I was checking into Whey supplements, and I noticed that the "Optimum Nutrition, 100% Natural 5lb Chocolate" lists L-Glutamic Acid at 4072mg. Does anyone know if this is the same as an L-Glutamine supplement? Just trying to see if I have to purchase Glutamine on its own. Here is the link to the product: http://www.sndcanada.com/gc/gc_item.exe?F=D&K=ON-H110&R=H%2FCatalog%3AProtein%20Powder%20-%205%20lb%20container&ID=0207235041642315946226&Z9=0
There are a lot of other things listed here as well... if anyone sees anything that looks detrimental, please let me know!

I was searching the forum for glutamine and came across this question that was not answered.. thought I would bump it up to see if there are any responses.. I looked at my current whey powder, pro rated, and it has 14.7 grams of glutamic acid per 100 grams of whey powder.

most of them have a decent amount of glutamine and other amino acids in.

Clear as mud.
Glutamic acid and glutamine are related but not the same. Combining glutamic acid with ammonia forms glutamine.
What's the difference between Glutamine, L-glutamine, Glutamic Acid, and Glutamine Peptides?
Glutamine is the amino acid in its free-form, which means it's in its whole food state, whenever you eat foods such as almonds and peanuts your ingesting glutamine amino acids. L-Glutamine is basically the same thing. Its glutamine in its free-form (whole food). The majority of supplement companies sell L-glutamine and tout it as the best form, which it is not.
Glutamic Acid is familiar if one turns over their container of protein powder and sees "glutamic acid". Why not glutamine instead of glutamic acid? "The reason is that the acid hydrolysis stage of the analysis converts the glutamine into glutamic acid, releasing ammonia. Thus the glutamic acid level actually represents the combined levels of glutamine and glutamic acid." (ref). One can figure out the amount of glutamine in the glutamic acid content fairly easy. In animal proteins such as whey, casein, milk, and egg proteins 50% is actually glutamine. In plant proteins such as soy, 80% is glutamine.
