what are some quality brands that sell l-glutamine

hey im wanting to buy some l-glutamine and i just want to make sure i get good quality.
dont want ne cheap brands or whatever ... so itd be nice if someone could tell me some good brands for l-glutamine.

also ... could someone give me some good protein powder brands .... i use GNC ... but i know there are other good ones out there .. like prolab, or designer, or 100% whey protein and such.
but yea ... thnx a lot.
and last of all .. is WHEY PROTEIN ISOLATE/CONCENTRATE better to take than just WHEY PROTEIN ISOLATE. i hear that isolate and concentrate is good too... maybe its just good cuz its decent for the price.. but yea.
thnx again.
 
i've heard that glutamine is produces in only a few places. so that most companies buy theirs from probably the same place so it would all be pretty much the same. eas, prolab, optimum are a few good brand names.

optimum nutrition 100% whey is probably the most favorite brand.

and you're right. a whey isolate/concentrate is the best bang for your buck.
 
alritey
thnx abear ...

i got just the GNC glutamine powder .... and GNC protein pow ...
its pretty good ... and im sure its quality.
but thnx for the info...

if i buy just whey isolate protein powder ... its still works really good tho right ?
 
glutamine is an amino acid ... which is abundant in your body.
but if you do an intense exercise ... something like weightlifting .... or experience alot of stress, your glutamine levels can be depleted. which you don't want if your trying to gain muscle and working out every second day.

glutamine carries nitrogen to the muscles .... the more glutamine u have in your body ... the faster your muscles heal and recuperate from a workout. It also helps prevent muscle catabolism (burning your own muscle) .... which is really nice if your doing alot of cardio along with weightlifting.

so it mainly just increases protein metabolism (really helps you recover faster + regain strength) and helps prevent you burning off your own muscle... and not to mention it also helps a bit with muscle growth since it increases ability to secrete growth hormones.

thats what it does for muscles ... it has other roles with some other parts of your body, but that just doesnt belong in this forum now does it hehe.
