Wellbeing first - the rest will follow

At OptiBac, we work really hard. That’s why we’re the UK & Ireland's most popular* probiotics brand! It’s also because we specialise entirely in live cultures. Live cultures are microorganisms, also known as friendly bacteria, good bacteria or microbiotics.

Our supplements

So, why should you try our live cultures supplements? Firstly, they’re award-winning. This is because they are filled with many of the world’s most researched strains. Secondly, all of our supplements are developed in the world's leading microbiology labs. This gives them their scientific seal of approval. Then there is our wide supplement range. We strongly believe one size does not fit all with friendly bacteria. That’s why we’ve developed 12 different ones - all without colourings, flavours or preservatives.

Backed by science

All live cultures are made up of strains of bacteria, and OptiBac supplements contain strains of the highest quality. Every supplement is scientifically proven to reach the gut alive. Our strains also undergo rigorous testing to make sure they are stable at room temperature. This means you don’t need to keep them in the fridge like other drinks or supplements, so they’re great for on-the-go.


Something for everyone

Within our supplement range, there is good bacteria for everyone. This includes infants, toddlers, pregnant & breastfeeding mothers, vegans, vegetarians, coeliacs and those looking for gluten-free or lactose-free supplement. And as for food allergies? Find out all you need to know in our handy suitability FAQ. Just like people, strains are unique too. We make it our mission to create live cultures no matter your age, circumstance or diet by using different strains to do different things. Each live cultures strain in OptiBac supplements are researched by a team of expert microbiologists. This research includes looking at all the effects of a strain has on the body during specific life stages, so you get friendly bacteria that’s wholly specialised. It’s also why we’re completely transparent. We always list the exact strains in our supplements and not just the microorganism’s family and species.
