Vitamins and exercise--an update.

Abstract:

:Although no conclusive evidence exists to suggest that vitamin supplementation improves athletic performance in nutritionally adequate individuals, exercise may increase requirements for certain vitamins in individuals with marginal vitamin stores. This review summarizes results from recent research studies of vitamins and exercise. Exercise increased the requirement for riboflavin and vitamin C; however, vitamin supplementation improved the ability to train only in vitamin C-depleted individuals. No measurable effect of supplemental thiamin, riboflavin, or vitamin B6 on performance was observed in any of the reported studies. Exercise acutely affected vitamin B6 metabolism. Confusion regarding vitamin supplementation and exercise performance may stem from a lack of adequate research data. Recommendations for future research are presented.
