Why BB-12®?

A microbe for seasonal wellness

BB-12® has been around since 1986, with nearly 40 years of research and real-world use behind it. It’s featured in over 300 scientific publications, including more than 100 human clinical-trial papers, the kind of evidence you want when you’re choosing a strain you can feel confident about.
Many of those studies use the double blind placebo control method, widely accepted as the gold standard in scientific studies, which helps keep the findings reliable. We chose BB-12® because a meaningful part of that research looks at it in immune-focused, seasonal settings, including studies involving upper respiratory tract infection contexts. That’s why it’s our pick for seasonal wellbeing, alongside everyday gut balance.

Why Single-Strain Live Cultures?

Single-strain live bacteria supplements keep things clear. With one well-characterised strain at a time, researchers can study it on its own in human trials and understand how it behaves, without the “noise” of multiple strains interacting. That means you can see exactly which strain you’re taking, why it was chosen, and what the published research has explored.

Multi-strain blends can be harder to interpret because different strains may interact or compete, making it less obvious what’s doing what. We prefer a simpler, more transparent approach: one standout strain, selected from the most researched live bacteria in the world, paired with supportive prebiotic fibres and delivered with care. It’s a science-first way to support gut balance and daily wellness with clarity, precision, and scientific backing you can trust.
