Summer is here but where is the sun?
Vitamin D deficiency is frequent in Northern Europe as 90% of Vitamin D is synthesized in the skin under the effect of the sun’s ultraviolet irradiation. Low Vitamin D blood levels in childhood and adolescence are a factor in the development of multiple sclerosis in adulthood. In a Finnish study published in March 2016, mothers with inadequate Vitamin D levels in early pregnancy almost doubled the risk of their children developing multiple sclerosis.
