Scientists Investigate Possible Connection Between Autism and Vitamin D

With autism rates climbing and levels of vitamin D declining because of more sunscreen use and less time spent outdoors, scientists have begun to look into a possible link. A recent study was the first to discover that children with autism had significantly lower levels of vitamin D in their bloodstreams than non-autistic children. Yet many questions remain, and experts say none of the research so far has shown a convincing link.
