[There goes that popular theory that glutamine helps preserver your precious muscle after workouts or in general.]
Obviously when I received the original article about glutamine's super muscle building benefits, I was curious myself. After finding the research done by David Barr, I was so excited I couldn't wait to tell you. I'm not going to provide a full reference list - they're all right at the end of David Barr's article which will be included here for your reference.
At this point you're probably thinking that glutamine is a worthless supplement.
David Barr makes a final comment after all his research that glutamine isn't a worthwhile supplement to the resistance trainer who is on a proper bodybuilding diet with post workout nutrition. Of course he doesn't call glutamine a dramatic supplement with muscle building benefits. He does show some instances where glutamine might be beneficial in legitimate wasting conditions. It's not exactly a black and white answer.
The bottom line?
At this point, I would really encourage you to do your own research. Granted, David has done a bang up job! Even I believed in glutamine for bodybuilding until I was faced tolook at real evidence and not a magazine ad or a myth from a big guy at the gym.
