L-Glutamine powder by German Pharma comes in a 500g size which provides 100 5g servings, 5g is a studied dose of L-Glutamine to improve performance(1) 

L-Glutamine is a very important amino acid (there are a total of 20 amino acids) in fact L-Glutamine is the most abundant in the blood and in skeletal muscle, making it a very important amino acid for everyday bodily activities 

Training, whether that be lifting heavy weights, running, rugby, crossfit or anything related to strenuous exercise will deplete the stores of L-Glutamine within your body, this makes recovery harder and indeed makes the regeneration and repair of muscle cells harder.   This is where supplementation comes in. Supplementing 5-10g daily with L-Glutamine has shown in studies to improve performance and increase recovery times after anaerobic exercise (2)
