Vitamin Intake

Some aspects of intake of the individual vitamins in athletes have been discussed in the previous paragraphs. Here we will discuss some general influences on daily vitamin intake. Vitamins are present in a wide variety of fresh unprocessed foods such as vegetables, fruits, berries, tubers and grains. A normal well balanced diet composed of a variety of foods is therefore believed to supply all necessary vitamins in sufficient quantities. However, in some situations the intake may be lower than the current RDA. Such a situation may occur when low energetic diets or unbalanced diets are consumed. This first situation occurs frequently in athletes who compete in low weight categories and follow weight reducing diet-training programmes. Alternatively, athletes who have to maintain a low body weight for prolonged periods of time such as female dancers and gymnasts may be prone to low vitamin intakes (Table 1).
