According to a recently published article, “Children of mothers with vitamin D deficiency during early pregnancy appeared to be at greater risk for multiple sclerosis (MS) in adulthood, according to an article published online by JAMA Neurology.”

The article continues: “Kassandra L. Munger, Sc.D., of the Harvard T.H. Chan School of Public Health, Boston, and coauthors examined whether serum 25-hydroxyvitamin D (25[OH]D) levels in early pregnancy were associated with the risk of MS in children.”

Furthermore, “The majority of maternal blood samples (70 percent) to measure 25(OH)D levels had been collected during the first trimester and the average maternal vitamin D levels were in the insufficient vitamin D range.” This is crucial information.

Additionally, “The risk of MS as an adult was 90 percent higher in children of mothers who were vitamin-D deficient (25(OH)D levels less than 12.02 ng/mL) compared with the children of mothers who were not vitamin D deficient, according to the results.”

To conclude, “The study concludes that ‘while our results suggest that vitamin D deficiency during pregnancy increases MS risk in the offspring, our study does not provide any information as to whether there is a dose-response effect with increasing levels of 25(OH)D sufficiency. Similar studies in populations with a wider distribution of 25(OH)D are needed.'”
