Sources of Vitamin B1

Whole grain cereals, legumes (e.g., beans and lentils), nuts, lean pork, and yeast are rich sources of vitamin B1 (thiamin) (2).

Because most of the thiamin is lost during the production of white flour and polished (milled) rice, white rice and foods made from white flour (e.g., bread and pasta) are fortified with thiamin in many Western countries.

Vitamin B1 is available in nutritional supplements and for fortification as thiamin hydrochloride and thiamin nitrate (19).
