Vitamin B & Performance

B vitamins effects on exercise performance

B vitamins play a big part in energy production. Therefore, these vitamins are essential for optimal exercise performance.

An experiment examined the effect of a 11-week diet restricted in vitamin B1, B2, and/or B6 on performance.

24 healthy men were enlisted and consumed normal food products and adequate energy intake. The food was picked so that one or more of the B vitamins were restricted (<55% RDA).The performance of their exercises were measured with a maximal test on a cycle ergometer.

The group that was on a vitamin B restricted diet had a lowered maximal workload and maximal oxygen consumption (VO2max) during the 11-weeks by 6% and 7%, respectively.

This study concludes that diets that are low in vitamin B are detrimental for performance. So increased intake of B vitamins will improve exercise performance.
