Glutamine Products

[GdupM6]

Just wanted to see what glutamine products you guys are using and whos happy with what...

Im looking to get some glutamine and im a little confused between glutamine caps vs glutamine powder. The powder seems to be more expensive, but will the caps have the same effect as the powder?

OPTI-GLUTAMINE 1000mg 120caps (caps)

EAS GLUTAMINE 400GM (powder)

 

[dabuffguy]

Powder is MUCH more economical.

1000mg = 1 gram x 120caps = 120grams for $9

or

400grams for $16



More than 3X as much grams for only 1.4X more cost.

Go with powder.

Thx buff, just ordered 400g eas glutamine.

that's what I use. good stuff, mixes well

 

[GdupM6]

What do you mix with, just water?

 

[dabuffguy]

What do you mix with, just water?

Sure, you can do that. Or mixt it with 100% juice, or your PWO drink.

I do 15-20 grams of glutamine daily. Yum!

Why Glutamine?

Glutamine does more for your immune system and GI tract than any "bodybuilding" related benefits.

 

[dabuffguy]

The majority of the amino acids in the muscle is glutamine. The body accesses this storage when needed (mainly from intense body stress such as weight lifting) and results in catabolism. Glutamine supplementation overrides the need to use glutamine stored in the muscles and keeps your muscle at their max.

I'm using the EAS powder from supplement kingdom right now. I lift hard and heavy and need all the help in recovery i can get. Glutamine helps me minimize soreness. I've seen a big difference since the time i started taking it last summer.

I enjoy studies... so here are a few I dug up. If you want to put $$ towards anything, I may suggest a complete BCAA product or Leucine, although I do understand that some people love their l-Glutamine and won't part with it.

We examined the effect of a post-exercise oral carbohydrate (CHO, 1 g.kg(-1).h(-1)) and essential amino acid (EAA, 9.25 g) solution containing glutamine (0.3 g/kg BW; GLN trial) versus an isoenergetic CHO-EAA solution without glutamine (control, CON trial) on muscle glycogen resynthesis and whole-body protein turnover following 90 min of cycling at 65% VO2 peak. Over the course of 3 h of recovery, muscle biopsies were taken to measure glycogen resynthesis and mixed muscle protein synthesis (MPS), by incorporation of [ring-2H5] phenylalanine. Infusion of [1-13C] leucine was used to measure whole-body protein turnover. Exercise resulted in a significant decrease in muscle glycogen (p < 0.05) with similar declines in each trial. Glycogen resynthesis following 3 h of recovery indicated no difference in total accumulation or rate of repletion. Leucine oxidation increased 2.5 fold (p < 0.05) during exercise, returned to resting levels immediately post-exercise,and was again elevated at 3 h post-exercise (p < 0.05). Leucine flux, an index of whole-body protein breakdown rate, was reduced during exercise, but increased to resting levels immediately post-exercise, and was further increased at 3 h post-exercise (p < 0.05), but only during the CON trial. Exercise resulted in a marked suppression of whole-body protein synthesis (50% of rest; p < 0.05), which was restored post-exercise; however, the addition of glutamine did not affect whole-body protein synthesis post-exercise. The rate of MPS was not different between trials. The addition of glutamine to a CHO + EAA beverage had no effect on post-exercise muscle glycogen resynthesis or muscle protein synthesis, but may suppress a rise in whole-body proteolysis during the later stages of recovery

Although current research suggests that individuals involved in either high-intensity resistance or endurance exercise may have an increased need for dietary protein, the available research is either equivocal or negative relative to the ergogenic effects of supplementation with individual amino acids. Although some research suggests that the induction of hyperaminoacidemia via intravenous infusion of a balanced amino acid mixture may induce an increased muscle protein synthesis after exercise, no data support the finding that oral supplementation with amino acids, in contrast to dietary protein, as the source of amino acids is more effective. Some well-controlled studies suggest that aspartate salt supplementation may enhance endurance performance, but other studies do not, meriting additional research. Current data, including results for several well-controlled studies, indicated that supplementation with arginine, ornithine, or lysine, either separately or in combination, does not enhance the effect of exercise stimulation on either hGH or various measures of muscular strength or power in experienced weightlifters. Plasma levels of BCAA and tryptophan may play important roles in the cause of central fatigue during exercise, but the effects of BCAA or tryptophan supplementation do not seem to be effective ergogenics for endurance exercise performance, particularly when compared with carbohydrate supplementation, a more natural choice. Although glutamine supplementation may increase plasma glutamine levels, its effect on enhancement of the immune system and prevention of adverse effects of the overtraining syndrome are equivocal. Glycine, a precursor for creatine, does not seem to possess the ergogenic potential of creatine supplementation. Research with metabolic by-products of amino acid metabolism is in its infancy, and current research findings are equivocal relative to ergogenic applications. In general, physically active individuals are advised to obtain necessary amino acids through consumption of natural, high-quality protein foods.

