Area of Science:

  • Biochemistry
  • Human Metabolism
  • Nutritional Science

Background:

  • Glutamine is a non-essential amino acid, abundant in the body and diet.
  • It functions as a key inter-organ transporter of nitrogen and carbon.
  • Skeletal muscle is the primary site of glutamine production.

Purpose of the Study:

  • To review recent advancements in understanding glutamine's metabolic role.
  • To highlight outcomes from new clinical studies on glutamine supplementation.
  • To inform clinical decision-making regarding glutamine's use.

Main Methods:

  • Review of recent clinical studies and metabolic research.
  • Analysis of glutamine's role in human physiology, especially during stress.
  • Evaluation of data on glutamine supplementation efficacy.

Main Results:

  • Glutamine is crucial during physiological stress, becoming conditionally essential.
  • Recent clinical trials demonstrate significant positive outcomes with glutamine supplementation.
  • New insights reveal glutamine's expanded importance in metabolic regulation.

Conclusions:

  • Glutamine plays a critical role in metabolic homeostasis, particularly under stress conditions.
  • Evidence supports glutamine supplementation as a potentially valuable therapeutic strategy.
  • Clinical practice should consider recent findings on glutamine's benefits.
