Glutamine is an amino acid that is found naturally in the body. Through weight training and high endurance activities, glutamine is heavily metabolized. Studies have shown that glutamine supplements can help the body recover after intense training. Glutamine is also a great supplement to heal the gut and improve digestive function. Athletes take glutamine to stimulate the release of growth hormone, volumize muscle cells, reduce muscle soreness and enhance their immune system. You already train hard, so make sure you recover strong and get back to the gym as quickly as possible - the weights are "weighting" for you!