Although skeletal muscle is capable of oxidizing selected amino acids, exercise in the fed and carbohydrate-replete condition results in only a small increase in amino acid utilization. Nevertheless, it may be important to increase the dietary protein requirements of active individuals. There is ongoing debate as to whether the amino acids for oxidation are derived from the free amino acid pool, from net protein breakdown, or a combination of both. There has been interest in the potential ergogenic benefits of amino acid ingestion; however, BCAA ingestion does not appear to affect fatigue during prolonged exercise, there is little support from controlled studies to recommend glutamine ingestion for enhanced immune function, and although glutamine stimulates muscle glycogen synthesis, its addition to carbohydrate supplements provides no additional benefit over ingestion of carbohydrate alone.

The purpose of this study was to determine if high-dose glutamine ingestion affected weightlifting performance. In a double-blind, placebo-controlled, crossover study, 6 resistance-trained men (mean ? SE: age, 21.5 ? 0.3 years; weight, 76.5 ? 2.8 kg−1) performed weightlifting exercises after the ingestion of glutamine or glycine (0.3 g?kg−1) mixed with calorie-free fruit juice or placebo (calorie-free fruit juice only). Each subject underwent each of the 3 treatments in a randomized order. One hour after ingestion, subjects performed 4 total sets of exercise to momentary muscular failure (2 sets of leg presses at 200% of body weight, 2 sets of bench presses at 100% of body weight). There were no differences in the average number of maximal repetitions performed in the leg press or bench press exercises among the 3 groups. These data indicate that the short-term ingestion of glutamine does not enhance weightlifting performance in resistance-trained men.

In Addition

There are studies out there, and I'll see if I can dig them up that say Glutamine is 1. unstable in in a physiological PH and 2. doesn't make it past the gut, which is why it's used for GI issues.

Cal you using ICE as your BCAA product?

How's the flavoring? I know BSL is the shit when it comes to flavorings, but I am enjoying my watermelon Xtend.

I've got some Grape ICE on hand if you want me to send you a sample of it.

The good thing with Xtreme Formulations is that they use superior BCAAs than most companies do. I've only had the grape ICE but if you were interested in trying some, I'd be able to hook you up with a good price, or maybe a trade.

You like watermelon Xtend? I like the green apple better and apparently they're coming up with a blue raspberry

I appreciate the generosity

When my whey reserves get low I will be picking up a 10lb bag of UP so i will more than likely order some ICE too.

My gym had all their Xtend 30 serving tubs for $12 so I bought them all lol.

Glutamine supplementation overrides the need to use glutamine stored in the muscles and keeps your muscle at their max.

While Glutamine does help the immune system it does not translate into anything used for enhanced muscle or athletic performance..

Glutamine de novo synthesis accounted for 85% of intramuscular appearance, whereas only 15% of the intracellular amino acid was derived from proteolysis

Transport from blood accounted for only 25% of the intramuscular glutamine pool turnover. In contrast, the intracellular pools of most essential amino acids, such as phenylalanine or leucine, derived largely from the extracellular space

Studies involving oral ingestion of stable isotope-labelled glutamine indicate that 50%-70% of enterally administered glutamine is taken up during first pass by splanchnic organs (gut and liver)

During exercise, substrate flux through the TCA and branched chain amino acid oxidation greatly increases (Gibala, MacLean, Graham, & Saltin, 1998). Glutamine synthesis and release are, therefore, significantly stimulated (Van Hall, Saltin, & Wagenmakers, 1999) leading to increased plasma glutamine concentrations, as observed following short-term moderate exercise or during endurance training (Hood & Terjung, 1994)


Glutamine supplementation was mostly ineffective in preventing muscle glutamine depletion in critically ill patients, because of the relative inability of this tissue in the uptake of the circulating amino acid.
