MONTREAL, May 11, 2026 /PRNewswire/ - Bio-K+®, a leader in scientifically supported probiotic solutions, announced encouraging findings from an ongoing clinical research initiative exploring the role of gut microbiome in children living with Autism Spectrum Disorder (ASD).
Conducted in collaboration with researchers at the CHU Sainte-Justine Research Centre in Montreal, and supported by the Canadian Institutes of Health Research (CIHR), the work contributes to growing research on the gut-brain axis; the bidirectional connection between the gut microbiome and brain function.

A recent peer-reviewed publication marks a key milestone following nearly six years of collaborative research led by Professor Valérie Marcil, Ph.D., Director and Professor, Department of Nutrition, Faculty of Medicine, Université de Montréal, and Dr. Ghizlane Gaougaou, Ph.D., Research Associate and Study Coordinator.
Initial findings demonstrated that daily consumption of a raspberry-flavored vegan Bio-K+® probiotic drinkable by neurodivergent children was safe and well tolerated. Preliminary observations also suggested potential improvements in gastrointestinal (GI) symptoms, ASD-related behaviors and sleep patterns.
Promising Early Observations
The 30-week feasibility study included a 14-week supplementation period followed by a washout phase. Participants consumed one daily serving of Bio-K+® probiotic.
Key observations included:
A strong safety and tolerability profile, with no adverse events reported
High acceptability and compliance among participants
Preliminary improvements in GI symptoms, behavioral outcomes and sleep patterns
Some observed improvements diminished after discontinuation, suggesting a potential link between ongoing microbiome support and sustained benefits. Parents also reported positive changes in appetite, sleep and overall well-being.
Supported by National Research Efforts
While findings are encouraging, the pilot study was designed to assess feasibility and generate preliminary insights. Larger, placebo-controlled trials are needed to confirm efficacy. With financial support from CIHR and Kerry, a randomized, triple blind, placebo-controlled study was initiated earlier this year. More than 120 children are expected to be enrolled to evaluate the impact of Bio-K+ on behaviors, GI symptoms, brain functions, sleep profile, fecal microbiome and metabolome, and blood chemistry in neurodivergent children.
"These findings contribute to an evolving understanding of the gut-brain connection and highlight the importance of continued research in this area," said Mathieu Millette, Ph.D. Scientific Director of Bio-K+®. "Up to 80% of neurodivergent children diagnosed with ASD experience significant GI challenges, underscoring the importance of exploring the microbiome's role in their quality of life. The emerging evidence around Bio–K+ is promising and may help guide future approaches to supporting these children and their families."
Bio-K+'s Commitment to Science-Driven Innovation
This milestone underscores Bio-K+'s commitment to advancing microbiome science through ongoing clinically grounded innovation and partnerships with globally renowned experts.
Bio-K+ reaffirms its commitment to advancing understanding of the microbiome's role in supporting individuals living with ASD and their families.
