Another Study ..another argument for the usage of Vit D..this time for MS
"What we found was that the higher your vitamin D, the lower your chance of relapse and we found that for each 10 nanomole increase in vitamin D which is a standard measure of concentration of vitamin D in the blood, you can reduce your risk of having an attack of MS by about 10 per cent and therefore doubling your vitamin D will reduce your risk by up to 50 per cent which is really a very, very major result."
