    Higher-dose vitamin D3 supplementation during pregnancy was linked to modestly higher verbal and visual memory scores in children at age 10.

  • 2

    The study analyzed data from the Copenhagen Prospective Studies on Asthma in Childhood 2010 trial, involving 498 children.

  • 3

    No significant differences were found in estimated intelligence or most cognitive functions between higher-dose and standard-dose groups.

  • 4

    The cognitive analysis was post hoc and not prespecified, with limitations including multiple comparisons and a predominantly White cohort.

  • 5

    Findings suggest that higher prenatal vitamin D levels may have modest effects on memory, but generalizability to diverse populations is limited.
