High Vitamin D Levels Among Pregnant Women Protects Them – But Not Their Babies – From MS

A Swedish study involving 164,000 people found that women who had high levels of vitamin D in their blood were 61 percent less likely to develop multiple sclerosis (MS) compared to those who had low levels of vitamin D. However that protective effect did not extend to their babies. Few of the people in the study, who were generally from the northern half of Sweden, had high levels of vitamin D. In fact, only seven of the 192 people who developed MS had high vitamin D levels, compared to 30 of 384 controls without the disease, or eight percent. The researchers found no association between the mothers' vitamin D level and whether their children would later develop MS.
