Higher levels of vitamin D in the body may reduce the risk of developing the neurological disease multiple sclerosis by as much as 62 per cent, Harvard researchers report. Looking at 257 US military personnel with the disease and 51 healthy controls, the researchers reported that, for every 50-nmol/L (nanomoles per litre) increase in 25-hydroxyvitamin D the associated risk of MS decreased by 41 per cent for white/non-Hispanics.
