Thiamin

Overview

Thiamin (vitamin B-1) helps the body generate energy from nutrients. Also known as thiamine, thiamin is necessary for the growth, development and function of cells.

Most people get enough thiamin from the food they eat. Foods rich in thiamin include yeast, legumes, pork, brown rice, as well as fortified foods, such as breakfast cereals. However, heating foods containing thiamin can reduce thiamin content. Thiamin can also be taken as a supplement, typically orally.

People who have had bariatric surgery, have conditions such as HIV/AIDS, are chronic alcoholics, or use drugs such as the diuretic furosemide (Lasix), are at risk of a thiamin deficiency. Thiamin deficiency can lead to the neurological condition Wernicke-Korsakoff's syndrome or beriberi, a condition that involves peripheral nerve damage.

People also take thiamin to treat inherited metabolic disorders.

The recommended daily amount of thiamin for adult men is 1.2 milligrams and for adult women is 1.1 milligrams.
