"Glutamine is the most abundant free-form amino acid in muscle, comprising over 50% of the free amino acids. During and after intense training, large amounts of glutamine are released from muscle. The deficit created by this triggers the conversion of other amino acids into glutamine, which is a catabolic (muscle wasting) action. Oral supplementation of L-Glutamine helps to prevent muscle wastage caused by this natural recovery process. Glutamine has become increasingly prominent as new studies reveal its unique contribution to protein synthesis, muscle growth, anti-catabolic (preventing muscle tissue breakdown) and growth hormone elevating effects.
