Vitamin D may slow progression of multiple sclerosis

Low vitamin D levels are common in multiple sclerosis, but doctors don’t know how vitamin D may affect the progress of the disorder. In this study, researchers measured vitamin D levels in 465 people with multiple sclerosis taking interferon beta-1b, a drug that suppresses symptom flare-ups.
Beginning with the first sign of symptoms, and continuing for five years, doctors tracked vitamin D levels, symptoms, and health factors.
Compared to those with lower levels, people with adequate vitamin D had a 57 percent lower rate of new brain lesions, a 25 percent lower yearly increase in the size of lesions, and a 57 percent lower relapse rate. Doctors said because vitamin D levels can safely and easily be increased, identifying and correcting vitamin D insufficiency should become part of standard care.
