Lactobacillus Rhamnosus GGUpdated 2 days ago
What is Lactobacillus rhamnosus GG—and why is it in Biotic⁺?
LGG is one of the most widely researched probiotic strains in the world, backed by hundreds of studies spanning over 30 years of scientific research (Capurso et al. 2019). We’ve included it in Biotic⁺ for its well-documented ability to support gut and cognitive health, immune defence, and overall resilience.
🤔 What benefits does LGG offer?
LGG in various lab and human trials has been shown to:
Support digestive balance, including reducing common disruptions like traveller’s tummy or antibiotic-associated diarrhoea
Strengthen the gut barrier, by enhancing tight junctions and mucus protection (Gui et al. 2025)
Supports Cognitive Function, by modulating the gut-brain axis (Sanborn et al. 2020)
Support mental wellbeing, by reducing the stress response (Işık et al. 2025)
Modulate inflammation, promoting calm communication between the gut and brain
🤔 Why this strain—and not just any L. rhamnosus?
LGG is a strain-verified probiotic, identified by its registered patent (ATCC 53103). That means:
It’s been thoroughly tested for purity, safety, and effectiveness
It consistently survives digestion and manufacturing, so it arrives in your gut alive
It’s trusted globally in supplements and clinical settings alike
🤔 How does it work in your body?
LGG supports you by:
Surviving the journey through your digestive system
Binding to your gut lining and reinforcing the gut wall
Blocking harmful microbes from settling in
Supporting both digestive ease, immune readiness and cognitive health
🤔 Why we included LGG in Biotic⁺
This strain brings decades of research, a trusted safety record, and broad-spectrum benefits—from gut comfort to immune strength and cognition. It’s an ideal daily probiotic for helping you stay balanced and resilient.
