I felt the need to put this post/poll because it has been one that I've felt splits into 2 opinions. One being that it is nothing short of the holy grail and is the end all be all, and others who state it is nothing less of being worthless. Just wanting to see people's opinion.


From my own expierence/opinion, I view glutamine as one of the best hyped-up supplements to date, but lacking any real bodybuilding/resistance training evidence.



I truely believe glutamine is a result of nothing more than twisted irrelevant scientific studies that have been marketed in such a way where the bodybuilding community has been taken advantage of.(among many bogus supplements).


If there is one thing that really upsets me, as a fellow bodybuilder, is that there are too many supplement companies marketing and selling items that have zero to little scientific basis, yet herald themselves as the next best thing. Correct me if I'm wrong, but I work pretty damn hard for my money and I'm sure everyone else does too, the last thing I need is to waste money. I can do that on my own.


*****A good way of looking at this scenario is to ask yourself, 'Did Arnold have RPM, NO-Xplode, Super-Pump 250, X-Factor, etc to achieve his physique ?'
 
I used to be a glutamine man, until i dicovered bcaas. I don't think it does much in the building muscle use, but does have anti catabolic effects. It is also great for boosting your immune system.
 
Do a search on "Bobo" and Glutamine and you will find all the information you need to make your decision. For bodybuilding properties, I think it's a waste from what I have read. You can spend on your money on BCAA's or protein and be better off :)
 
numerous studies have shown high HGH ingreases after taking as low as 2-3g of glutamine. The American Journal of Clinical nutrition found this dose to increase plasma GH 430%. Now if this doesn't help a bodybuilder i dont know what does. I use GABA (which similar studies show GH increase of over 500%) and glutamine and leucine... thats the only way to go
 
since Bobo has posted on this topic many times before i dont know if hes willing to waste his time. But im looking forward to see him post in this thread. Im neutral in this topic, actually i have 1 kilo of glutamine since december that a friend ask me to buy him and he never came for it. If i decide to cap my own supps i might use it as a filler or it could work as fertilizer for my roses and a peach tree that i have @ my house.


Note: Rancid/ way over Expiration date Creatine doesnt work on plants:rofl:

Can you cite this study or studies please?
 
You're gonna have to show me those studies because 430% is a pretty damn bold claim. That's like Muscle Tech style ! Their creatine is 400% more effective.....according to them.
 
i admit "I have no brain and buy whatever is hyped-up and talked most about in forums"

just bought RPM because it is hot on this board.
also bought the numerous other exciting product releases before because they were overhyped.

i get a better placebo effect with the exciting new products.
as long as i think i'm taking the best supplements - i workout harder and thus get results.

i used to take l-glutimane years back when it was the hot new supplement.
now i take BCAAs because they are all the rage now.

i know i'm not alone on this. just man enough to admit it.
 
Nothing wrong with that Hank, we've all been through that stage in our bodybuilding expierence. Its all about being a smart shopper. Certain companies tend to have a 'reputation' of products that work, and products that consistantly don't work. Either way do a little homework before getting them.

Unfortunately though with glutamine, there's too many people swearing by it...so I guess you gotta take a chance here or there to.


It just sucks, b/c I hate seeing ppl scammed.
 
Glutamine is in just about everything anyways, I would rather just buy a protein and have that in there insread of buying a seperate product for it.

Other countermeasures, such as glutamine, antioxidant supplements and ibuprofen, have had disappointing results and thus the search for companion agents to carbohydrate continues.

Good for immune system which can be heavily compromised by weight training. Also good for digestive tract. Never heard anything about any anabolism, so the rise in GH if true makes it that much better.
 
Glutamine intake: Recent scientific research has demonstrated that consuming glutamine following exercise can accelerate muscle glycogen resynthesis and glutamine levels, which are critical in the prevention of overtraining, and the creation of an anabolic environment. I recommend ingesting 0.33 g/kg of glutamine -Charles Poliquin
 
Dr. Eric Serrano on Glutamine:

Glutamine has made a big difference in my patients, especially their immune systems, and glutamine gets rid of colds; it helps your joints; and it can increase your strength in one day. People will ask me where I'm getting this information from, but I've been playing with 11 patients with different dosages. Here's what I've come up with: you need .35 grams per kilogram of body weight. And you take it in one dose an hour before a workout. Tell me what happens during your workout. I don't care what type of workout it is.

