Vitamins are the cell biocatalysts, indispensable factors in performing the basic body functions. Fat-soluble vitamins are not involved in processes related to musscle contractions and energy expenditure, but they can affect physical performance indirectly because they are important for immune function (vitamin A, vitamin D, vitamin E), antioxidant function (vitamin A, vitamin E) or bone methabolism (vitamin D, vitamin K). Currently there are no clear recommendations for increase of fat-solubile vitamins intake in athletes, as well as evidence that athletic performance may be improved due to fat-solubile vitamins supplementation. In a small number of studies, it was shown that an antioxidant effect of beta carotene and vitamin E can prevent muscle damage and facilitate recovery after exercise. Also, athletes who perform the exercises in the halls should be informed about the necessity of sun exposure, as vitamin D is synthesised in the skin.

Most athletes are not familiar with their needs for vitamins and trace elements, and take these compounds as supplements without consulting a nutritionist. It is important to emphasize that liposulubile vitamins are deposited in the body and can cause hypervitaminosis and toxic effects if taken in excess.

It is indisputable that the lack of any fat-soluble vitamin cause problems in normal physiological processes, but supplementation is generally not required in athlets who have a well-balanced diet. Acta Medica Medianae 2013;52(4):63-68.
