Overview

  • A Danish study led by the University of Queensland analyzed dried blood spots from over 71,000 individuals born between 1981 and 2005.
  • The research confirms that low neonatal vitamin D levels are associated with increased risks of schizophrenia, autism, and ADHD.
  • Findings estimate that 15% of schizophrenia cases, 9% of ADHD cases, and 5% of autism cases could be preventable with adequate neonatal vitamin D levels.
  • The study integrates biomarker and genetic data to strengthen evidence for the causal role of vitamin D in early brain development.
  • The results are prompting reviews of prenatal care guidelines in Australia and fueling discussions on global vitamin D supplementation policies.
