Deficiencies of vitamin B1 can cause two different conditions that are characterized by nerve damage: beriberi (which causes a burning sensation in the hands and feet) and Wernicke-Korsakoff syndrome (a brain disorder that causes memory problems, leg tremors and problems with coordination). Vitamin B1 supplements can help reverse these conditions and clear up most symptoms. Some research suggests that B1 supplements may also help people who have neuropathy caused by stomach surgery or diabetes.
If you are having symptoms of neuropathy, consult your doctor. Do not take any dietary supplement without your doctor's recommendation.
