Canadians in general aren't getting enough of the sunshine vitamin.

A recent study conducted by the University of Cambridge showed that increased levels of vitamin D may help repair damage to myelin (the protective layer around nerve endings) in individuals with the autoimmune disease multiple sclerosis (MS). “In people with MS, the immune system attacks their myelin—this does not happen in ‘healthy’ individuals,” explains Samantha Kimball, PhD, MSc, MLT, a research director at Pure North S’Energy Foundation. MS affects about 100,000 Canadians, which is the highest prevalence of the disease in the world. Since many Canadians have low levels of vitamin D due to our long winters, the correlation between low levels and MS isn’t surprising. For vitamin D to impact the myelin, the intake needs to be relatively higher than the recommended daily allowance (600 to 1,000 IUs per day for adult women) and is on average 10,000 IUs per day,” says Kimball. This research is a promising step toward improving MS treatment.
