Vitamin B6 status of Finnish elderly. Comparison with Dutch younger adults and elderly. The effect of supplementation.

Author information

  • 1University of Helsinki, Finland.


About 25% of Finnish and Dutch elderly appeared to be more or less deficient in vitamin B6 as compared to younger adults. Deficiency was observed at the cellular (PLP, EGOT and alpha-EGOT) as well as at the plasma level (PLP). The benefit of a one-year daily supplementation with 2 mg of pyridoxine-HCl was investigated at the biochemical and psychological level as compared to a placebo group. After one year, none of the supplemented elderly was deficient in biochemical terms. At the psychological level and at the level of general well-being, the elderly supplemented with vitamin B6 showed slight improvements. However, for the psychological variables significant correlations with the vitamin B6 parameters were not observed. Plasma fatty acids (e.g. gamma-linolenic acid) showed no correlation with the vitamin B6 status.
