Biotin has a proven positive connection to MS
Biotin, a form of vitamin B, is also important in the diet of those who are wishing to fend off the symptoms of their multiple sclerosis. It is a component of enzymes that are capable of breaking down certain substances within the body, which aids in fighting off MS. Biotin is also sometimes referred to as vitamin H. But before you go buy supplements, you may want to look at your preexisting diet. It is very possible that you are already getting enough of the substance, as it is usually consumed via food.
The way in which Biotin has come to be known as a way to fight against MS is as follows, "in spring of 2015, an abstract was published of preliminary results from a clinical trial in France involving 154 people with primary-progressive MS or secondary-progressive MS. They were given high-dose biotin (MD1003) or inactive placebo for 48 weeks. The results suggested that 12.6% of those given MD1003 showed improvement in disability (using either the EDSS scale that measures disability progression, or improvement in a timed walk), versus none of those on placebo, and there were no serious safety issues reported.”
