Glutamine, What we should know

Glutamine Amino acids


L-glutamine is the most abundant free amino acid in the body that accounts for over 60% of free amino acids with in the blood system, internal organs, skeletal muscle, tissue and brain. This critical amino acid is essential for a vast number of different functions within the body which can improve the overall health conditions. Glutamine plays an important role in cardiovascular function by providing a key energy source for endothelial cells that line blood vessels. It regulates nitric oxide synthesis by these endothelial cells, and maintains blood vessel tone and prevents inflammation in the walls of blood vessel. Glutamine enhances healthy neurological function and has strong potentials of improving mood, memory and concentration. When Glutamine crosses the blood-brain barrier, it is converted into L-glutamic acid, which aids in cerebral function.  Glutamic acid has unique characteristics of converting into energy source for neuronal cells when blood sugar is low. This characteristic is said to be the reason for glutamine’s ability to damper alcohol cravings and sugar. Glutamine is also an essential part of our digestive system, hence its regulation of cellular reproduction.
Glutamine equally aids the regulation of cells as they absorb water across the junction between blood stream and the small intestine, which protects the body from losing fluid and experiencing dehydration. When the body does not absorb water, it leads to diarrhea, which can result to loss of vital nutrients.
It plays a vital role in both cellular and systematic processes of detoxification; it acts as a major energy source for lymphatic cells helping in the removal of toxic debris.  Glutamine acts as a transport agent in the removal of ammonia out of major tissues, such as the brain, from where it is transported to the liver for its conversion into urea. Increased Infections

Deficiency can lead to increased risk of infection.  Low levels of glutamine can lead to increased susceptibility to infection, because during times illness or excessive exercise, the body gives out cortisol, which ultimately reduces glutamine levels. Glutamine deficiency can equally lead to weight loss for people that suffer from chronic gastrointestinal distress such as inflammatory bowel diseases. Low levels of glutamine can lead to bowel changes by influencing the gastrointestinal system in the body. The body digests food and converts part of it to glucose to be utilized by the cells for energy; glutamine steps in to supply energy to the cells. Low glutamine levels result to reduction to the activities of the cell in this part of the body. In many situations, glutamine has been used as a supplement for those with chronic disorders that cause excess diarrhea.

L-glutamine can be found in animal proteins such as dairy and meat, in combination with plant based protein sources such as raw spinach, beans, parsley and red cabbage. In most cases, the plant proteins are not as easily digestible when compared with the animal proteins. Rich food sources of L-glutamine include grass-fed beef, bone broth, Chinese cabbage, cottage cheese, spirulina, asparagus, turkey, wild caught fish (salmon, cod and tuna), broccoli raab, beans, and meat. It is recommended that each day; you take in three or more L-glutamine foods.
