Vitamin D Levels May Help Predict Risk Of MS – Forbes
Checking the level of vitamin D in your blood could help identify and assess whether you are at risk of developing MS , according to a new study published online yesterday in the journal, Neurology.
MS, or multiple sclerosis, is a disease which occurs when your body’s immune system attacks myelin , the fatty coating or sheath that covers the nerves in the brain, spinal cord and optic nerves. This can result in weakness, visual problems, loss of balance as well as bladder control, not to mention, chronic pain, numbness and tingling, as well as depression.
The disease has a variable course with some patients experiencing mid symptoms requiring minimal to no medical treatment, while in severe cases, it may lead to paralysis and blindness.
It is well known that there is a relationship between higher levels of sun exposure (sunlight is the most efficient source of Vitamin D) and lower risk of developing MS, as people who live farther from the equator have a higher incidence of MS. It is for this reason that Vitamin D is well regarded as anti- inflammatory, or boosting the immune system .
“There have only been a few small studies suggesting that levels of vitamin D in the blood can predict risk,” said study author Kassandra Munger, ScD, of the Harvard T.H. Chan School of Public Health in Boston. “Our study, involving a large number of women, suggests that correcting vitamin D deficiency in young and middle-age women may reduce their future risk of MS.”
As part of prenatal blood testing, researchers evaluated blood samples from over 800,000 women in Finland. The investigators identified 1,092 women who were diagnosed with MS an average of nine years after giving the blood samples. They were compared to 2,123 women who did not develop MS.
Deficient levels of vitamin D were defined as fewer than 30 nanomoles per liter (nmol/L). Insufficient levels were 30 to 49 nmol/L and adequate levels were 50 nmol/L or higher.
