There are certain reasons as to why physically active individuals need to take vitamin supplements. Taking for example, in certain types of athletic activity such as gymnastics and ballet, athletes may undertake prolonged semi-starvation or starvation diets. Although this is not a recommended procedure, some athletes may still do it in order to obtain or maintain an optimal body weight for competition. In such situations, when the energy intake may be well below 1,200-1,600 calories per day, many surveys have shown that athletes may not be receiving enough vitamins.
Research suggests that vitamin depletion, mainly the water soluble vitamins, can happen quickly in humans on low calorie diets and that these vitamins should be replenished daily. Athletes may also need vitamin supplementation if they are subsisting on poor diets. Moreover, some vitamin requirements are increased in pregnant women and the elderly, so those who exercise need to consume vitamin rich diets (Williams, H. Melvin, 2007)
In general, athletes should obtain all the vitamins and minerals from their diet. Since athletes use up more energy as compared to sedentary people, they probably will eat more too, and so any extra requirement for vitamins or minerals should be met by their increased food intake (providing the diet is balanced).
However, there have also been some studies which have shown that many athletes don't have sufficient vitamin and mineral intakes. This may be due to the fact that they restrict calorie intake for weight control. The other reasons for insufficient vitamin and mineral intake include irregular training routines which makes meal planning difficult and following a dietary that is not providing a balanced diet (Vitamins and minerals and the athlete Website, 2008).
