Researchers report that a low-dose mixture of zinc, serine, and branch-chain amino acids can alleviate behavioral deficits in three different mouse models of autism. The study shows that when combined together, these three dietary supplements promote communication between neurons in the brain and improve social behaviors. Autism spectrum disorder (ASD) is known to result from abnormal neural development that affects how neurons are connected. Individually, zinc, serine, and branch-chain amino acids are all thought to have positive effects on neural connectivity. The authors hypothesized that a mixture of the three would be a more effective treatment than any individually and...
