Sixteen percent of 25 people with multiple sclerosis (MS) given an average of 14,000 international units (IU) of vitamin D a day for a year suffered relapses, says Jodie Burton, MD, a neurologist at the University of Toronto. In contrast, close to 40% of 24 MS patients who took an average of 1,000 IU a day -- the amount recommended by many MS specialists -- relapsed, she says.
Also, people taking high-dose vitamin D suffered 41% fewer relapses than the year before the study began, compared with 17% of those taking typical doses.
People taking high doses of vitamin D did not suffer any significant side effects, Burton tells WebMD."
