Yep - there are 3 grams added. Glutamine increases insulin secretion when added to carbohydrate and protein. Therefore it's added for the insulinogenic properties.
When I say glutamine is "worthless" (although I doubt I ever said it in that way), I'm talking about its direct value as a muscle building supplement. Dave Barr and I have written complete reviews on this site of why glutamine may not be as useful for bodybuilders and athletes as sports supplement companies proclaim.
As with most other things -- glutamine has an effect in some domains and not in others.