I know that we chemistry people say it does this or it does that, but something else is going on. I think there are two mechanisms. For one thing, I think it's an excellent source of energy because the body can break it down to glutamic acid, which is kind of a sugar [although he wouldn't come right out and say it, Dr. Serrano intimated that the glutamic acid may serve as a powerful energy substrate, thereby increasing work capacity]. Number two, I have found out, and this is very important, glutamine is a marker of overtraining. If I take people, and I have them write down their workouts, and if their glutamic acid/glutamine ratio is over 10 to one, that person was invariably getting sick or developing soreness, or their performance was going down. I will tell you, papers are going to come out on it, because it's very interesting how this works. If the ratio is less than 10 to 1, you're overtraining. If I give you oral glutamine, you'll prevent overtraining. I have some theories about how it works, but I don't want to talk about them yet…if it works that way, great, but I don't want to give people the wrong idea.
 
Mauro Di Pasquale on GlutamineL

Glutamine is one of the most important amino acids in the body in that it fuels both the gut and immune system and maximizes protein synthesis. Besides being so versatile, or perhaps because of that, recent studies and articles suggest that glutamine can be used as a marker of over-training.

There are several markers that can be used to determine if someone is over-trained.4 One of them may be by measuring glutamine.

A study last year looked at various parameters of successful training, including glutamine, and found that although none of the other parameters measured (including serum hormone and cortisol levels) showed any significant changes during the training season, glutamine levels correlated with the degree of successful training, which was measured by improvements in performance. The elevations in plasma glutamine concentration observed in response to long-term balanced training in this study may be distinguishable from previous reports of decreased glutamine concentrations in over-trained athletes. Making it a potentially valuable tool in the monitoring of over-training in athletes.

The other side of the coin of course is to see if the use of supplemental glutamine has a positive effect on both preventing and alleviating the over-training syndrome. I believe that it would since glutamine not only increases protein synthesis and decreases protein breakdown but it also has positive effects on the immune system, which in turn can affect various parameters of the over-training syndrome.

As well, glutamine has recently been shown that it may act both as a substrate and as a regulator of gluconeogenesis (the production of glucose from other substrates such as amino acids, glycerol and lactic acid).5 This is important because it provides a vital supply of fuel for muscles and other tissues including the brain, and may thus improve muscle and cognitive function during training and help attenuate some aspects of over-training.

Glutamine is showing itself to be one of the most versatile and useful nutrients for sports performance. For example, a study published this year showed that glycogen resynthesis rates were higher after ingestion of a drink containing glutamine and other peptides in comparison to a drink containing just free glutamine.6

Even more interesting was a study published last year. This study looked at the effects of glutamine in promoting whole body carbohydrate storage and muscle glycogen resynthesis during recovery from exhaustive exercise.7

In this study, postabsorptive subjects (subjects have no digestion going on in the GI tract so that no nutrients are forthcoming from any food ingested) completed a glycogen-depleting exercise protocol. After their exercise they consumed 330 ml of one of three drinks, 18.5% glucose polymer solution, 8 g glutamine in 330 ml glucose polymer solution, or 8 g glutamine in 330 ml placebo. In addition, they received a primed constant infusion of glucose for 2 hours.

The authors found that Plasma glutamine concentration was increased after consumption of the glutamine drinks and that oral glutamine alone promoted storage of muscle glycogen to an extent similar to oral glucose polymer. Ingestion of glutamine and glucose polymer together promoted the storage of carbohydrate outside of skeletal muscle, the most feasible site being the liver. While we still need more studies to nail down all the specifics of the effects of glutamine on sports performance and exercise, the bottom line is, supplemental glutamine can have significant effects on many aspects of your training and help you achieve your sports and fitness goals.
 
The way I've always viewed it is like this:

Glutamine is non-essential; That means you're body can produce it from existing aminos if necessary. If you have a postive nitrogen balance, and a healthy blood glucose level, taking glutamine is like trying to put more gas in a full gastank. I'd much rather have the money to pay for gas, and if my tank's full, I can use it to buy something else. In conclusion, if you're getting ample amounts of carbs and proteins (things that can metabolically lead to glutamine, but can also lead to other things), glutamine is not going to be of much help.
