The bioavailability of vitamin B6. Recent findings.
Further clarification of the bioavailability of dietary vitamin B6 requires better analytical data concerning the forms of vitamin B6 in foods as well as the overall composition of foods. The application of radioisotopic and stable-isotopic studies such as those described will provide useful information concerning the inherent bioavailability of the various vitamin B6 compounds. Additional studies should then address the influence of other dietary components on the utilization of the vitamin B6 compounds, using intrinsic and extrinsic enrichment techniques. Care must be taken in interpretation of the results of animal bioassays in the determination of the bioavailability of vitamin B6 in complex diets.
