Glutamine can be found circulating in the blood, as well as stored in the skeletal muscles and liver, in concentrations ranging from 10- to 100-fold higher than any other amino acid.1

Glutamine is utilized in a number of vital functions, including protein synthesis and production of the nucleotide units that make up DNA and RNA. Because of its importance in many cellular functions, glutamine is consumed at especially high rates during activities involving intense exercise.1 It is an important energy source for cells lining the gut and immune cells and critical for healthy gut and immune function.2,3 It is also a precursor of the brain neurotransmitter glutamate.1,4
