Glutamine has recently been the focus of much scientific interest. A growing body of evidence suggests that during certain stressful times, the body may require more glutamine than it can produce. Under these circumstances glutamine may be considered a "conditionally essential" amino acid. Glutamine is involved in maintaining a positive nitrogen balance (an anabolic state) & also aids rapidly growing cells (immune system lymphocytes & intestinal cell enterocytes). In addition, glutamine is a regulator of acid-base balance & a nitrogen transporter.* Do Not Eat Freshness Packet Enclosed.
