Vitamin D deficiency during pregnancy may increase risk of MS in children

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. While elevated levels of vitamin D have been associated with a decreased risk of MS in adulthood, some previous research also has suggested that vitamin D exposure in utero may be a risk factor for MS in later life.
