Thiamine is an essential co-enzyme for carbohydrate metabolism.
Thiamine is well absorbed from the gastrointestinal tract following oral administration, although the absorption of large doses is limited. It is widely distributed to most body tissues and appears in breast milk. Within the cell, thiamine is mostly present as the diphosphate. Thiamine is not stored to any appreciable extent in the body; amounts in excess of the body's requirements are excreted in the urine as unchanged thiamine or metabolites.
