- Higher maternal vitamin D levels during pregnancy are inversely associated with reduced risk of Autism Spectrum Disorder (ASD) and Attention Deficit Hyperactivity Disorder (ADHD) diagnoses and symptoms in offspring.
- The meta-analysis found a 9% decrease in ASD risk for every 10 nmol/L increase in maternal serum vitamin D levels, with a linear dose-response relationship and no evidence of thresholds.
- There is a suggestion to assess and potentially supplement vitamin D during pregnancy to support fetal brain development and neuroprotection, especially in cases of deficiency.
