A major new systematic review has added to the growing evidence that vitamin D may play a key role in the prevention and management of multiple sclerosis (MS). After examining data from 62 scientific studies, researchers found that people with MS generally have significantly lower vitamin D levels than healthy people, and that lower levels are linked to a greater risk of developing the disease and to more severe disability. The review also found that higher-dose vitamin D supplementation may help reduce relapses in some patients. These findings strengthen the case that doctors and patients need to be made more aware of the potential importance of vitamin D and other micronutrients in controlling MS.
