Probiotics Designed by Nutritionists

Vegan & dairy free probiotics

These vegan capsules contain no dairy, no allergens and no additives at all. They're just vegan probiotic bacteria, and a chicory prebiotic to help them form thriving colonies.

Gastro-resistant capsules

Most live bacteria products die before reaching your gut. Ours survives, and delivers 36 billion Colony Forming Units (live bacteria) to your intestine.

Immune-boosting Lactospore® Bacillus Coagulans

This patented super-probiotic boosts the immune system and kills off harmful bacteria.

Frequently Asked Questions about Probiotics

Yes, these are fully vegan probiotic bacteria and yeast in a vegan capsule, with NO dairy, NO gluten and NO additives - just the active ingredients.

Both. This probiotic is suitable for one month of treatment to end a bout of diarrhoea more quickly, or to take long-term to help with digestive issues like bloating, gas, constipation or IBS. It helps to promote a balanced and healthy gut microbiome - and can support the immune system and mental health via the gut-brain axis.

Gastro-resistant spores, like Lactospore® (Bacillus Coagulans), are included to ensure the probiotics survive the harsh acidic environment of the stomach and reach the intestines alive, where they can effectively colonise and provide maximum health benefits.

This means the probiotics are protected from stomach acid, which normally kills most bacteria. In the case of probiotics, we want as many bacteria as possible to reach our intestine alive. 

A healthy gut is one with a very wide variety of helpful bacteria. Each strain contributes to different aspects of gut health, from enhancing nutrient absorption to reducing symptoms of digestive discomfort. A probiotic with 14 different strains supports diverse bacterial populations in the gut, helping to maintain a balanced microbiome. 

Saccharomyces Boulardii is a probiotic yeast that helps maintain a healthy balance of gut flora, protects against harmful bacteria, and supports digestive health, particularly during antibiotic use or gastrointestinal disturbances like diarrhoea.

Chicory inulin is a prebiotic fibre that feeds and supports the growth of beneficial bacteria in the gut, enhancing the effectiveness of the probiotics by ensuring they have the necessary nutrients to thrive and multiply.

Chromium supports normal digestion and metabolism by helping regulate blood sugar levels and improving insulin sensitivity, which can increase the benefits of the probiotic bacteria.

Probiotic Live Cultures Ingredients

What's inside

Symbiotic formula

The prebiotic Chicory inulin in the Swallow probiotic formula gives you a symbiotic combination designed to maximise the formation of live probiotic colonies in the gut.

Lactospore® Bacillus Coagulans

This patented super-probiotic can shape-shift into spores, clinically shown to improve digestion, measurably boosts the immune system, and actively kills off disease-causing bacteria.

Lactobacillus Gasseri

It may sound too good to be true, but this little treasure is clinically proven to reduce belly fat by reducing how much fat we absorb from our food. What’s more, it boosts Leptin - the “fullness” hormone, and lowers cholesterol levels.

Lactobacillus Plantarum and Lactobacillus Acidophilus

These powerful probiotics promote a wider variety of beneficial bacteria in the gut by producing bacteriocidins. They’re proven to be effective at tackling bloating, gas and IBS.

Bifidobacterium Longum

This little gem supports mental health by producing gamma-aminobutyric acid (GABA). It also lowers inflammation in the gut.

Saccharomyces Boulardii

This helpful yeast can prevent and treat diarrhea, including holiday tummy and diarrhea caused by antibiotics.

Lactobacillus Reuteri and Lactobacillus Salivarius

These partners are known for improving oral health by killing off harmful bacteria in the mouth. This reduces plaque and gingivitis, making the teeth and gums healthier.

Bifidobacterium Breve

Supports respiratory health by reducing the severity of colds and flu, and improves skin health by reducing inflammation and eczema symptoms.

Chromium

This trace mineral is essential for normal digestion and metabolism of nutrients, and helps the keep the blood sugar balanced - giving a consistent level of energy.

Less bloating

I have been diagnosed with IBS for 10 years and tried just about everything to deal with bloating. I think this probiotic is making a real difference.

B Cleverly, Cambridge

Good results

I always take probiotics for general health and for my skin and I think these are the best. You don't find many with the gastro-resistant capsule. I think that's why I can see the difference in my clearer skin.

