L Gluthamine to immune system and healing gut.

I saw some places saying that L Glutamine helps the gut and also our immune system. One guy took 2 grams and said that he was sleeping verter and got increased libido from it.

Anybody tried it? Is it helpful?

I think Grizz will like it because he always say to support the immune system, I just don't think Iodine is so good to our health, I'm affraid to get some thyroid disorder and also become dependable from iodine, but that is not the discussion.
