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.&ampnbsp; Under these circumstances Glutamine may be considered a &ampquot;conditionally essential&ampquot; amino acid.&ampnbsp; Glutamine is involved in maintaining a positive nitrogen balance (an anabolic state) and also aids rapidly growing cells (immune system lymphocytes and intestinal cell enterocytes). In addition, Glutamine is a regulator of acid-base balance and a nitrogen transporter.*
