Vitamins are crucial for turning food into energy. Since athletes have high metabolic rates and need their bodies to function at intense levels, they have higher micronutrient needs than non-athletes. In addition, exercise stresses the metabolic pathways where vitamins and minerals are used and may also result in biochemical adaptations that increase micronutrient needs. Routine exercise is another way of speeding up the gain and loss of vitamins and minerals from the body.
Independently of whether you are training for a competition or simply working out in order to be fit, vitamin deficiency can have negative effects to your social behaviour, body and cognitive performance.
