Thiamin, or vitamin B1, is a water-soluble vitamin found naturally in some foods, added to foods, and sold as a supplement. Thiamin plays a vital role in the growth and function of various cells. Only small amounts are stored in the liver, so a daily intake of thiamin-rich foods is needed.

Although symptoms of thiamin deficiency were first recorded in ancient texts of Chinese medicine, the symptoms were not connected with diet until the late 19th century. In 1884, a Japanese physician noted very high rates of illness and death among Japanese sailors eating a limited diet of only rice for months while at sea. When given a more varied diet with whole grains, meats, beans, and vegetables, rates of illness and death nearly disappeared.

Thiamin is found naturally in meats, fish, and whole grains. It is also added to breads, cereals, and baby formulas.
