Taking Vitamin D Supplements During Pregnancy?

New research from the University of Southampton reveals that taking vitamin D supplements during pregnancy could set children up for a lifetime of stronger, denser bones.

The Findings

In a study involving over 1,000 pregnant women, those who took 1,000 IU of vitamin D daily had children with significantly stronger bone density at ages 4, 6, and 7 compared to those who took a placebo. According to lead researcher Dr. Rebecca Moon, this boost in bone health could lower the risk of osteoporosis and fractures later in life. “This early intervention represents an important public health strategy," said Moon, a clinical lecturer in child health.

The findings, published in The American Journal of Clinical Nutrition, underscore the importance of maternal vitamin D levels.

How Vitamin D Works

Known as the "sunshine vitamin," vitamin D helps regulate calcium and phosphate levels, essential for strong bones, teeth, and muscles. Supplementation during pregnancy appears to influence fetal genes involved in the vitamin D pathway, promoting stronger bones even before birth.

Dr. Moon's previous research suggests that vitamin D supplementation might also reduce the risk of:

• Eczema in children
• C-sections for expectant mothers

A Lifelong Advantage

By ensuring optimal vitamin D levels during pregnancy, women may be giving their children a valuable head start in bone health that lasts a lifetime. For more information: American Pregnancy Association.
