Abstract
Apparent absorption percentages and amount of thiamine excreted in urine after administration of dibenzoylthiamine (DBT), benzoylthiamine monophosphate (BTMP), and thiamine propyldisulfide (TPD) to healthy men were studied comparing with that of thiamine hydrochloride. The amounts of thiamine and its derivatives orally given per day were 10 mg or 30mg respectively equivalent to thiamine hydrochloride. It was observed that DBT was highly absorbed as well as BTMP and TPD, and their apparent absorption percentages were more than two times as that of thiamine. The amount of thiamine in urine after the administration of fat soluble thiamine were also higher than that in the case of thiamine hydrochloride.
