Higher maternal vitamin D helps produce brainier children

Researchers in Spain measured circulating 25-hydroxyvitamin D3 levels in 1820 pregnant women who were mostly in their second trimester of pregnancy and assessed their infants at age 14 months for mental and psychomotor skills.

Infants whose mothers had 25(OH) D3 >30ng/mL were more than 2.5 times
more likely to have higher mental scores and 2.3 times more likely to have higher motor scores than women who had vitamin D deficiency (defined as 25 (OH)D3 <20ng/mL).
