Glutamine is the most abundant amino acid in muscle tissue, but training can significantly reduce glutamine levels as muscle tissue breaks down. Applied Nutrition Glutamine provides 5g of L-Glutamine per serving to support recovery and help replenish levels after exercise. Suggested Use: Consume 1 serving (5g), 1 to 3 times daily at mealtimes. For optimal results consume 1 serving post-training with water or juice.
