Study Links Higher Vitamin D Intake During Pregnancy to Better Child Memory Skills

A recent study published in JAMA Network Open indicates that children whose mothers took higher doses of vitamin D during pregnancy showed modest improvements in memory tests at age 10. The study involved nearly 500 children and compared those whose mothers received 2,400 international units of vitamin D3 daily against those given the standard 400 international units. While the findings suggest potential benefits for specific cognitive skills, there were no significant changes in overall intelligence. Experts caution against self-prescribing high doses of vitamin D, as excessive intake can lead to health issues. Pregnant women should consult healthcare providers regarding vitamin D supplementation.

Key Details: • Study involved nearly 500 children monitored until age 10. • Higher-dose group received 2,400 IU of vitamin D3 daily. • Modest improvements noted in verbal memory and cognitive flexibility. • Consult a healthcare provider before changing vitamin D intake. • Excessive vitamin D can lead to health risks like kidney damage.
