Hi!

"Q: What is the difference between Glutamine Peptides and straight L-Glutamine?

"A: The major difference between the two is that glutamine peptides are more stable in liquids, and in the gut. Free form L-Glutamine can begin to quickly break down if it’s mixed with a liquid and not consumed immediately, and it’s also easily recognized by the gut. As such, much of the L-Glutamine you take in may be absorbed and utilized by the gut before it ever reaches the muscle cells. This is by no means a bad thing, but when you are engaging in resistance exercise, you want to get as much glutamine to the muscle cells as possible, and the best ways to do that are by using glutamine peptides or glutamine precursors. Glutamine peptides are more stable when mixed in liquid, and due to the form they are in, they are not so easily recognized by the gut. This means that more of the actual glutamine will make it’s way into the bloodstream, and thus into the muscle cell, which as a bodybuilder is where you really want it."
