Optimally Formulated Nutraceuticals

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

Immune-boosting Lactospore® Bacillus Coagulans

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

Frequently Asked Questions about Probiotics

"Probiotics" means beneficial bacteria, while "live cultures" means those bacteria are still alive and active when they reach your gut. Many probiotics die in storage or are killed by stomach acid before arriving, so the number on the label often overstates what actually works.

Our Probiotic Live Cultures are built to stay viable. They are guaranteed at 35 billion live CFU to the end of shelf life, not just at manufacture, and held in a delayed-release capsule that survives stomach acid and opens in the gut. That is the difference that matters: live and active where you need them, rather than a big number that has already faded.

Many do not, which is exactly why delivery matters. Standard capsules can break down before they reach the gut, leaving far fewer live bacteria to do their job. Our probiotic live cultures use gastro-resistant capsules designed to survive stomach acid, so more bacteria arrive in the gut where they are actually needed.

Yes. Some people experience a temporary increase in gas or bloating during the first few days or weeks of taking a probiotic. This happens because your gut microbiome is adapting to the new bacteria and is usually mild and short-lived. If symptoms persist beyond 2–4 weeks, become severe, or continue to worsen, the probiotic may not be the right one for you, or your bloating may have another underlying cause that should be investigated.

The best time to take a probiotic is whenever you're most likely to remember it. Consistency is more important than the exact time of day. Many probiotics are best taken with or just before a meal because food can help protect the bacteria from stomach acid, but you should always follow the manufacturer's instructions. If you're using a gastro-resistant probiotic, the capsule is designed to help protect the bacteria as they pass through the stomach.

Some people notice improvements within 1–2 weeks, particularly if constipation is contributing to their bloating. However, most clinical studies assess probiotics after 4–8 weeks, and this is generally how long you should take a probiotic before deciding whether it's working. If you haven't noticed any improvement after around eight weeks of consistent use, it may be worth trying a different strain or investigating another cause of your symptoms.

There isn't one probiotic that's best for everyone because the ideal strain depends on what's causing your bloating. For gas-related bloating, some of the best-studied strains include Lactiplantibacillus plantarum 299v (LP299v), Bifidobacterium longum 35624, Bifidobacterium lactis HN019 and Lacticaseibacillus rhamnosus GG (LGG). A high-quality, gastro-resistant multi-strain probiotic containing clinically studied strains may provide broader digestive support than a product chosen solely for its CFU count.

Yes, probiotics can help with bloating, but only if they're the right probiotic for the underlying cause. The strongest evidence is for bloating associated with IBS, constipation and an imbalance in the gut microbiome. Different probiotic strains have different effects, so choose a product containing clinically studied strains rather than simply the highest number of bacteria. If your bloating is caused by food intolerances, hormonal changes or an underlying medical condition, probiotics alone are unlikely to solve the problem.

Most people need several weeks of daily use before they notice a steady difference, because the bacteria need time to establish in the gut. Some feel changes sooner, but consistency over a few weeks is the realistic expectation.

No. You can keep them in a cupboard at room temperature and they stay stable, which makes them easy to travel with. The delayed-release capsule shields the bacteria from heat and moisture, and the formula includes Bacillus coagulans, a naturally hardy, shelf-stable strain.

If you want to give the more delicate strains the best possible environment, storing the bottle in the fridge helps maintain maximum live counts over time. It is a nice-to-have, not a requirement.

Yes, and it is one of the most sensible times to take a live probiotic. Antibiotics cannot tell beneficial gut bacteria from harmful ones, so a course knocks back your whole microbiome. Take your probiotic at least two hours apart from your antibiotic dose so it is not simply killed off.

Keep taking it for a few weeks after you finish the course to help your gut re-establish, as this is when many people notice their digestion feels off. If you are seriously immunocompromised, check with your GP first.

Yes. They come as a standard-sized, smooth vegan capsule that most people take easily with a glass of water, rather than a large tablet or a gritty powder. You take just one capsule a day, so it is a quick, no-fuss part of your morning.

If you find any capsule tricky, take a mouthful of water first to moisten your throat, then tilt your chin slightly down as you swallow. Do not open the capsule into food, as the shell is designed to stay intact until it reaches your gut.

A daily probiotic of roughly 10 to 50 billion CFU is well supported for general gut health, and ours sits comfortably in that range at 35 billion. A higher number is not automatically better, because a 100 billion CFU product means little if most of those bacteria are dead or destroyed by stomach acid before reaching you.

Two things matter more than a big figure: whether the count is guaranteed to the end of shelf life rather than at manufacture, and whether the bacteria are protected through the stomach. Ours are guaranteed live at 35 billion to end of expiry and delivered in a delayed-release capsule, so the label reflects what actually arrives. Strain variety helps too, which is why this formula uses 15 research-backed strains rather than relying on one.

Less bloating

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.

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.
