Protein and amino Acid supplementation in athletes.
Amino acid supplementation is practiced by numerous individuals with the hope of increasing muscle mass and function by increasing available proteins. Theoretically, this makes a great deal of sense; the scientific facts, however, fail to conclusively prove that ingesting more than the recommended dietary allowance of protein has any effect on otherwise healthy adults. Athletes may be the exception to this rule. This review examines the most current literature pertaining to amino acid supplementation, and reports on the potential benefits and risks of this common practice.
