Purpose of and why people supplement with L-Glutamine?

[Varga]

I only use Glutamine on workout days 5gr or so and it cuts about 1 day off my recovery.....If that's not proof enough then don't buy it. For those who might not have seen the effects of glutamine ck your diet and training because if you train too hard and not eat enough no amount of glutamine will help you.....but if everything is spot on glutamine is a great compound.

Never liked it, best for immune system and thats about it BCAA's are more important along with arganine but you can get BCAA's in most of your shakes anyhow.
