Glutamine- The standard genetic code has 20 encoded amino acids. Glutamine is one those encoded amino acids. Research shows that prolonged consumption of glutamine is effect in anabolic muscle growth. The most non essential amino acid produced by the human body in abundance is the glutamine. The blood brain barrier is something which is crossed directly by very few amino acids. Glutamine is one of those few acids. Skeleton muscles are where the glutamine is stored in the body. It can also be found circulating in the blood stream. In case of illness or injury, it becomes extremely important to consume food high in this amino acid. There are a lot of external dietary sources that provide the amino acid glutamine. Poultry products, dairy products, fish, vegetables like spinach, cabbage, beets; even vegetable juices and fermented food items are a good source of glutamine.
