Most of glutamine taken orally doesnt make it past your stomach anyhow.

I agree with you nite. I too have supplemented glutamine and it didnt do anything. Although I do believe my ON Whey protein helps my Immune system ALOT. That of course has glutamine......

Some researchers argue that the fall in glutamine levels after exhausting exercise may be related to suppression of the immune system. One investigation of 14 studies found that the self-reported incidence of illness in marathon runners was 32% lower in subjects who had consumed glutamine [9]. However, the mechanism for this is unknown, as most studies have found that glutamine fails to effect exercise-related changes in immune parameters [7, 9, 15]. Two studies have found that glutamine slightly blunts the postexercise increase in circulating neutrophils, but it is unknown whether this is clinically significant [9, 15]. One study also found that among certain marathon runners, glutamine speeded the restoration of circulating lymphocytes [9]. The differences in findings is probably related to differences in study design. It could be that glutamine does not significantly alter the magnitude of postexercise immune changes, but does speed the rate of recovery(of the immune system - Traps), especially in the case of extremely taxing exercise such as marathon running.
