This Glutamine could be one of, if not the most underrated and undervalued supplements for improving your health, wellness, and athletic performance. Compared to other sports nutrition products, glutamine may not directly influence athletic performance outcomes such as speed, strength, and rep volume. What it does do, however, is keep your body working like a well-oiled machine. Studies prove that l-glutamine benefits your immune system health, digestive health, and accelerates the recovery process. In fact, glutamine could be the best supplement for post-workout muscle recovery. L-glutamine is what’s known as a conditionally essential amino acid. Conditional means that in certain conditions, it becomes essential to supplement or obtain from dietary sources. Your body naturally produces glutamine, yet in times of severe physical stress or trauma, such as prolonged workout durations, and high-intensity training, glutamine stores may become depleted, making it necessary to replenish and restore through supplementation. The twenty amino acids, l-glutamine is the most abundant and naturally occurring amino acid in the human body, constructing nearly 60% of the amino acid pool in your muscle tissue. Like other essential amino acids, yet unlike non-essential amino acids naturally produced by the body, l-glutamine can cross the blood-brain barrier, giving it the ability to freely enter the brain, making it vital in the process of nitrogen transport, acid-base regulation, gluconeogenesis, while also working as a precursor of nucleotide bases and the antioxidant glutathione. GNC L-Glutamine is one of the best muscle building and muscle recovery supplements now day in market.
