity, and organic acids preserve the drink naturally, ensuring stability for 18 months without compromising health integrity.

Even after the kombucha has been canned, the postbiotic profile remains active. This means that the compounds responsible for strengthening the gut barrier, supporting digestion, modulating the immune system, and creating a hostile environment for pathogens are still present and effective at the time of drinking—whether that is on day one or at the very end of the shelf life. Importantly, postbiotics continue to function in the gut even after digestion, supporting systemic health and reinforcing the gut-brain axis.

For consumers, this means ROBOT Kombucha is not just shelf-stable—it is health-stable. Every can delivers the same critical benefits throughout its 18-month life, ensuring consistency, reliability, and trust in a category where health claims are often fleeting.
