Reducing Your Risk of Multiple Sclerosis (MS)

MS cannot be prevented, but methods are being studied.

Researchers are looking at the role of vitamin D in MS. Some studies have found that people with low vitamin D intake had a higher risk.

People who are worried about their vitamin D level should talk to their doctor. A blood test can check vitamin D levels.

Vitamin D can be found in foods like cod liver oil, salmon, mackerel, sardines, and some milk. The sun also triggers the body to make vitamin D.
