Vitamin D Testing Can Predict Risk of Multiple Sclerosis in Women

Women with MS were more likely to show vitamin D deficiency

The researchers tried to figure out whether vitamin D deficiency correlated with increased risk of developing multiple sclerosis. They found that 58 percent of women who eventually had multiple sclerosis were also vitamin D deficient. It turns out that many of these women developed the disease at an average of 9 years after they had given blood.

In comparison, only 52% of the women who didn't get multiple sclerosis had vitamin D deficiency. It turns out that there are more women with this vitamin deficiency in the group that eventually developed this neurodegenerative disorder.

Adequate levels of vitamin D seemed to be associated with lower risk of multiple sclerosis

Furthermore, Dr. Mungar's research identified a relationship between normal vitamin D levels and reduced multiple sclerosis risks. Researchers observed that with every 50 nmol/L increase in the vitamin D blood levels, there was a resulting 39 percent decrease in risk.

More severe deficiencies in vitamin D correlated with increased risk of multiple sclerosis

The severity of vitamin D deficiency was related to the level of risk. The study scientists saw that women who had full-blown deficiencies had it worst – with a 43 percent higher risk for getting multiple sclerosis compared to women with normal levels. Compared to women with insufficient levels (30 nmol/L – 50 nmol/L), a full vitamin D deficiency bought these women a 37 percent higher risk.
