Glutamine is the most abundant amino acid found in skeletal muscle tissue, making up about 60% of its total content, and is the predominant non-essential amino acid used during exercise. Although glutamine can be obtained from the diet, supplementation is often required to replace losses incurred during workouts or training. Replenish your glutamine supply with our high-quality, natural fermented l-glutamine powder to improve muscle recovery so that you can achieve optimal results from your workouts and training.
