420 mg per serving in the endurox r4 recovery drink I use. Glutamic acid + l glutamine 2.6g/serv. This is the best recovery drink I've ever used.

I used to use it. I think it's pretty much hype though. It's touted for it's cell volumizing effects, but not much of this stuff gets past the stomach.

Creatine works as advertised, but it's not much use for endurance athletes.

Creatine is a rip off. I dought anyone here would be using it. But Creatine forces water into muscle cells to promote faster bigger muscle growth. You can get the same effect by drinking ALOT of water......whats cheaper, a 1L Nalgene bottle, or ginormous bottles of Creatine???

If creatine is a ripoff what do you call L-glutamine?

With creatine at least there are plenty of double blind placebo controlled studies you can look up on Pubmed . L-glutamine has been shown to do nothing when taken orally.(it only works intravenously in hospital patients in a catabolic state)

Creatine does more than force water into cells (which it does as a side effect by osmosis). Creatine is the precursor of creatine phosphate which is the the first form of energy muscle uses under anaerobic conditions.

It really does work for anaerobic work (which is pretty worthless for endurance cyclists). Back when I was doing really heavy lifting I noticed the poundages I could use in the 5-7 rep range were higher by a noticeable margin. Most other stuff I use seems to do nothing in contrast.

If you use creatine that puts water into cells which makes the cell volumizing effect you are using OUTDATED products. Meaning, newer and better stuff is available. Creatine ethyl ester is what is good nowadays, no cell volumizing (which is bad). Basically creatine increases your ATP. Anyways cyclist don't use creatine...

Now glutamine on the other hand would be useful for cyclists. It stops muscle catabolism (right word?). It is useful to take before you go to bed, because it will help you keep muscle that breaks down when you sleep. You could also take it before hard workouts, to keep glutamine that is stripped from your muscles normally in intense workouts. Not sure what other side affects would be, since I mostly know only weight lifters who use it before workouts.

If you want to try Glutamine without spending a bucket of dough,
Walmart has Glutamine tablets for 2 or 3 bucks.

You can buy gluten in bulk at health food stores for about $3 a pound. Gluten has a ton
of glutamine. I put a little extra in the bread and pancakes I make.
I have even been known to sneak some into brownies

The thing about supplements is that a lot of them are snake oil. Sup[llement industry is great about bending studies which are remotely applicable and then manipulating them to fit their own agenda. Unless it is proven to work through double blind placebo controlled studies the theorectical benefits are meaningless.

A lot of this stuff when it's tested is found not to do anything.

The claims about glutamine's effectiveness by the supplement industry come from studies were glutamine was injected directly into the bloodstream via the intravenous route in high dosages. If was found to work well in catabolic ICU patients when used this way. Do you plan on shooting this stuff up?

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=PubMed [I just did a search of glutamine and exercise and I didn't come up with much at all.]

53-11, while you have a very valid point, backing it with with research from NIH is in my honest opinion not a good way to go. From my experience, the NIH will disprove virtually anything they think may help somebody with some random study, while a decade studies, with double blind placebo etc, performed by universities and medical centers around the world/usa will prove otherwise.

I agree there is alot of marketing BS around supplements and sometimes they work in and of themselves as placebos as our bodies have shown this ability. It would definitely be nice if there was better studies and less involvement from sides who have a stake in some sort of outcome. I will however repeat that for some reason NIH seems to have something completely against all supplements and in my opinion, thus using their "findings" would be as wrong as using some study funded by somebody else had something to gain in a positive study.

Where did I say NIH anywhere in my post?

I'm talking any double blind placebo controlled experiment from pretty much anyone (that would be better than extraploating a study done on ICU patients with high dose glutamine intravenously). Creatine has 100's of studies on Pubmed that says it improves anaerobic strength. Where are the oral glutamine studies?

I was not stating that your statement had any invalidity, I was merely pointing out my lack of trust of a nih.gov url used to back up a statement about a supplementary's effectiveness.

link is not working. Studies are not from NIH anyway. Just because it's on there doesn't mean it was NIH funded.

Most of the stuides in Pubmed that have to do with sports nutrition are in no way connected to the NIH. Pubmed is just a collection of abstracts from the major peer reviewed scientific journals.

If it is a legitimate peer reviewed scientific journal you'll find it in Pubmed.

These studies you are refering to are in Pubmed. (done at universities and medical centers)

http://www.ncbi.nlm.nih.gov/entrez/q...376&query_hl=2

Here is a review article on creatine from the Journal of Sports medicine.

Show me something like that for oral glutamine. It doesn't have to be the actual study, a review article will be fine.

I've been reading Bodybuilding magazines for a few years.

In these magazines Glutamine is considered a staple supplement, but you have to take this with a grain of salt when it comes from a bodybuilding magazines because all their advertising revenue comes from supplement makers.[Notice all the glutamine products that website sells in above link]

I got suckered into buying all kinds of crap when I believed what was in those magazines.

You are probably better off taking whey protein than glutamine if you care about money. It's a complete protein source that's cheap and gives everything you need.

Unfortunately they reference scientific studies that appear to be non-existant. They are way too biased to be taken into consideration although they seem to be echoing what one study I saw done on amino acids showed. Intense body building and taking of a 4 amin-acids caused a major deteoriation in the immune system. I do not remember what they said was used to supplement it but I think the study concluded that it did successfully combat it.
