About

Numerous studies have described an altered gut microbiota composition (dysbiosis) in patients with neurodevelopmental disorders that can be correlated with their symptoms, especially gastrointestinal symptoms.

An interventional, randomised, double-blind, placebo-controlled study will be conducted to investigate the effect of a probiotic supplement on the microbiota composition of children aged 3-7 years with neurodevelopmental issues.

The duration of the study will be of 6 months approximately, including 6 months of product intake.

Participants will be randomly assigned to one of the two study groups: control group with placebo administration or probiotic administration group.
