The vitamin B1 status of 599 pregnant women was investigated by means of the erythrocyte transketolase-activation test. No correlation between the vitamin B1 status and the course or outcome of pregnancy could be demonstrated. In contrast, 25-30% were found to be thiamin-depleted in respect of erythrocyte transketolase saturation in comparison with a group of over 300 male and female blood donors. This proportion remained constant throughout gestation. As a consequence, vitamin B1 supplementation is recommended to prevent subclinical metabolic disturbances of thiamin-dependent enzyme systems.
