Can Vitamin D Help MS?

Should I Take Supplements?

Experts have different opinions about this. Some say go ahead and take a reasonable amount, since it won't hurt you. But keep it under 10,000 IU a day. Supplements with levels that are too high can be risky.

Other experts say it isn’t worth it, since there's not enough research to prove vitamin D eases symptoms or prevents MS. More important, they say we don't know which dose is best or safest.

So get your doctor's advice before you take vitamin D pills. And don't forget, they’re not a substitute for your regular medicine. You still need your meds to stay healthy and fight your MS symptoms.
