Autism symptoms improve with vitamin D supplementation

New research shows that taking 300 IU vitamin D per kilogram daily for 4 months significantly improves autism symptoms in children 3-10 years old.  A total of 109 children with autism with normal vitamin D levels were randomly assigned to receive vitamin D3 or placebo for 4 months. At the end of the treatment period, Childhood Autism Rating Scale (CARS) scores significantly improved for children in the vitamin D group, with average scores decreasing by about 6.5 points in those receiving vitamin D. The CARS scores evaluated many factors, including emotional response, relating to people, body use, listening response, visual response, imitation, adaptation to change, and general autistic impression.
