Glutamine is the most abundant free-form amino acid in muscle, comprising over 50% of the free-form amino acids. During and after intense training, large amounts of glutamine are released from muscles. Supplementing with L-glutamine could help ensure that muscles are quickly refuelled possibly helping prevent muscle breakdown, and ultimately boosting muscle growth. L-glutamine may be helpful to the performance of both power and endurance athletes. Sci-MX’s Glutamine Pro is the highest pharmaceutical grade available which ensures rapid absorption and maximum results.
