Ergogenic aids: evaluating sport nutrition products.
The desire to win leads physically active individuals to look for anything to improve performance.

To evaluate such products, one must consider the physiological sense of the claims, the supportive evidence provided, the research articles quoted, and the legal and health implications of use.
