It's a great question! Some MyMSTeam members have reported feeling a bit sharper when taking B12 supplements, though it's worth noting this is largely anecdotal. There's no strong clinical evidence proving B vitamin supplements improve MS symptoms — but that doesn't mean they don't help, it just means studies haven't confirmed it yet.
What is well-established is that B12 deficiency is relatively common in people with MS, and low levels can actually mimic or worsen MS symptoms, such as:
- Numbness or tingling
- Memory or cognition issues
- Weakness or balance problems
- Vision problems If B vitamins are on the radar, there are a few important cautions to keep in mind. High doses of certain B vitamins — including B1, B2, B6, biotin, and folic acid — may actually interfere with disease-modifying therapies (DMTs) by boosting immune activity, which could reduce how well those medications work.
Too much B6 in particular can cause tingling, pain, or numbness — symptoms that could easily be confused with MS activity.
Getting B vitamin levels tested first is a smart move. If a deficiency shows up, supplementing makes a lot of sense. But if levels are already normal, the benefit of adding more is unclear. A neurologist can help figure out what's right for a specific situation.
