Glutamine is the most abundant amino acid in muscle tissue, essential for numerous bodily functions, including immune support, gut health, and muscle recovery. Although found in small amounts in many foods, intense physical training can significantly deplete the body’s glutamine levels. For this reason, glutamine supplements are widely favored by athletes to support recovery, maintain muscle mass, and promote overall endurance. Replenishing glutamine post-workout may aid in faster muscle repair, reduce muscle soreness, and help bring the body back to optimal performance levels.
