Uzimanje dovoljno vitamina D u ranoj životnoj dobi može smanjiti izglede za razvoj multiple skleroze, tvrde britanski istraživači. Multipla skleroza (MS) je češća u dijelovima svijeta daleko od ekvatora, gdje je zimi malo sunčanih sati. Što je veći sezonski manjak sunca, to je teže tijelu nadoknaditi manjak vitamina D. Imajući to u vidu, britanski i kanadski znanstvenici su proučavali varijantu gena koji utrostručuje rizik od multiple skleroze - i našli su da je gen osjetljiv na vitamin D.

"Ako je prisutna premala količina vitamina D, gen ne može funkcionirati ispravno, čineći multiplu sklerozu vjerojatnijom", tvrdi dr. Julian Knight u zborniku radova objavljenim u Centru za ljudsku genetiku sveučilišta Oxford. Knight i kolege sugeriraju da uzimajući nadomjestke vitamina D rano u životu može se smanjiti rizik od MS. Međutim, oni nisu testirali teoriju, koja još čeka potvrdu u praksi. Studija će se pojaviti u PLoS Genetics, "Public Library of Science".
