Abstract
For many years, studies have been made to improve the performance of athletes in
competitions and, therefore, the use of supplements has been increasing gradually. But the
problem is that it is known that dietary supplements are not always free from unwanted
substances, often contaminated with substances banned by sports organizations. The
objective of this review was to explain the danger of the presence of illegal substances in
food supplements to practitioners of recreational exercise and elite athletes. A literature
review was made on bibliographic databases such as Medline, Scopus and Pubmed, journals and Organizations and Government Agencies websites. Were highlighted in this
review laws in force on the subject, the strategies implemented to guide athletes and people
involved in sport, illegal substances most commonly found in food supplements and the
types of supplements that are more contaminated. Several studies were performed to verify
the presence of such contaminants and the results were alarming, raising concerns of
athletes, coaches and teams on the use of dietary supplements. Unfortunately, the laws and
control over this problem is not severe enough to end the situation. Therefore, sports
organizations and committees must inform athletes about supplements safer to use, and
would be important to create new laws to control the production.