More About Probiotic Live Cultures

If you've been through a course of antibiotics, eaten a heavily processed diet for a stretch, or noticed persistent bloating after meals, your gut microbiome may be out of balance. Probiotic Live Cultures was formulated for adults who want a live probiotic that actually reaches the gut alive. It combines 35 billion CFU across multiple bacterial strains, including patented Lactospore® Bacillus coagulans, in a delayed-release capsule designed to survive stomach acid intact.

What Is a Live Probiotic and Why Survival Matters

Your gut microbiome is the population of trillions of bacteria living mainly in your large intestine. These bacteria help break down food, produce short-chain fatty acids that nourish the gut lining, support immune function, and influence everything from digestion to mood. Around 70% of your immune system is located in the gut, where beneficial bacteria interact with the gut barrier and help regulate immune responses.

A live probiotic supplement delivers live, beneficial bacteria to your gut. The catch is that most probiotic bacteria don't survive the journey through your stomach acid. That's why CFU count on the label, while important, isn't the full story. A 100 billion CFU live culture probiotic without protective delivery may deliver fewer live bacteria to your gut than a 35 billion CFU version with a delayed-release capsule. What matters is the live bacteria reaching your colon, not the ones in the bottle.

Why Choose Probiotic Live Cultures from Swallow?

35 Billion CFU, Multi-Strain Formula

Each capsule provides 35 billion CFU across multiple bacterial strains, including Lactobacillus acidophilus, Bifidobacterium lactis, Lactobacillus plantarum, and the patented Lactospore® form of Bacillus coagulans. Different strains do different things. Lactobacillus acidophilus supports the small intestine. Bifidobacterium lactis influences immune function and stool consistency. Bacillus coagulans is a spore-forming strain that's particularly hardy and survives stomach acid even without a protective capsule, which is one of the reasons it's included as a clinically studied strain for digestive support.

Delayed-Release Capsule for Gut Delivery

The capsule is designed not to dissolve in the acidic environment of the stomach. Instead, it stays intact until it reaches the small intestine, where the higher pH triggers it to release the bacteria. This is the difference between most of your live probiotic dose ending up in your gut, versus most of it being destroyed before it gets there. It's also one of the reasons Probiotic Live Cultures don't require refrigeration. The capsule and the spore-forming strains together keep the bacteria stable at room temperature.

CFU Count Guaranteed at End of Expiry

The 35 billion CFU figure is the count at the end of the product's shelf life, not at manufacture. Many probiotic brands print a much higher number on the label that reflects what was in the bottle the day it was made. By the time it reaches you and sits on the shelf for a few months, the count is significantly lower. Swallow's approach is to print what you'll actually be taking on the day you take it. With a live culture probiotic, that distinction matters.

Clean Label, Made in the UK

The formula contains no artificial fillers, no synthetic colours, no added sugars, and no unnecessary bulking agents. Suitable for vegetarians and vegans, free from gluten, dairy, and soy. Manufactured in the UK in GMP-certified facilities.

Key Benefits of Probiotic Live Cultures

A live probiotic works alongside the bacteria already living in your gut, supporting microbial diversity, balance, and the function of the gut barrier. The European Food Safety Authority has not approved health claims specifically for probiotic strains under EU labelling law.

Supporting a Balanced Gut Microbiome

Daily probiotic live culture supplementation has been shown to support microbial diversity, particularly after disruptions like antibiotic use, illness, or dietary change. A balanced microbiome is associated with better digestion, regular bowel habits, and stronger immune resilience.

Supporting Digestion and Reducing Bloating

If you've noticed persistent bloating after meals, irregular bowel habits, or a heaviness in the abdomen that comes and goes, a live probiotic is one of the first places to look. Most customers notice changes in digestion within two to four weeks of consistent daily use.

Supporting the Gut and Immune Connection

Around 70% of the immune system is located in the gut, where beneficial bacteria help regulate immune responses, meaning an imbalanced microbiome can affect how effectively the body responds to infections and inflammation. Supporting your gut bacteria daily is one of the simplest things you can do to support immune resilience, particularly through winter or after illness.

