At this time, there are no guidelines for the prevention of multiple sclerosis (MS). But there are some medications and supplements being studied. For example, the drug interferon beta may reduce the chance of a relapse or slow the progression of MS.

Researchers are also investigating whether vitamin D has a role in the development of MS. Some studies have found that people with low vitamin D intake had a higher risk of MS. This is an area that is still being studied. If you are concerned about your vitamin D level, talk to your doctor, who can test your blood. Vitamin D can be found in foods like cod liver oil, salmon, mackerel, sardines, and vitamin-D fortified milk. You can also get vitamin D by spending time in natural sunlight, which triggers your body to go through a process to produce the vitamin.
