Thiamine is found in legumes, fish, lean meats, whole grains and fortified breads and cereals. Deficiency may occur in people who consume large amounts of alcohol.

An extreme thiamine deficiency may result in a brain disorder called Wernicke-Korsakoff syndrome. Thiamine supplementation is safe, thought it is probably not needed for people who eat a healthy, balanced diet.
