Science in Sport (SiS) L-Glutamine

L-Glutamine is the most abundant non-essential amino acid found in muscle tissue. During periods of prolonged and intense exercise, both blood and muscle stores of glutamine can become depleted and remain reduced in the post-exercise recovery period. L-Glutamine is also an important energy source for immune and gut cells and cells.

L-Glutamine supplementation can help replenish the diminished L-Glutamine stores post-exercise. L-Glutamine supplementation before and after exercise may therefore improve muscle (promote muscle recovery), immune and gut function.
