A new study has linked increased risks of sclerosis with lack of sunshine vitamin – vitamin D. Multiple sclerosis (MS) reduces the ability of some parts of the nervous system to effectively communicate, causing some signs and symptoms of psychiatric, mental and physical problems.

Kassandra Munger, from the US Havard TH Chan School of Public Health, said that there have been little researchers showing that the levels of Vitamin D determine the risk of sclerosis. Munger added that their study involves many women, and shows that normalizing vitamin D deficiency in young and middle- age women may cut down the potential risk of MS.

The research

The scientists used repository samples of blood from over 800,000 women in Finland, taken from prenatal testing. The researchers spotted 1,092 women who had MS about nine years after giving out the blood samples. They compared these women to another 2,123 who didn’t develop the disease.

Vitamin D deficiency was judged as those below 30 nanomoles per liter. Insufficient levels were classified about 30 to 40 nanomoles per liter, and adequate levels were taken to be 50 nanomoles per liter. It was observed that a woman developed MS, about 58 percent experienced deficient vitamin D levels, compared to 52 percent of those who didn’t develop the disease.

The scientists observed that with every 50 nanomoles per liter vitamin D increase in the human body, the possibility of developing multiple sclerosis is lowered by 39 percent. Also, women who showed deficient levels of vitamin D had a 43 percent increased risk of developing sclerosis than those with adequate levels, as well about a 27 percent higher risk than those with insufficient vitamin D levels.

The lead author of the research published in Neurology, Munger said there’s the need for more research on the optimal dose of vitamin D for lowering risk of MS. However, putting efforts to achieve more vitamin D sufficiency will most probably offer much health benefits.
