How to take

To help your new microbes settle into their new home it's best to ease them in!

For an adult take 2 capsules of each product per day, for children under 10 years of age we recommend just 1 capsule per day. For those with sensitive digestive systems we recommend you start off on just 1 capsule of each product per day, and then up it to the full 2 capsules of each product per day after two weeks.

We recommend taking them in the morning with breakfast.
Avoid taking them with anything very hot and extreme heat can damage the bacteria! Warm food and drink should be absolutely fine. If you don’t eat breakfast that’s no problem, just take them in the morning anyway. Taking them at the same time every day just helps them and you to settle into the routine!

FAQs

Q. Is this supplement suitable for Children?
A. The live cultures we use have decades of clinical research into their benefits for the health of children. These range from use in pregnant women and breastfeeding mothers straight through to supplementing the children directly as they grow! We recommend that children under the age of 10 receive a half serving of 1 capsule per day. Pregnant/breastfeeding mothers can take a full serving of 2 capsules.

Q. Why do I feel a bit bloated/gassy?
A. When new bacteria enter your gut they let off a little gas as they settle into their new home, this is perfectly normal and is common as you gut microbiome shifts. If you have a little too much gas try cutting the serving to 1 capsule instead of 2 for a couple of weeks.

Q. Why single strain? Is it better than a blend?
A. When you have a blend of different bacteria sometimes these bacteria can compete, reducing effectiveness and sometimes increasing bloating. As well as this when you have a 10BN CFU supplement with 12 strains there isn’t that much of each strain in there! That’s why we went with one strain, backed by solid clinical research, in a high strength formula for a supplement to cut through the noise for precision and clarity.

Q. What are ‘prebiotic fibres’? Why?
A. Prebiotic fibres are plant-based nutrients that your body doesn’t digest, but your gut microbes can use as fuel. By feeding the bacteria already living in your digestive system, prebiotics can help support a balanced gut environment and a healthy, diverse microbiome. We use two gentle, well-studied prebiotic fibres: FOS (fructooligosaccharides) and XOS (xylooligosaccharides), both sourced from plants, to help create the conditions where beneficial bacteria can thrive. Think of it as sending the good bacteria in with a packed lunch!

Q. Will it actually work?
A. The bacteria we use are backed by decades of clinical research that have explored their effects in humans in a wide array of different clinical settings and in the context of various health conditions. Throughout these studies they have shown consistently positive results, that’s why we chose them, meaning you can trust that you’re taking a supplement backed by gold standard scientific research. To learn more about the research and science behind our bacteria check out our Learn section!

Q. What is ‘Delayed Release’?
A. Most supplements just use regular capsules. The problem with this is that they can break down too early, releasing the bacteria into your stomach, where your stomach acid often kills them. We use HPMC capsules, studied and proven to withstand the stomach acid and protect their contents in the process. This ensures that the capsule releases the bacteria in your gut, not your stomach, to ensure that they can get to work where they’re needed most!

Every supplement we create is built on a foundation of strong scientific evidence, from the strength of the strains to the way we combine them.

2 Daily Capsules

Simple once-a-day routine

Our bacterial supplements are crafted to deliver real gut support with a powerful dose of high-CFU live cultures. Each formula is made to introduce a strong community of beneficial bacteria, giving your gut the reinforcements it needs to stay balanced and resilient.

To help those bacteria thrive, we blend in gentle, plant-based prebiotic fibres that act as their natural food source. This pairing encourages better results by creating an environment where the good bacteria can grow, settle, and start making a difference in how you feel. Everything is housed in a delayed-release capsule designed to protect the bacteria as it travels through your digestive system. This smart delivery ensures more of the live cultures reach your gut intact, right where they’re needed most for optimal impact.

Proven Strains

Helps maintain gut health

Our formulations are built around well-researched, plant-based ingredients chosen to work with the gut microbiome. Every component is selected with purpose, backed by published research, and included to serve a clear role in the formula.

To keep things simple and reduce unnecessary variables, every product is vegan, gluten-free, non-GMO, and gelatin-free. We also avoid common fillers, using bamboo-derived silica instead: a plant-based flow agent that helps keep the blend consistent without adding “extras” you don’t need.

By stripping out unnecessary additives and focusing on well-characterised ingredients, we keep our supplements clean, precise, and easy to understand, designed for targeted, everyday gut balance and a consistent routine you can rely on.
