yeah glutamine is an amino acid one of the building blocks of proteins. I don't think it is an essential amino acid- one of the ones your body can't synthesize and need to ingest to get a hold of them. the ones that we can't make in our bodies include valine, isoleucine, threonine, tryptophan, leucine, lysine,phenylalanine,and methionine (ask how I know?- VITTLL PM). other ones can become essential, but for the most of us that is it. I sjust eat a lot of food and consider my bases covered.
