Document Summary

Controversial because we are not sure whether or not they enhance athletic performance. Training serves an athlete better than an pills or powders. For the large majority of ergogenic aids research findings do not support the claims made for them. Athletes to hear that a product is ergogenic should ask who is making the claim and will profit from the sale. Some athletes particularly bodybuilders and weightlifters believe that consuming large doses of amino acids will help build muscles. Amino acid supplements are unnecessary: healthy athletes eating a well balanced diet never need them and in a few fortunate cases these supplements have proven dangerous, taking acid puts the body into too much too little behind. Amino acids compete for carriers and overdose of one can limit the availability for some other needed amino acids. Supplements can also lead to digestive disturbances excess and water accumulation and the digestive tract.
