MS can't be prevented, but methods are being studied. The drug interferon beta may lower the chance of a relapse or slow MS from getting worse.
Researchers are also looking at whether vitamin D has a role in MS. Some studies have found that people with low vitamin D intake had a higher risk. This is still being studied. If you are worried about your vitamin D level, talk to your doctor. Your blood can be tested. Vitamin D can be found in foods like cod liver oil, salmon, mackerel, sardines, and some milk. You can also get it from the sun. It triggers your body to make it.
