Research suggests that higher vitamin D intake during pregnancy may be associated with cognitive benefits in children, including improved memory and lower risk of certain neurodevelopmental traits. Some studies indicate that high-dose prenatal vitamin D3 supplementation may be particularly beneficial, although experts are urging caution when interpreting the results. The relationship between vitamin D intake and pregnancy outcomes is being explored in various studies, with some findings also suggesting potential links to favourable health outcomes for both mothers and offspring.
