L-glutamine is the most prevalent amino acid in the bloodstream. It is found in high concentration in the gastrointestinal tract, which is its greatest user. Various stress factors – such as malnutrition and high-level athletic training – can adversely affect absorption in the small intestine. Evidence suggests supplemental L-glutamine benefits gastrointestinal health, maintains immune health, and helps restore plasma glutamine levels depleted after periods of physical stress, such as prolonged exhaustive exercise.*
