The issue with most of the Glutamine products available is that they only contain regular L-glutamine and nothing else. Plain L-Glutamine is decent for recovery, but it can be improved. Recently it was discovered that taking L-alanine with L-glutamine was superior over L-glutamine in isolation in animal models.
So when it came time to formulate our Glutamine product we decided that a decent recovery was not enough and that we needed the best. Which is why we included L-Alanine to offer a superior overall Glutamine supplement.
