What Is L-Glutamine?

L-glutamine is what’s known as a conditionally essential amino acid. Conditional meaning 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.

Of the twenty amino acids, l-glutamine is objectively 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.
