SSN Glutamine is a powerfully beneficial amino acid, being the most abundant amino acid in muscle cells. With extremely hard training, intra-muscular glutamine levels can drop and when muscle glutamine levels fall, muscle cell volume decreases resulting in muscle catabolism (muscle loss). As glutamine plays a role in immune responses, this fall in glutamine levels partly explains the increased susceptibility of hard training athletes to infections. Supplementing with glutamine during intense training cycles helps prevent a drop in glutamine levels, thereby helping maintain proper cell volume & hydration levels as well as providing a potent anti-catabolic (muscle preserving) effect. Research and real world evidence strongly suggests that L-glutamine supplementation in hard training athletes plays an important role in assisting with recovery, enhancing muscle cell volume and preventing muscle catabolism by maintaining optimal muscle anabolism. To maximise L-glutamines anabolic, anti- catabolic and cell volumising effects, consume extra fluid every day and increase your daily protein intake by way of a high quality pure protein supplement such as our 100% Whey Protein.
