L-Glutamine is the most common amino acid found in the body. It’s an essential amino acid, meaning the body can produce it internally; having said that, depletion of the amino acid can often occur in times of stress, sickness or after intense workouts. Supplementing with L-Glutamine will help in the recovery process and muscle repair in your post workout routine. Studies have revealed that L-Glutamine can help minimise breakdown of muscle and can improve protein metabolism. This is especially useful for those dieting and wanting to preserve muscle.
