In a study published online Jan. 20 2014, in JAMA Neurology it was found that Vitamin D may slow the progression of multiple sclerosis (MS) and also reduce harmful brain activity.
And correcting vitamin D deficiency early in the course of MS is important, according to the report.
Previous researchers in several studies have noted that there is a striking correlation between geographic location (and sunshine levels) and MS levels (notably Esparza ML, Sasaki S, Kesteloot H. Nutrition, latitude, and multiple sclerosis mortality: an ecologic study. Am J Epidemiol 1995; 142:733-737). Fish consumption (positive) and saturated fat consumption (negative) also play roles.
As long ago as 1986 in a small study involving just 16 patients, those given vitamin D were 2.7 times less likely to relapse. (Goldberg et al).
