Common Dietary Supplements Used by Elite Athletes
For my 4rth article in my series of articles on dietary supplements that may help to improve athletic performance, I am going to review a recent study published in the Clinical Journal of Sport Medicine (Erdman et al, 2007) which reviews common dietary supplements used by elite Canadian athletes.
Though it is generally accepted that elite athletes are more likely to use dietary supplements than people who do not exercise, it is important to get an understanding of which dietary supplements are most commonly used and for what reasons. Not surprisingly, the most common dietary supplements used included energy drinks/bars, multivitamins, protein supplements, and vitamin C. Further, common reasons for athletes using dietary supplements included: increase energy, maintain health, improve exercise recovery, add/maintain muscle mass, and to enhance immunity.
