Background: Different in vitro studies indicate that yoghurt bacteria are able to generate several water-soluble vitamins and therefore yoghurt could be a good source of these micronutrients. However, it is discussed controversially whether lactobacilli or other viable bacteria release the synthesized vitamins or utilize vitamins from their surrounding. This study was carried out to investigate if probiotic and traditional yoghurt bacteria, respectively are able to influence the status of different B-vitamins (B1, B2, B6) in young healthy women.
Methods: In this investigation female volunteers consumed 100g/day of probiotic (n=17) or conventional yoghurt (n=16) for 2 weeks (T1-T2) and 200g/day for another 2 weeks (T2-T3). A wash-out phase lasting 2 weeks followed. Plasma and urine concentrations of vitamins B1, B2 and B6 were analyzed using HPLC-methods, the functional parameters, i.e. the erythrocyte transketolase (α-ETK), erythrocyte glutathione reductase (α-EGR) and glutamic oxaloacetic transaminase (α-EGOT) were determined photometrically.
Results: The plasma levels of thiamine increased significantly in both, the probiotic (p
