The Science Behind LGG® & BB-12® (Learn Hub)

Explore clear, evidence-led summaries of two of the most researched live bacterial strains:

Lacticaseibacillus rhamnosus GG (LGG®) and Bifidobacterium animalis subsp. lactis BB-12®. We translate peer-reviewed probiotic research, clinical trials, and microbiome science into plain English so you can understand what’s been studied—and why it matters day to day. 

What you’ll find here

• LGG® research, in context: studies exploring digestive balance, including use alongside antibiotics and in upset tummies, plus work in early-life settings; many trials are randomised, double-blind and placebo-controlled (the “gold standard”). 

• BB-12® research, in context: studies on gut balance and recovery around antibiotic use, immune/respiratory outcomes, bowel regularity, H. pylori therapy as an adjunct, infant colic, and early oral-microbiome findings. 

*We describe what research has studied and observed. We don’t claim to diagnose, treat, prevent or cure disease, and individual responses vary.
