In a recent study, the vitamin D levels of MS patients involved in an assessment of early interferon beta-1b treatment were evaluated. Vitamin D levels were taken before the beginning of the study and then after six, twelve, and twenty-four months. Various outcome measures, including MS relapses and disability were analyzed.
It was found that MS progressed more slowly in participants with higher vitamin D blood levels, and increases in vitamin D levels by 50 nmol/L was linked to a 57 percent reduced risk of developing new active brain lesions as well as 57 percent lower risk of relapse. Furthermore, higher vitamin D levels were associated with 0.41 percent less yearly brain volume loss and a 25 percent reduced yearly increase in T2 lesion volume.
