Summary

This study tests whether a probiotic called Lactobacillus plantarum can improve social interactions, reduce inflammation, and enhance quality of life in adults with autism spectrum disorder. Twelve participants take the probiotic for 8 weeks, with assessments including blood tests, gait analysis, and caregiver questionnaires. The goal is to explore links between gut health, immune function, and autism symptoms.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
a probiotic supplement called Lactobacillus plantarum, containing 60 billion CFU per day
What this could lead to
If it works, this could point toward a gut-based approach to easing some autism-related symptoms in adults.
What could go wrong
This is a very small, early-stage trial with only 12 participants, so results may not apply widely. Probiotics can sometimes cause digestive discomfort.
