L-glutamine refers to a free unbound amino acid. Where as glutamine peptide is basically glutamine strung together with peptide bonds. It is probably better know as wheat gluten hydrolysate. These are very pure forms of amino acids and are used in microbiology a lot to grow bacterial cultures with particular nutritional requirements.

I dont know of any reason why it would be any better than L Glutamine, in order for amino acids to be absorbed by the intestines they have to be in single amino form. Meaning they cant be in polypeptide arrangement. The only other thing that I can think of is how they are charged when they are broken into single aminos. Or that the glutamine peptide is just a more pure substance, no fill or other contaminates?
