Thiamine is a water-soluble vitamin that is an important coenzyme for various metabolic processes in the body. These include the regulation of glucose metabolism, the Krebs cycle (generates ATP), the pentose shunt (generates NADPH), and maintenance of sodium/potassium gradients in the brain (necessary for conducting nerve impulses). Thiamine is mostly obtained from dietary intake with absorption occurring in the jejunum and ileum. After traveling to the liver, thiamine spends a relatively short amount of time in the blood before distributing to tissues throughout
