Glutamine is one of the 20 amino acids encoded by genes. It is involved in biochemical changes related to the regulation of nitrogen and pH. Glutamine is also an essential nutrient for lymphocyte proliferation and cytokine production, phagocytic and secretory activity of macrophages, and the destruction of inert bacteria. It also plays a physiological role in various metabolic processes: as an intermediate in energy metabolism and as a substrate for the synthesis of peptides and non-peptides such as nucleotide bases, glutathione, and neurotransmitters.

When the body is under stress, such as in cases of chronic diseases, trauma, emergencies, sepsis, etc., the amount of glutathione is reduced and drawn from muscles, among other sources, which is not beneficial. The amount of glutathione is reduced and drawn from muscles, among other sources, which is not beneficial.

In situations of increased cellular demand for components for metabolic functions, glutamine can become essential. Unfortunately, its availability may be compromised due to altered homeostasis in amino acid metabolism between tissues. For this reason, glutamine is now part of clinical nutritional supplementation protocols and is recommended for immunocompromised individuals. [1]

Studies have also shown that glutamine supplementation leads to greater weight loss in people who engage in regular physical activity[2]. [2]

In summary, the dietary supplement L-Glutamine 5000 mg 454 g from Now Foods is a product mainly intended for people who engage in regular physical activity. It contains high-quality powdered glutamine, which may contribute to weight reduction and whose effects on the immune system have been demonstrated.
