CHOLINE: 129 participants already taking Rebif (beta interferon 1a) and with low blood levels of vitamin D were recruited at 27 MS clinics in France. They were randomly assigned to take either 100,000 IU vitamin D3 (equivalent to about 7,000 IU/day) or placebo, once a fortnight for just under two years. The main measure of the study was a change in the number of relapses.
