Low vitamin D can double the risk of MS
Research by Brent Richards, from McGill University in Montreal, and published August 2015 in PLOS Medicine, analysed the association between genetically reduced vitamin D levels and the likelihood of MS in a pool of 14,498 people with multiple sclerosis and 24,091 healthy controls.
The study found that people with genetically lower vitamin D levels face double the risk of getting MS. Clinical trials are now studying whether increasing vitamin D levels reduces the risk of MS, which is most prevalent in the 20-50 age group.
