Glutamine: the nonessential amino acid for performance enhancement

Curr Sports Med Rep. 2007 Jul;6(4):265-8. doi: 10.1007/s11932-007-0043-6.


Glutamine is a popular dietary supplement consumed for purported ergogenic benefits of increased strength, quicker recovery, decreased frequency of respiratory infections, and prevention of overtraining. From a biochemical standpoint, glutamine does play a physiologic role in each of these areas, but it remains only one of a host of factors involved. This review examines the effects of glutamine on exercise and demonstrates a lack of evidence for definitive positive ergogenic benefits as a result of glutamine supplementation.
