A new study suggests that three dietary supplements could help reduce behaviors associated with autism in mouse models, offering a potential pathway for future research into therapies for neurodevelopmental conditions. While the findings are preliminary and limited to animal studies, scientists say they provide important insights into how nutritional interventions might influence brain function and behavior.
Researchers tested the effects of three supplements—commonly recognized for their roles in brain health—on mice displaying behaviors analogous to human autism spectrum disorder (ASD). These behaviors included social avoidance, repetitive actions, and heightened anxiety. After a period of supplementation, the mice showed measurable improvements in social interactions and reductions in repetitive behaviors, compared with control groups.
The study highlights the potential for certain nutrients to influence neural pathways related to social behavior and cognitive function. According to the researchers, these supplements may act by modulating neurotransmitter systems, reducing inflammation, or supporting overall neural connectivity in regions of the brain associated with ASD traits.
While the results are promising, experts caution that translating findings from mice to humans is a complex process. Clinical trials in humans will be required to determine whether similar benefits can be achieved safely and effectively in individuals with autism. Researchers also stress that supplements are not a replacement for established therapies, but could one day complement existing treatment approaches.
“This research provides an exciting starting point for exploring nutritional strategies in neurodevelopmental disorders,” said a lead scientist on the study. “Our findings suggest that targeted supplementation may help alleviate certain behavioral challenges, but careful clinical investigation is essential before drawing conclusions for human treatment.”
The study adds to a growing body of research exploring the connection between diet, brain chemistry, and neurodevelopment. Scientists hope that continued investigation will reveal safe, accessible ways to support individuals with ASD and improve quality of life through evidence-based interventions.