Supporting Gut Health After Antibiotics

Antibiotics save lives, but they also temporarily reduce the population of beneficial bacteria in your gut along with the harmful ones. Many people find their digestion isn't quite right for weeks or months after a course of antibiotics. Taking a live culture probiotic during and after a course of antibiotics can help support the microbiome through the disruption. The recommendation is to take the probiotic at least two hours after the antibiotic dose, to give the beneficial bacteria a chance to establish.

Who Should Consider Probiotic Live Cultures?

Probiotic Live Cultures is suitable for most adults and is particularly worth considering if you:

Notice persistent bloating, irregular bowel habits, or digestive discomfort after meals.

Have recently taken antibiotics and your digestion hasn't quite returned to normal.

Are going through perimenopause or menopause, when falling oestrogen shifts the composition of the gut microbiome.

Travel often, eat at irregular hours, or rely on a busy lifestyle that's hard on your digestion.

Want to support immune resilience, particularly through winter.

Have tried other probiotics without much effect, possibly because the bacteria didn't survive stomach acid or the formula used inactive strains.

Want a clean, vegan, UK-made live probiotic that doesn't require refrigeration.

How to Take Probiotic Live Cultures

Take one capsule daily, ideally first thing in the morning on an empty stomach with a small glass of water. Stomach acid levels are lowest before you eat, which gives the bacteria the best chance of surviving the journey to your gut. If you forget and take it later, it's not a problem. The delayed-release capsule provides protection regardless of when you take it.

If you're taking it alongside a daily multivitamin, space them by 30 to 60 minutes to avoid mineral concentrations interfering with the live probiotic.

Allow at least four weeks of consistent daily use to assess whether the supplement is helping with digestion or bloating. Live culture probiotic effects build gradually.

Caution: speak to your GP before use if you are seriously immunocompromised. Pregnant or breastfeeding women should consult a healthcare professional before starting any new supplement.

Clean, Ethical, and Made in Britain

Swallow supplements are made in the UK in GMP-certified facilities. Probiotic Live Cultures contains only the ingredients listed on the label, with no fillers, no artificial colours, no added sugars, and no synthetic preservatives. Suitable for vegans, free from gluten, dairy, and soy. Packed in 100% recyclable materials with compostable inner packaging.

The Best Live Probiotic, Delivered to Your Door

Gut health affects far more than just digestion. From immunity to mood to skin clarity, the trillions of bacteria living in your gut influence systems throughout your body. A daily live probiotic isn't a quick fix, but it's one of the easiest and most evidence-backed daily habits for supporting your microbiome over months and years.

Probiotic Live Cultures gives you a multi-strain, 35 billion CFU live culture probiotic in a delayed-release capsule, made in the UK. Free UK delivery on every order, fast dispatch from our UK warehouse, and a six-month money-back guarantee on every product.

    Haven’t not any difference but that doesn’t mean my body isn’t thanking me, but like everything you don’t notice small improvements either….? I’m taking with magnesium tablets and I can’t say I’ve had any improvements however life took a rough role so will try again for another few months and update

    Easy to swallow, not much of a after taste, a little more expensive that other brands

    Hi Adrian,

    Thank you for taking the time to share your honest 3-star review of our Advanced Probiotic Live Cultures. We completely understand that it can be difficult to notice improvements when life presents challenging circumstances, and we genuinely appreciate your thoughtful approach to evaluating the supplement's effects.

    You make an excellent point about how our bodies can benefit from probiotics even when we don't immediately notice obvious changes. Probiotic supplements work at a foundational level to support gut health and overall wellness, and these benefits often develop gradually and may not always be immediately apparent, especially during stressful periods when our bodies are managing additional challenges.

    Your plan to continue for another few months is very sensible, as probiotic benefits typically build over time with consistent use, allowing the beneficial bacteria to establish and support your digestive system. We appreciate your commitment to giving the supplement a proper trial period, particularly given the difficult circumstances you've been managing.

    We're pleased to hear that you find the capsules easy to swallow with minimal aftertaste, and we appreciate your honest feedback about the pricing compared to other brands. We focus on providing high-quality, viable live cultures that maintain their potency, which we believe offers good value for the quality delivered.

    Thank you for being a valued customer and for your understanding that probiotic benefits can be subtle and develop gradually over time. We hope that continued use will provide the foundational wellness support you're looking for.
