I've heard a lot of people trash talking l-glutamine. They reference studies who state that l-glutamine supplementation does not significantly raise plasma l-glutamine levels. Are we really interested in plasma l-glutamine levels? I was under the impression that 60% of the free form amino acids in our muscles are l-glutamine. Shouldn't the studies be concerned with these levels rather than plasma levels?
