Autism is a serious problem in the United States, effecting one out of every 68 children.1 With boys having a four to five times greater chance to have autism than girls.
Autism is a behaviorally defined syndrome beginning before three years of age characterized by pervasive deficits in social interaction, impairment in verbal and non-verbal communication, and stereotyped patterns of interests and activities. Currently there is no curative treatment for autism.2
Studies have shown an association between the risk of autism spectrum disorder and vitamin D insufficiency. In this latest study, 109 children with autism spectrum disorder were randomized to receive four months of vitamin D3 supplementation or a placebo (a sugar pill). The group receiving vitamin D3 supplementation saw a significant change in behavior, compared to the placebo group.
This study is the first double-blinded RCT proving the efficacy of vitamin D3 in ASD patients. Depending on the parameters measured in the study, oral vitamin D supplementation may safely improve signs and symptoms of ASD and could be recommended for children with ASD.
