According to UPI, new research suggests that newborns with low levels of vitamin D may have higher odds of developing multiple sclerosis, or MS, later in life. Vitamin D deficiency is common among the general population, including pregnant women. But the researchers said it's too soon to routinely recommend "sunshine vitamin" supplements for mothers-to-be. Study leader Dr. Nete Munk Nielsen is a researcher at the Statens Serum Institute in Copenhagen, Denmark. Dr. Nielsen said, "The study does not prove that increasing vitamin D levels reduces the risk of MS. Further studies are needed to confirm our results." About 2.5 million people worldwide have MS. It's a chronic disease of the central nervous system characterized by damage to myelin, the fatty substance coating nerve fibers. MS symptoms vary, but can include walking difficulties, fatigue, numbness and vision problems. A growing body of evidence suggests insufficient vitamin D plays a role in MS development. However, the researchers noted that whether prenatal vitamin D levels are a factor remains up for debate.
