Henry Blooms L-Glutamine Powder is important for repairing and building muscle and reducing muscle catabolism (breakdown) making it a valuable aid for those undergoing heavy workouts. People who engage in intense exercise have an increased dietary requirement to restore L-glutamine levels to normal to avoid loss of muscle mass. Henry Blooms L-Glutamine Powder is especially useful post-workout, to replenish depleted glutamine stores. L-Glutamine also helps reduce impairment of immune function brought on by exercise. L-Glutamine plays an important role in gut health. It protects the intestinal mucosa from damage and promotes repair of the gut wall. Breakdown of the mucosal lining of the gut causes increased gut permeability. The gut lining contains rows of tall columnar epithelial cells, all tightly packed together. It is here that L-Glutamine is involved in promoting strong junctions, reducing cell breakdown and supporting cell repair. L-Glutamine functions to support the integrity of the gastrointestinal tract.
