What Were We Asked?
We were asked whether probiotics are effective for children with Autistic Spectrum Disorder.
Probiotics are living ‘micro-organisms’ that do not cause disease. They can be used as a food ingredient or taken as a supplement.
No studies could be found that demonstrate probiotics reduce behavioural symptoms of autism.
Until an evidence-base is established and there is more understanding about the effects, we would caution against long-term use of probiotics.
