“Glutamine is among one of the twenty amino acids in human body. It is the precursor of glutamic acid, in which the side chain hydroxyl group is removed by the amino functional group. Thus can also be known as the amino of glutamic acid. It is the most abundant amino acid in the human blood, and is especially important in conditions like GIT disorder and athletic training.”

About 90% of glutamine is synthesized by muscle mass, by an enzyme called glutamine synthetase. Other organs like the brain, lungs and liver also synthesize glutamine. Among these the liver is recognized more for glutamine metabolism rather than its production.
It is mostly required my intestines, activated immune cells, cancer cells and kidney cells. Some of the glutamine is also recognized as an anticancer drug.
Glutamine is included among those amino acids that cross the blood brain barrier, and found in blood and stored mostly in skeletal muscle. As far as food is concerned it is found in beef, chicken, fish, eggs, dairy products, wheat, cabbage, beets, beans, spinach, milk, and parsley. Small amounts of free L-glutamine are also found in vegetable juices.

The question arose in mind that why human body requires glutamine?. Here come the answers it performs following important functions in human body:
Nowadays there are an endless supply of glutamine supplements that are available, as during exercise the body’s stores of glutamine decreases. The glutamine which is present in blood is utilized in counteracting the effect of exercise, again in order to gain the lost amount of blood glutamine body catabolizes the glutamine from the muscles. Thus if there might be deficiency of glutamine then it leads to immune system deficiency and muscle loss. For this purpose glutamine supplements are and found on www.musclecoach.com. In the condition of stress the glutamine of muscle decreases. When we train the body is in a stressed condition and becomes catabolic, this is when glutamine may become deficient. In such conditions if we supplement with glutemine products protein synthesis occurs and we build muscle.
