Glutamine is a conditionally essential amino acid that is the most abundant amino acid in the blood and accounts for more than 60% of the amino acid pool of the body.
Glutamine exhibits many regulatory functions in the body. Researches show that glutamine has a potent anti catabolic effect. It is important as a nitrogen shuttle, and also has important role in normal immune function.
Prolonged exercise is associated with a fall in the plasma concentration of glutamine. Supplements consumption may be beneficial by maintaining plasma glutamine concentration.
