The Consortium of Multiple Sclerosis Centres (CMSC) has recently held a webinar of experts discussing the role of vitamin D in MS.
The discussion was between Dr Emmanuelle Waubant, Professor of Clinical Neurology and Paediatrics at the University of California, San Francisco, and Dr Ellen Mowry, Associate Professor of Neurology and Epidemiology at Johns Hopkins University in Baltimore, moderated by June Halper, the Chief Executive Officer of CMSC.
It was interesting to note that while the experts concurred that data were not conclusive, with the inevitable caveat that more research is required, specifically randomized controlled trials of vitamin D in people with MS, Prof Waubant was very clear that he routinely checks vitamin D at diagnosis and mostly finds that it is low.
He also regularly prescribes vitamin D in doses of 2,000-4,000IU of vitamin D3 daily, but is prepared to increase it after checking the blood level at three months.
The experts also concluded that supplementation should not be stopped in summer, and noted that pregnant women need 50-100% more than this dosage.
While these doses are a little lower than we recommend at OMS, it is important to note the shift in mainstream neurology towards vitamin D supplementation for most people with MS.
