Abstract: The bioequivalence of thiamine in two therapeutical used vitamin preparations was tested in a group of 10 healthy males. Thiamine was administered either as lipophilic benfotiamin or as watersoluble thiamine mononitrate. The biokinetic data, given as A UC (area under the curve) ad Cmax (maximal concentration) in plasma and hemolysate, indicated a signifcant improved bioavailability of the lipidsoluble vitamin, although the oral administered dose was 60% lower than that of the watersoluble derivative. The superior cellular effectiveness of benfotiamin could also be deduced from the short-term stimulation of the thiamin dependent transketolase activity in erythrocytes.
