  • Muscle Tissue Preservation Of the 20 amino acids required for protein synthesis

Glutamine is the most abundant. It makes up 50% of all amino acids in the blood and 60% of those in the body. Not only is glutamine necessary to maintain positive nitrogen balance and protein synthesis, but also it has recently been shown to prevent muscle loss by influencing myostatin levels.  Myostatin is a protein that inhibits muscle differentiation and growth. Its increased bioactivity has been observed in glucocorticoid-induced hyper catabolism and is associated with several pathologies characterized by marked skeletal muscle depletion.

  • Support During and Recovery After Stress States During stress states 

the body’s glutamine requirement exceeds supply, severely reducing both plasma and skeletal muscle pools of free glutamine. Without adequate glutamine to meet the needs of the:-

  1. Intestine
  2. Immune System
  3. Vital Organs

A negative nitrogen balance and catabolism can result.  Nitrogen is necessary to repair wounds and keep the vital organs functioning; approximately one third of this nitrogen comes from glutamine. Adequate nutrition, which includes glutamine, can help spare host energy reserves and impede recovery complications.  In fact, it has been recommended that patients preparing for elective surgery ready themselves nutritionally, in part through glutamine supplementation, to optimize recovery. Research also suggests glutamine may help diminish risks associated with conventional therapeutics

such as

  • High-dose chemotherapy and radiation by supporting mucosal integrity
  • Immune competence
  • Glutathione biosynthesis

Fee From Amino Acid Supplements

  • Intestinal Health and Barrier Function

The greatest amount of glutamine is used by enterocytes. As their preferred fuel source, glutamine is necessary for their maintenance and healthy turnover. Supplementation may therefore enhance mucosal health. A healthy intestinal mucosa not only supports optimal nutrient absorption, but it also supports mucosal immune function and provides a barrier between bacteria and their products in the intestines and the bloodstream.

  • Disruption of intestinal barrier function can lead to decreases in mucosal immune activity and increases in escaping toxins and bacteria, resulting in:-
  1. Infections 
  2. Illness,
  3. Allergic reactions 
  4. Skin conditions & more 

In various experimental models, glutamine administration has been shown to reduce epithelial cell death and preserve or improve barrier function.

For instance, in an animal model of chemotherapy-induced intestinal damage, glutamine decreased the severity of intestinal injury perhaps through improved intestinal cell turnover and enhanced antioxidant activity.

Glutamine is the most abundant free amino acid in the body and is an energy substrate for most cells especially enterocytes (intestinal epithelial cells) and immune cells. It is also an essential component for numerous metabolic functions, including acid-base (pH) homeostasis; nitrogen supply; neurotransmitter production; and synthesis of glutathione, glucose, proteins, and nucleic acids. Glutamine is primarily synthesized and stored in skeletal muscle. It is considered a conditionally essential amino acid because, under normal circumstances, the body can manufacture enough to sustain physiological demands. However, under metabolic stress such as:-

  • Illness/Disease
  • Injury
  • Infection
  • Surgery
  • Chemotherapy
  • Prolonged Exercise
  • Environmental Stress

Glutamine is released from body stores into the bloodstream and transported to tissues in deficit. Increased demands make exogenous glutamine sources (food, supplements) a necessity.

L-Glutamine (glutamine) is the most abundant amino acid in the body and is necessary for the maintenance of many metabolic functions. Under situations of stress, physiological demands increase, triggering a need for glutamine supplementation. For ease of dosing, Adaptogen Research L-Glutamine provides 5 grams of this amino acid per scoop to help replenish the body’s stores and support glutamine’s many functional roles.*

L-Glutamine 

Glutamine is thought to have ergogenic effects through its influences on fluid and electrolyte uptake, glutamine pool repletion after intense training, stimulation of muscle glycogen synthesis, and ability to increase growth hormone levels. While ergogenic effects are supported from a biochemical standpoint, more definitive studies are needed
